In the recent decades, a lot of Researches which are focused on Predicting the geographical distribution potential of species with goal Identifying hot habitat areas. Iran has a specific situation and varied habitats. As well as, there is a limitation in management and conservation in Iran, so conserving of Hot habitat areas is the best way to conserve a lot of species in the large landscapes. CARNIVORA has eight families in Iran, which the most of species are in IUCN Red List. The main goal of the project was making hotspot map of FELIDAE, which has a key role in biodiversity conservation of the country. In this study, we used 19 climate variables from worldclim database and presence data felid species; and used RF, SVM, MaxEnt and BRT models in Software R for species distribution modeling. After the overlay of species distribution maps using the collecting layer technique in ArcGIS10.5, to create a model with a high degree of reliability, a comprehensive map for Iranian felids hotspots was prepared using layer multiplication method. As a result, felids hotspots occurred in central deserts of Iran, parts in the north and northeast of Iran and parts of the Zagros Mountain Range in west. According to matching of prediction map of felids hotspot with map of Iranian protected areas, the pattern of habitat potential has a relatively small overlap with protected areas and have overlap with 39 protected areas. The results showed that, the RF model was the best model with excellent reliability.

Persian leopard (Pantera pardus saxicolor) is one of 37 species of cats in the world, which lives individual in most natural habitats of the country, and has a specific territory for itself. Awareness of the biological needs of species has a fundamental role in the conservation of species. To identify places merely exploited as wildlife habitat leads us to recognize optimal animal’s microhabitat parameters. Khoshyeilagh Wildlife Refuge is one of the best and most secure habitat for Persian Leopard in Shahroud city located at the north of Semnan province. The present study aimed to determine the habitat suitability of the Persian leopard with ENFA method in this area has fall 2013. The main variables considered here are the prey distribution, land cover, proximity to residential areas, transportation line, slope elevation and water resources. The results show that, in general, nearly 20% of the total wildlife refuges is a desirable habitat for the Leopard. The most important factor affecting the presence or absence of leopards in this area is under the influence of its prey, especially the wild goat and wild sheep. The most favorable habitat for leopard in this region is at high altitudes between 1700 to 2000 meters above sea level and 30 to 60 percent slopes, In fact, the center of Khoshyeilagh Wildlife refuge is the most desirable and secure place for the presence of this species due to the presence of high and rocky mountains, as well as the high concentration of prey presence.

The management of areas with landscape ecological approach helps us to have more integrated of considering completely management and also keep the area’s values.Integrity and connectivity of habitats in protected areas is important for the survival of plants and animals populations.Investigating on the integrity of these areas could help to interconnect islanded patches and preventing the negative impacts of fragmentations .This study aimed to quantify the fragmentations of the wildlife habitat in Lar national park and Varjin protected area to compare the status of the integrity of the habitat of leopard, wild sheep and wild goat species. To achieve this goal, land use maps of the areas were prepared using RS and GIS techniques and Wildlife habitat maps were also provided from Department of enviroment. In order to identify human factors influencing wildlife dispersion, the geometry of the fragmentation method was used. The results of this study indicated that by analyzing landscape metrics and geometries of fragmentation, we can identify the most important factors affecting the integrity of different species habitats, in order to protect them and preserve biodiversity. Results showed In Lar national park, soil paths, agriculture and dam factors, respectively, were identified in the creation of the fragmentation of the leopard, wild goat, wild sheep habitat. In the protected area of Varjin, agricultural use was identified as the most important factor affecting the habitat of wildlife.

Investigating damages caused by wild species to the livestock, poultry, farms and humans are important issues in wildlife management. The first step in preventing damages, is to identify factors that play important roles in conflict between humans and wildlife. In this study, 367 local inhabitants from 18 villages across Ardestan and Naeen counties of Esfahan Province were interviewed about their experiences of livestock losses due to carnivore predation, diseases and other causes from January 2016 to June 2017. Results showed that about 92.7 percent of the livestock owned by respondents were attacks by grey wolves. Respondents reported negligible livestock loss to other carnivore species including jackal, common fox, striped hyena, wildcat, caracal and leopard. Yet, livestock loss to disease and other natural causes was about 2.5 times greater than the losses due to the wolf attacks. We argue that the local people’s perceptions about the wolf as main threat to their livestock has shaped through long exposure to the species and the wolf behavior. Locally-affordable preventative methods such as keeping the livestock at predator-proof corrals and use of trained sheepdogs, as well as grazing pastures in avoiding places where wolfs are abundant, especially during the wolf breeding and nursing seasons, can be considered as strategies to decrease human wolf conflicts.

Today, habitat separation and fragmentation have serious effects on wildlife populations. Developing of protected areas and creating connection between them is one of the most important ways of dealing with this problem. Corridors play an important role in the distribution and survival of wildlife populations. This study aimed to evaluate the Damgahan region as a corridor between Kalmand- Bahaduran protected area and Shirkouh hunting prohibited area. Area of the studying region was 106 hectares. We used the present points of the species and environmental variables to asses the habitat suitability of Wild Goat by using Analysis Ecological Niche Factor. Then, corridors were defined by using habitat suitability maps and the least costly path in GIS. The most important variables influencing present of wild goats are rocky areas, slope, elevation and vegetation type. The marginality, and specialization were estimated 0.838, 3, respectively, that indicate the Wild Goat prefers the environmental conditions above than the regional average and, this species is dependent on the limited range of environmental conditions. More than 60% of the proposed corridors constitute the suitable habitat. By using these calculations, seven corridors were identified for connecting of the areas. Results showed Damgahan area has high suitable, lowest cumulative cost and the lowest human conflicts, among other corridors for Wild Goat.

This study has been carried out in order to investigate the Fundamental niche of Wild sheep (Ovis oriantalis) in the protected areas of Lashgar Dar-Golaparabad, Palangab and Alvand-Chalkhatoon-Rasvand. Similar habitat variables in the entire habitat were identified and digitized. Then, by using the maximum entropy (MaxEnt) model, the realized niche was investigated in the studied areas. In order to achieve the Fundamental niche, the range which contains all selected areas was selected and the modeling of Fundamental niche using MaxEnt model was conducted. The values of the habitat variables of the maps were extracted according to the presence points and then the K-Means cluster analysis was used to cluster the presence points according to similarity. Finally, by using overlap indexes (Schoener's D, Hellinger's I) and breadth (Levin's B1, B2 (uncertainty)), the amount of niche overlap and niche breadth of the species was measured. The results of cluster analysis showed that according to the habitat variables of the presence points, the regions of Lashgdar-Golaparabad and Alvand-Chalkhatoon-Rasvand have the most similarity. However, based on the results of maximum entropy model, the most overlap of the Fundamental and the realized niche was between the no hunting areas of Palangab and Lashgardar-Golparabad, and on the other hand, the specialization of the Wild sheep in the Fundamental and the realized niche in Alvand-Chalkhatoon-Rasvand areas was more than other regions.

Wild sheep (Ovis orientalis) is of prominent mammals in hilly regions and in terms of conservation is among vulnerable class of the red list of the International Union for Conservation of Nature. In this study, the wildlife refuge of Boroueieh area located in south of Yazd province was investigated as one of habitats of wild sheep. In this regard, desirability modeling based on the presence data was conducted using the maximum entropy (MaxEnt). For modeling and managing wild sheep as the prominent species of hills and mountain ranges, firstly the factors influencing the distribution of the species should be identified and then the habitat desirability model should be designed to protect and manage these habitats in order to protect the target species. For modeling habitat desirability, presence points were dependent variable and environmental factors were considered as independent variable. The purpose of this research was to determine the suitable habitat for wild sheep using the presence points and environmental variables by maximum entropy model. The desirability map shows that variables such as 30-50 percent slope, rangeland and hill areas are the important determinants of the desirable habitat for wild sheep. Considering the amount of AUC (that is 0.939), the model has a very good predicting power and jacknife graph showed that the model has been successful in prediction of the presence points as desirable habitat. According to the results of modeling, 28.24% of the Boroueieh area is desirable habitat for wild sheep.

Long term sperm storage is major factor of artificial insemination in animal improvement. Nevertheless recovered fertility of frozen–thawed sperm is very important. This experiment was carried out in order to study of antioxidant effects of fennel (Foeniculum vulgare) aqueous extract on the quality of frozen–thawed Ghezel ram semen. After extraction procedure, different levels of fennel extract (0, 2, 4, 6, 8, 10 and 12 ml as experimental groups) were added per deciliter (dl) of extender. After chilling, diluted semen were packaged in 0.5 ml straws and stored in liquid nitrogen for 3 weeks. This experiment was performed with 5 replications (with 10 straws in each replicates) per experimental groups. Evaluation of live sperm using of eosin-nigrosin staining showed addition of 6 ml Fennel extract had higher live sperm than other experimental groups (P<0.05). Plasma membrane integrity was carried out by Hypo Osmotic Test (HOST) that declared the healthiest membrane was observed in 6 ml extract group (P<0.05). There were significant differences among experimental groups in plasma membrane integrity and lowest value was observed in 12 ml extract group (P<0.05). Sperm motility evaluation by CASA declared significantly higher motility in 6 ml extract group versus other groups (P<0.05). Study of oxidative damage showed lower amount of Malondialdehyde (MDA) in 12ml extract group than other groups (P<0.05). Although the results declare the substantial differences among experimental groups but base on this experiment, It seems, use of 6 ml fennel aqueous extract per dl extender, lead to positive effects on frozen-thawed sperm quality.

Fourthy eaight Atabay ewes were randomly allocated as CRD in 4 treatment groups. Treatments were as (1) pretreatment with CIDR for 12 days and then receiving PGF2α at the time of withdrawal of the CIDR (2) pretreatment with CIDR for 12 days and then receiving eCG (3) pretreatment with CIDR for 7 days and then receiving PGF2α and (4) pretreatment with CIDR for 7 days and then receiving eCG. No significant differences were observed in term of male to female lambs ratio, lamb birth weight and weight after weaning (p>0.05). percentage of estrus were 100, 75, 58.33 and 50 respectively. The highest percentage of estrus were observed in treatment 1 with a significant difference with others (p<0.05). parturition rate was 88.33, 88.88, 100 and 100 percentages respectively and this term in treatment 3 and 4 were higher than treatment 1 significantly (p<0.05). lambing rate were 130, 100, 128 and 120 percentages respectively. Twining rate were 30, 0.0, 28 and 20 percentages respectively. The lowest Lambing and twining rates refer to treatment 2 with a significant differ with other treatments (p<0.05). In conclusion, long time CIDR (12 days) and injection of PGF2α had better results in comparison to eCG hormone and pretreatment with CIDR for 7 days had no significant difference between PGF2α or eCG injection. Also injection of eCG after CIDR removal (7 days) compare to (12 days) caused an increase in efficiency of parturition rate, lambing rate and twining rate in Atabay ewes.

In this research, production, reproductive, managerial and economic characteristics of Moghani sheep breeding during the annual production cycle in nomadic and rural systems were used to identify the traits' performance and economic analysis of both rural and nomadic systems in Ardebil province. In order to estimate the economic value of the traits, the models that describe the production and reproductive conditions at the breeding ground of the sheep breed in the rural and nomadic system and the economic values of the traits were calculated using MATLAB software. The effect of increasing the unit of variation in average of attributes on the revenues and costs of production systems and the resulting economic value showed that in both systems, in the case of an increase in the average traits, the survival rate of the ewe, the pregnancy rate, the number of births per year, the weight of the wool and The weight of milk increases the income, and if the average weight of the alternative increases, it will increase the cost and eventually reduce the income. In nomadic and rural methods, the relative economic coefficients of all traits except the alternative weight trait were similar to those of most of the research carried out. Economic analysis of the system showed that in rural conditions, the income, expenses and profits per head of the ewe per year were 3864702.32, 3293308.57, 571393.75 Rials, in nomadic conditions of income, expenses and profit of the system, respectively, 8134659.38, 11072563.71 and 2937904.33 Rials. In order to investigate the effects of economic and biological variables on economic value, sensitivity analysis was performed. The cost-benefit analysis for each ewe's head was done in the Moghani sheep under the rural system, with the largest share of labor costs and the largest share of income related to the sales of live weight of lambs. While sheep in the nomadic system, the most was the cost of nutrition and the highest income associated with live weight during sales. Also, to study the changes in the factors affecting economic efficiency as a performance index, some of the parameters of the model were changed by 50 percent in the positive and negative directions. It was shown that if the traits change, the survival rate of the ewe, pregnancy rate and milk weight in the direction Positive increases the productivity index, but in the case of weight gain in the positive direction, it decreases productivity.

One of the most problems in herds of tribels is lossing weight of sheep spicially in lambs of Moghani breeds during the migration.This study carried out in five herds of moghani sheep tribes in Ardabil province. The objective of study was calculation of weight loss and investigation of weight changes in moghani lambs in different migrationsystems.This experimentused an unbalanced compelet randomized design at five migration system.The treatments were by foot migration without complementary feeding (control group), by foot migration with complementary feeding, on car migration without complementary feeding, on car migration with complementary feeding and on car migration at night (without feeding). Results showed that the effect treatments on lambs weight loss is significant(P<0.05). Control group with the highest weight loss (2.65 kg) had significant difference with other treatments (P<0.05). However lowest lambs weight loss belonging to the on car migration with complementary feeding system (65gr). Comparison of treatments from economic point was showed that migration on foot with complementary feeding was better than others systems.

Leptospirosis is one of the most commonly diagnosed diseases of humans and animals around the world, which is caused by direct or indirect contact with the urine of infected animals. Since there is no basic information about the condition of Golestan province in this survey, Leptospirosis was studied and monitored in this survey. In this regard, from 910 cows of different age, blood samples were collected and the samples were examined by microagglutination method. Data were analyzed using SPSS software and Chi-square test. Finally, the results showed that 170(%19) samples had a positive serological response of total samples, of which 86 responded with only one serovar. In all samples with serum positive serum response, 41.15% showed gripotyphosis, 35.89% with Sirjrohardjoo, 22.49% with canicola and 0.48% with Pomona. Also, the highest frequency (33.49%) was observed in the 1,400 headline. It is worth noting that none of the samples were detectable against the serum hemorrhagia of the head. Also, the results of statistical analysis did not show a significant difference between season and age and infection rate.

The selection of useful mutations in some populations will leave footprints at the genome level. Because of the link between these regions and important economic traits, genomics is one of the important issues in animal genetic research. The aim of this research is to identify regions of the genome which carrier signature of selection in Kurd horse using 70kb SNP markers. 28 horses selected from the different area of Kurdistan and Kermanshah, after collected sample, DNA extracted, they were genotyping. To detect footprint of signal selection, extended haplotype homozygosity (EHH) and integrated Haplotype Score (iHS) was used. The using of iHS statistics, 9 genomic regions on chromosomes 5,7,11 and 15 as regions candidate of footprint selection, identified. For the detect effect of selection on this region, used of EHH as well as investigate of bifurcation diagram of haplotype and LD. In order to evaluate the possible genes and QTLs in selected candidate regions, used of the horse SNP databases (HSDB) and the QTL of the animals. The regions on 7 and 11 chromosomes were observed as candidate positive selection while in other regions (chromosomes 5 and 15), notwithstanding allele frequency, it wasn’t affected positive selection so these alleles were the common and old alleles. In these regions, a number of genes and QTLs were identified that are active in the muscle, immune system and intracellular activity. Therefore, these genomic regions of Kurd horse, probability were targeted positive selection.

According to IUCN estimates, about 30% of the extinction of species until 1980 was due to habitat destruction. Climate change has been recognized as the most important factors of habitat destruction in recent years. Forest are one of the most sensitive ecosystems to climate change, hence forest species such as squirrels are very vulnerable to climate change. Predicting the effects of climate change on species habitats can assist in species conservation planning. Habitat modelling is one of the most widely used methods to study the effects of climate change on species and their habitats in the near and far future and the maximum entropy model is one of the most efficient models in this field. For this purpose, in this study the maximum entropy model was used to identify suitable habitats for Persian squirrel in Lorestan province’s forests both in the present time and in the future depend on the CCSM4 climatic model by 2050. The AUC of 0.92 represents the satisfactory performance of this model in this study. Results indicated that about 57% of forests in Lorestan province are suitable for Persian squirrel, of which 17.78% has high suitability, 25.59% moderate suitability and 13.63% low suitability. In addition, the results indicated suitable forested areas for Persian squirrel will decrease from 57% to 22.58% by 2050 based on CCSM4 climatic model, of which 5.36 will have high suitability, 8.2% moderate suitability and 8.99% low suitability.

The threats and human conflicts in the Dena protected area, the existence of many villages, the destruction of oak forests and the expansion of agricultural lands have limited the habitat of Iraniansquirrel species in this area. Habitat assessment models predict the distribution of species and their habitats, and therefore can be used as a suitable tool for conservation and management purposes.With the aim of modeling Iranian squirrel habitat in the spring and summer of the year, the ecological Nich factor analysis (ENFA) method has been used in the Biomapper software environment. In this study, the presence of species as dependent variable and eight environmental variables were used as independent variables. These layers were prepared and analyzed. The desirability map of thehabitat for Iranian squirrel species indicates that the desirable habitat in the west and southwest of the Dena Mountain and in areas with oak forest cover with a low density with a slope of less than 14% in the spring and 11% in summer Is. Based on the amount of specialization, the most important factor affecting the ecological niches of the species studied in the spring and summer is the environmental checkpoint, gradient, vegetation index and distance from the road.Oak seed plays a major role in the range of domestic squirrels in Iran, In the spring, due to ashortage of food, especially oak seed, it is higher than in summer.

Considering the importance of conservation of biodiversity in the country, the proper selection of conservation areas representing wildlife and habitat diversity of the country is essential. Therefore, we conducted this study to evaluate the performance of current conservation area network in conservation of biodiversity throughout the country and to introduce new conservation areas to improve biodiversity coverage inside the network by applying systematic conservation planning. To do so, a number of 126 biodiversity surrogates including 20 mammals, 20 birds, 53 reptiles, 10 amphibians, 19 ecoregion classes and 4 high species richness classes of monocotyledon endemic plants were chosen and their current conservation level were investigated. The results indicated that for 43 vertebrates, 11 ecoregion classes and 2 class of endemic monocotyledons less than 10% of available geographical ranges are under conservation inside the present conservation area network. Moreover, the application of the conservation planning software Marxan to introduce new complementary conservation areas to current network indicated that about 20% to 30% of the country area should be conserved. Moreover, 15% of the country area is completely irreplaceable in conservation of its biodiversity. The result of this research suggests new areas to the department of environment of Iran to be introduce to the current conservation area network. While, it considers important factors such as the least possible area and anthropogenic conflicts and the highest efficiency in conservation of biodiversity.

Assessment of land ecological capability as the core of environmental studies, is necessary before development for different uses. To achieve the planned objectives according to the IUCN, it is necessary for protected areas to be zoned in the process of evaluation of environmental capabilities. This study was done to determine the ecological capability and zoning of Bashgol protected area by systemic analysis method for the conservational reclassification of the Protected area. To achieve it, 1012 environment units in the area was achieved with preparing the map of stable and unstable ecological resources, and socioeconomic resources of area and its analysis and concluding by GIS (scale 1:25,000). The maps of ecological potential were prepared by comparing the homogeneous units with special ecological model of the area, and then with integration of units with the same usage, first base map of zoning and eventually the final zoning map with prioritizing and organizing the primary zones as the units of planning was prepared. The results showed that the percentages of the restricted nature zones, the protected zone, the extensive recreation zone, the other uses zone, the recovery and restoration zone, the buffer zone, the historic and cultural zone and the special use zone, are 25.14%(6133.14 hectares),58.41% (14250.99 hectares),0.32 %(77.4 hectares),13.63%(3324.65 hectares), 1.87%(456.87 hectares),0.6%(145.26 hectares),0.04%(9.12 hectares) and 0.005%(1.32 hectares), respectively. Due to the large extent of the protection zone, Bashgol area has high conservation value, but does not have one of the necessary zones (Intensive recreation zone) to be upgraded to national park level.

Development of transportation network and the increasing number of vehicles have become worldwide threat to wildlife habitats and birds. This study investigates the effect of road on the diversity and abundance of birds in an urban park located between Zayandeh-rood River and one of the main heavy traffic highways in Isfahan city. To do so, three transect were designed with 65, 335 and 605 m distance from the highway, 270 m distance from width and 150 m distance from length of each other. The number and distribution pattern of birds were recorded using point-counting method, every 5 minutes from sunrise to 2 PM o’clock and repeated 6 times during seasons. Birds were recorded, in each transect using binoculars and audio tracking and were identified filed guides. The Canon SX50 was used to take photos. In total, 39 species belonging to 20 families and 9 orders were identified. Based on the results of one-way ANOVA and Duncan's test, there was a significant difference in mean of species presence between transects. In transect 3, Jack-knife index comprises 73.8 percent of the species richness. Richness and evenness indices were higher in transect 3. Higher diversity and density of birds in transect 3 could be due to the longer distance of this transect to the highway, its safety, intense vegetation cover and adjacency to agricultural fields and Zayandeh-rood River.

The new approach of food industries is natural preservatives usage instead of synthetic ones. This study was investigated to introduce a palatable and stable new product resulting from dipping of chicken breast meat in barberry extract (BE) and Corn Zein coating enriched with Allium cepa essential oil (A) during refrigerated storage. Treatments examined in the present study were the following: C (control samples were dipped in sterile distilled water), BE1.5% (samples were dipped in 1.5% barberry extract), BE3% (samples were dipped in 3% barberry extract), BE1.5%-CZ( samples were dipped in 1.5% barberry extract and Corn Zein), BE3%-CZ (samples were dipped in 3% barberry extract and Corn Zein), BE1.5%-CZ-A2%(samples were dipped in in 1.5% barberry extract, Corn Zein and onion essential oil ) and BE3%-CZ-A2%( samples were dipped in 3% barberry extract, Corn Zein and onion essential oil). The samples were stored at 4 °C for 15 days and analyzed at 3-day intervals. All of treatments significantly (P < 0.05) decreased mesophilic total plate counts (TPC), Pseudomonas spp., lactic acid bacteria (LAB), Enterobacteriaceae, Psychrotrophic bacteria and yeasts-molds as compared control during refrigerated storage. The enriched Corn Zein coating to onion essential oil significantly (p<0.05) improved above effects. It was concluded that barberry extract with Corn Zein coating containing onion essential oil is able to decrease microbial spoilage in chicken breast meat during refrigerated conditions.

The use of medicinal plants instead of antibiotics is highly effective in preventing and treating many diseases of livestock and poultry due to their multiple properties. In this study, gene expression changes of IFNγ were evaluated with the addition of Valerian and oregano oil in Arian broilers. The experiment was conducted in a completely randomized design with 7 treatments and 4 replications. Experimental treatments included control, antibiotic, probiotic, Valerian oil and oregano oil at levels of 200 and 400 mg/kg. Body weight traits at 6 weeks, feed rate, feed conversion ratio and IFNγ gene expression were measured. To determine the expression of IFNγ gene, the total RNA was extracted from four hepatocyte repeat lymphocytes of different treatments and, after generating the cDNAs of the samples, the expression of the genes was investigated by Semi-Quantitative RT-PCR. To investigate the effect of experimental treatments on traits and compare the mean of treatments with GLM and Duncan test (p <0.05), SAS software (9) was used. The results were analyzed using GLM software (SAS 9) and the mean of the treatments were compared using Duncan test. The results showed that expression of IFNγ gene was significantly different at different levels of treatment, so that it was the highest at 400 mg/kg and the lowest amount of expression was observed in treatment of oregano oil (200 mg/kg). In general, the results of this study showed that the use of oregano oil in broiler chicken diet improves immune function and decreases mortality rate.

In the present study, the effect of temperature on growth and survival of Huso huso larvae in the stage of larvae to yolk sac absorption was investigated. In this experiment 450 freshly hatched larvae of great sturgeon with initial weight of 20±0.97 mg were used in five thermal treatments at 10, 15, 18, 21 and 24 °C and three replicates for each in 10 days, raised in 20 l plastic container with the inflow rate of 2 l/min. The results of this study showed that the higher temperature of the water caused the more infant mortality and less survival. The temperature of 10°C created by a cooling machine for larvae exposed to this thermal group was fatal in their first minutes of arrival and their mortality rate reached to 100%. Among other thermal groups, the highest mortalities occurred at 24°C, (7.33±1.15) and the lowest losses happened at 15°C (1.00±0.32). As water temperature rises to 24°C, the time of absorption of yolk sac in great sturgeon larvae obviously decreases. The minimum growth rate of larvae was seen in 21°C. Therefore, lower mortality and higher weight gain of larvae (84.00 ±0.8 mg) at 18°C could be considered the appropriate temperature for culture in this period.

The aim of this study was to investigate the primary and secondary responses of Siberian sturgeon (Acipenser baerii) to handling stress on at two different sizes. In this study, the fish were distributed in small and large sizes with mean weights of 672.27 ± 2.54 g and 1078.5 ± 5.30 g, respectively, in six replicates with equal biomasses. Six blood samples were randomly taken before the stress thereafter three blood samples were taken at 1, 3, 6, 12 and 24 hours after acute stress (the fish were exposed to air for two minutes) to examine the physiological changes of blood. Cortisol levels increased in both sizes, although there was no significant difference in experimental treatments. According to the results, blood glucose increased in large size after stress and a significant difference was observed (p ˂ 0.05), but no significant was observed in small size (p ˃ 0.05). Lactate levels significantly increased in both sizes after stress (p ˂ 0.05). The results showed that large-sized fish show larger stress response than small size, and therefore they tend to be more susceptible to stress.

For protection of aquatic ecosystems and fish, enough knowledge on habitat requirements of aquatic species plays an important role. Therefore, the purpose of this study was investigating Habitat Suitability of Persian sturgeon (Acipenser persicus Borodin, 1897) in the southern of Caspian Sea. Relationships among important factors of effective at distribution this species (benthos, temperature, salinity, O2, %TOM, %Silt-clay and depth) with its catch were evaluated during April 2010 to December 2016. This study focuses on the number of 3138 specimens were caught by fixed gill net and beach seine. Also for calculate environmental factors used from data of satellite images, sampling and past studies. For survey this relationship, used Redundancy Analysis (RDA) method using CANOCO software. Results showed that temperature, %Silt-clay, benthos, salinity and %TOM were important factors at distribution this species. But O2 and depth factors don’t have a significant effect on the distribution of Acipenser persicus. The mostly-selected environmental factors of this species were Optimum temperature ranging from 12 to 25˚C, its favoritesubstrate gravel, sand and silt, salinity ranging from 11 to 14 ppt, %TOM ranging from 2.2 to 3.3. Result this study showed that is high correlation among the catch data of Acipenser persicus,environmental factors and benthos. Therefore, awareness of the relationship between environmental factors and the catch data of Acipenser persicus will help these findings to be used in management, conservation programs and the prevention of the extinction of this species.

This research investigates the effect of Artemia urmiana replacement in Salmo trutta caspius larvae feeding on its survival index. The present study was carried out in a complete randomized design with four dietary groups including: treatment1 (control diet with commercial formulation), treatment 2 (diet with 25% decapsulated Artemia cyst and 75% concentrate), treatment 3 (diet with 50% decapsulated Artemia cyst and 50% concentrate), treatment 4 (75% decapsulated Artemia cyst and 25% concentrate) to final weight of1 gram. This experiment was performed in 4 sectioned trays, each divided into three equal parts with a fine metal mesh net and 300 larvae per part with 2 replicates and a total of 900 larvae. The larvae were prepared from the propagation center of Kelardasht .They were firstly weighed accurately and their average weight and biomass in each treatment was determined. The mean initial weight of larvae was 25 ± 120 mg, respectively. During the experiment, the survival rate (SR) was calculated. Comparison of mean (± SD) of survival percentage of the experimental groups showed that treatment 2 with 98.71 ± 19.19% and treatment 1 with 86.83 ± 1.21% had the highest and lowest survival rates, respectively. Comparison of this index in treatments 2 to 4 showed no significant difference (p> 0.05), but there was a significant difference compared to treatment 1 (p <0.05). According to the results of this study, it can be concluded that feeding with decapsulated A.urmiana cyst significantly reduces the mortality rate of S.trutta caspius larvae.

Among the various viral diseases in fish, viral hemorrhagic septicemia virus (VHSV) could be mentioned as the most significant viral infection which has now been identified for its worldwide devastating effects on trout. In the present investigation, the influence of the miR-731 on eye damage with exophthalmos (pop-eye) of VHSV in rainbow trout (O. mykiss) was examined. In current clinical trials, fishes (20± 1) g were examined to determine the possibility of pretreatment VHS disease by miR-731 in four main groups, including negative control without any injection, vehicle that received saline, positive control that were infected by VHSV (IP), and experimental group that were received miR-731 48 hour pre viral injection. Each main group subdivided into three subgroups. Carbonic anhydrase (CA) activity plays an important role in controlling aqueous production in the eye and in regulating intraocular pressure. The rate of carbonic anhydrase on trout eye was assessed in each group. Our results revealed that all animals in the positive control showed pop-eye, whereas in the negative control, the vehicle and the experimental groups were not observed any exophthalmos and there is significant difference between the rate of carbonic anhydrase in the positive control group and other groups. Although more studies are needed to verify the exact mechanisms of miR-731 viral inhibition pathway, present results partly proved that miR-731 pretreatment could decrease the sign of VHS disease eye damage.

The effect of marine oils has been proven in many diseases due to the presence of n-3 fatty acids. Most of the clinical effects of n-3 fatty acids are due to the presence of Docosahexaenoic acid (DHA( and Eicosapentaenoic acid (EPA), which has so far not been found in any other food, except in fish. The purpose of this study was to investigate the effects of different levels of fish oil and canola oil on diet, on growth, survival and body chemical composition of Fattening rainbow trout (Oncorhynchus mykiss) Which ultimately can compensate for the deficiency of n-3 fatty acids in the household food basket and it is an important step towards the health of the community. For this purpose, three experimental diets were prepared with the same protein level (40%) and different fat levels (the first diet with 10% fish oil, the second diet with 10% canola oil and the third diet with 5% fish oil and 5% canola oil) and each one with three repetitions and 270 rainbow trout with an average weight of 100±10 g were cultured with a density of 30 in per cage for 56 days. Based on the results, there were significant differences between mean weight, body weight gain, feed conversion ratio, specific growth rate and condition factor in all three treatments (P<0.05). However, there was no significant difference in terms of survival rate and body chemical composition between treatments (P>0.05). In general, the results showed that the third treatment (5% fish oil and 5% canola oil) in the diet improved the growth indices, survival rate and condition factor (P<0.05).

The use of chemical materials such as malachite green to disinfect fish eggs is banned in many countries due to its reversed environmentaleffects. The purpose of this study was to investigate the effect of garlic extract as antifungal agent on eggs of oncorhynchus mykiss during the incubation period and to compare its effects with malachite green.24 hours after fertilization, eggs were treated with three concentrations of garlic extract (50, 100, 200 mg/L) and three replicates per concentration using static bath method every other day for 30 min and 2 mg/L malachite green using the same method every other day for 30 min. The control group didn’t have any antifungal agent. The results of study showed that the highest eye egg mortality rate of control group was 1477±6.94 (33.35±0.14%) (P<0.05). Also, the mortality rate of eye egg 200 ppm of garlic extract treatment was (576±5.60 egg, 13.11±0.09%) which was significantly lower than the other treatments (P<0.05). the mortality rate of eggs between eye egg stage and hatching stage in the 200 ppm of garlic extract treatment was 335/6±9.88 egg (7.62±0.21%); however, it was 666±7% egg in the control group . malachite green (with 207±4.2 dead eggs, 5.74±18%), and 200 mg/l garlic extract (11.82±.25%, 270.3±7.3) treatments had lowest mortality rate between hatching stage up to 1 gr weight (P<0.05) . However, in this stage, the control group showed the highest rate of egg mortality among all treatments. Since no apparent deformities and abnormalities were observed in hatched larvae, suggested garlic extract with 200 mg/l concentration, as an environmental friendly matter, can be used for disinfection of O. mykiss eggs during incubation period.

In this study, the effects of iron nanoparticles on serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT)enzymes and gut bacterial flora of rainbow trout (Oncorhynchus mykiss) were investigated. For this purpose, after biometrics of fish with mean weights 12.94 ± 0.35 g (Mean ± SD), the fish were randomly released in 12 tanks, containing 500 liters water (30/ tank) and fed with different diets twice a day for eight weeks. For each treatment, three replicates were considered. Control treatment diet was prepared by adding 60 mg/kg FeSO4.7H2O powder to other dry matters and diets of other treatments containing iron nanoparticles were prepared by adding 30, 60 and 90 mg/kg of Fe3O4 nanoparticles as iron resource (replace iron sulfate) to the base diet. Biometrics was used to check body weight every 14 days. For determination of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes and gut bacterial flora at the end of the experimental period, the fish were randomly sampled (3/ replicates). According to the results the highest amount of AST and ALT was obtain at control treatment and treatment contained 60 mg/kg iron nanoparticles and also there was a significant difference between control treatment and treatment with 90 mg / kg iron nanoparticles (P<0.05). The lowest levels of these enzymes were observed in the treatment containing 30 mg/kg iron nanoparticles, which did not have a significant difference with treatment containing 90 mg/kg iron nanoparticles (P>0.05). In addition, different doses of iron nanoparticles had not significant effect on gut lactic acid bacteria of rainbow trout, but the total number of gut bacteria (total count) in treatment fed with 30 mg/kg iron nanoparticles was significantly lower than other treatments (P<0.05).

The new approach of food industries is natural preservatives usage instead of synthetic ones. Tomato pomace is by-product of tomato processing factories that can be introduced as a good alternative to synthetic preservatives with added health benefits. This study aimed to examine the impact of tomato pomace extract singly and combined enriched Arabic gum coating to dill essential oil on the shelf-life of rainbow trout fillets during refrigerated storage. Used treatments were as follows: Control, ET 3%, ET 6%, ET 3%+GA, ET 6%+GA, ET 3%+GA+D 2% و ET 6%+GA+D 2%. The samples were stored at 4±1 °C for 15 days and analyzed at 3-day intervals. During storage period, all treatments showed a significant decrease (p<0.05) in total viable counts, Pseudomonas spp., lactic acid bacteria, Enterobacteriaceae, Psychrotrophic bacteria and yeasts–molds compared to the control. The enriched Arabic gum to dill essential oil significantly (p<0.05) improved above effects. According to obtained results, it is concluded that tomato pomace extract in combined to Arabic gum coating containing dill essential oil is able to decrease microbial spoilage of rainbow trout fillet in refrigerated storage.

Fish cage culture is a new surrounding aquaculture system. However, waste and different pollutions may alter the community structure of zooplankton in water column by physicochemical exchanges. This study was designed to monitor the impact of Common Carp cage culture on the zooplankton community structure in Golestan reservoir. In order to study the physicochemical factors of water and zooplankton population, sampling was done in two seasons of spring and summer at six stations; 5 m, 100 m, 200 m, 400 m, 1000 m and 2000m from cage. The results showed that the Common Carp cage culture did not have a significant difference on the physicochemical parameters and zooplankton abundance between seasons and stations. The most of the factors are affected by the season. In this study 10 genus of zooplankton were observed. One species from Cyrtophoridae, 2 species from Hymenostomatida, one species from Oligotrichida, 2 species from Diplostraca were identified. The other orders including Cyclopoida، Calanoida، Arcellinida and Ploima had one species each one. Cyclops has the highest abundance in spring (64%) and summer (21%) seasons. The biodiversity indices of zooplankton were lower in spring than summer. The CCA tests showed that the DO factor in the spring and NH3 in summer had a negative relationship to abundance of zooplankton. It seems the Common Carp cage culture in Golestan reservoir has no significant effect on the water quality and Structure of zooplankton population as well as the changes observed in the zooplankton structure was related to seasonal variations.

In whole duration nurture small fishes nourished duration test carried by food constant Testes were done in 3 treatment and 3 repeat to the following: control: twice in day nourish, treatment 1: two week nourishment+ one week starve, treatment 2: one week nourishment+ two week starve, rate nourish on the basis of 8% weight of total body of small fishes one repeat on. In growth period, growth parameters were studied. Results showed that between body weights of studied fish statistical difference of (p< 0.05). Small fishes in control that nourished have more increase of weight. Statistical differences were observed between treatments in body rate increase, final weight, coefficient of of food, coefficient of special growth. But best coefficient food change relevance to treatment that one week nourish and 2 week starved, in carcass analysis more protein and lest fat were relevance to treatment 3. Finally, starvation will have a significant effect on the body weight of the Cyprinus carpio, but under the test conditions, including changing water through siphoning, aerating by air pump and indoor saloon, feeding to achieve the best growth rate will be recommended.

This study was investigated the protective effects of pectin on changes in some blood biochemical parameters against cadmium exposure in common carp. Fish juveniles (37.5±7 g) were fed by 6 different diets during 21 days. The first group (control) was only fed by commercial diet. The diets for second and third group were prepared by addition sublethal dosage of 150 and 250 mg cadmium (per kg diet), respectively. For the fourth and fifth groups, the commercial diet was supplemented by 150 or 250 mg cadmium/kg diet plus 0.5 percent of pectin. Similar level of pectin has been used as a unique feed additive for the last group. Following 21 days feeding trial, blood sampling was withdrawn separately for all six mentioned groups and some plasma biochemical parameters were analyzed, subsequently. Plasma levels of AST, ALT, ALP, total protein, albumin, globulin, triglyceride and creatinine were remained undisturbed in pectin plus cadmium groups compared to control (P>0.05). On the other hands, the most above factors were changed in only cadmium administrated groups compared to the control. Based on obtained results, it seems that pectin potentially can ameliorate the harmful effects of heavy metals.

The contamination of natural ecosystems with a wide range of environmental pollutants, especially heavy metals, has attracted much attention in recent decades. Common carp, due to its large body size and higher average age, can absorb high levels of heavy metals. Also, the omnivorous regime and the use of benthos have allowed the accumulation of high amounts of heavy metals in various organs of this fish, especially the liver, kidney and muscle. In this study, the amount of lead in muscle of common carp (Cyprinus carpio) and water of Choghakhor wetland was investigated. Accordingly, 45 specimens of common carp were sampled by a fishing trip with 45 water samples at three stations in the summer and spring of 2017. After determining the age, sex and weight and measuring the physiochemical parameters of water, the amount of lead in water and fish tissue after extraction was measured using a graphite furnace atomic absorption spectrophotometer. The results showed that the mean lead concentration in carp (0.2 mg/l) is lower than the maximum acceptable level in the WHO (0.5 mg /l). But with increasing the fertilizer and chemical pesticides, it is likely that the level of contamination will increase gradually to a degree of risk. The presence of extensive agricultural activities on the wetland is one of the sources of wastewater coming from fertilizers and pesticides that has affected aquatic life.

The aim of this study was to evaluate the toxicity of nanoparticles in different concentrations. Iron nanoparticles are widely used as a contrasting element in nuclear magnetic resonance (MRI), as well as for thermotherapy of cancer cells. A batch of juvenile carp (Cyprinus carpio) averaged of 11 ± 0.8 cm in length and 17 ± 0. 6 g in weight were acclimatized to laboratory conditions for 2 weeks prior to the experiments. After exposure to different concentrations (10, 30 and 50.0 mg.L-1) of waterborne nano-iron for 0, 1, 7 and 14 days, the variation in antioxidant enzymes activities including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and levels of malondialdehyde (MDA) in liver of the fish were evaluated. The results showed that exposure to nanoparticles led to a significant time-related change in antioxidant enzymes activity and increase in MDA level (p<0.05). Alteration found in the antioxidant defense systems is considered as a biological response to exposure to sub-lethal concentrations of nano-iron by exhibiting an obvious adaptive threshold. Therefore, that the biomarkers such as antioxidant enzymes and MDA level can be used for monitoring oxidative stress in carp.

In this study, to investigate the effects of silver on juvenile common carp (Cyprinus carpio), the fish were exposed to sub-lethal concentrations of silver-nanoparticles and silver nitrate. For this purpose, at first, Lethal Concentration (LC50-96 h) for two silver forms was obtained and then fish were exposed to sub-lethal concentrations (0.04 and 0.08 mg/L for silver NPs and 0.025 and 0.025 mg/L for silver nitrate) for 21 days and desired indicators were measured. After exposure to silver, various lesions have been observed in the tissues, that most important of these are the following: epithelial lifting, shorting and collapse of secondary lamellae in gills, nucleus degradation and necrosis and hypertrophy of hepatocytes in the liver and also destruction of the structure of intestinal villi. Results of this study showed that long exposure with silver NPs, caused significantly increase Hsp70 gene expression and after exposure of common carp with silver nitrate, Hsp70 greatly increased however, in term of gene expression, there was no difference between two genes. Also, the most effects observed among the tissues studied in this study were observed in the liver of fish exposed to two forms of silver and at the highest concentration and there was no difference between the two forms of silver in term of toxicology.

In this study, effect of different carbon sources (carrot pomace and molasses) on total bacterial count and histology of intestine in Cyprinus carpio, reared in a biofloc system was investigated. 243 fish (16.8±2.1g BW) were purchased and randomly distributed in 50-liter aquarium (9/aquarium) for 8weeks. Nine different treatments, including a treatment with 100 % daily feeding rate (3%BW) with water exchange as a control, the other 8treatments were assigned to biofloc systems, including treatment 2(100%), 3(75%), 4(50%) and 5(25%) daily feeding rate in addition to carbon source carrot pomace and 4 other treatments, including treatment 6(100 %), 7(75%), 8(50%) and 9(25%) daily feeding rate in addition to carbon source molasses. At the end of experiment, total number of bacteria in the aquaria water and intestine of each fish was counted. Additionally, intestine histology was investigated using H&E. The results showed that there are significant differences in bactria counts of intestine and water between biofloc treatments and control. The highest number of intestinal bacteria (7.7±0.008 logCFU/g) was related to treatment5 and the least of that was observed in control (6.08±0.018 logCFU/g). The highest number of bacteria in water media (6.18±0.023 logCFU /ml) was obtained in treatment6 and the least of that was related to the control (4.18±0.03 logCFU/ml). Significant (p<0.05) increase in villi length was observed in treatment3. The biofloc system and the addition of carbon source caused changes in bacterial count of intestine and water culture media besides alterations in villi length, club shaped cells and leukocytes of carp intestinal.

In 2010-2011 in order to evaluate differences in body shape among populations of chub, Squalius turcicus, De Filippi, 1865 from Tajan, Haraz, Nekarud, Babolrud and Noor rivers of south-eastern Caspian Sea basin 264 specimens were captured by a seine nets. After anesthetizing the samples in 1% clove oil solution and fixing in 10% neutralized formalin, they were transferred to the Isfahan University of Technology Ichthyology Museum (IUT-IM) for further studies. To study the variation of body shape based on geometric morphometric methods, 13 landmarks were defined on the two-dimensional images taken from the left side of samples using the TpsDig2 software. After Procrustes analysis (GPA), digitized data were analyzed using multivariate analyses such as principal component analysis (PCA), canonical variation analysis (CVA) and cluster analysis, also, network deformation changing configuration patterns of population compared to form of the consensus by visualization. The results of this study showed that Babolrud and Haraz populations grouped apart from other populations. Also that the major differences in body shape of the studied populations were related to the head and body depth, and position of the pectoral and anal fins.

The present study was conducted to investigate the effects of diet supplementation with probiotic Lactococcus lactis “subspecies PTCC 1403” on the growth performance and survival rate of grey mullet (Mugil cephalus) for 30 days. The experiment was conducted in a completely randomized design with 450 grey mullet juveniles with average weight of 8.44±1.40g in 5 treatments and 3 replicates (n=30 in each replicate), consisting of two control treatments using non-supplemented food, and three experimental treatments (D1, D2 and D3) which were supplemented with this probiotic with concentrations of 1.5× 108, 3×108, 6×108 CFU /g feed respectively. After 30 days feeding with experimental diets, 10 fish per replication of experimental treatments and one control treatment were challenged by immersion method withlive pathogenic bacteria Lactococcus garvieae (1×107 CFUml-1) for 1 minute and their mortality were recorded for 10 days. The results showed that all of the measured growth parameters and survival rate in treatments containing probiotic improved, but there were not significant differences compared to control group (P>0.05), and only the Condition Factor (CF) parameter in D2 and D3 treatments was significantly different with the control group (P<0.05). Survival percent increased to 64% in D3 and 68% in D2 compared with 40% in the control group (P <0.05). Overall we concluded that the using of this probiotic in the diet of grey mullet could increase survival rates against Lactococcus garvieae bacteria.

The aim of investigation is about the accumulation of heavy metals (Mercury, Lead and Cadmium) in muscle, liver and brain tissues in Neogobius melanostomus from the coast of the Caspian Sea. This research was carried out in 15 samplesduring the year 2015- 2016.Sampling stations were in Sari, Babolsar, Fereydoon kenar, Royan and Ramsar. In order to determine the concentration of heavy metals, Atomic Absorption (A.A.S) and mercury analyzer DMA-80 were used. Cd concentration results in liver 0.33± 0.15and in muscle0.28±0.10 and in brain 0/19±0/05 mg/kg wet weight, Average Pb concentration in the liver was 9.41±1.01 and in muscle10.5±1.89 and in the brain was about 2.18±7 mg/kg wet weight, Average Hg concentration in the liver at various stations was43.10±10.30 and in muscle85.05 ±33.10 and in brain8.24 ±3.07 ug / kg wet net weight.One way ANOVA showed that there was no significant difference between the concentration of mercury in brain tissue and lead in muscle tissue in different stations (p>0.05 ). Pearson correlation coefficient showed that there was a reverse correlation between Cd concentration in liver and muscle tissues and the standard length. The highest accumulation of mercury was observed in muscle tissue and the lowest was in brain tissue. The concentration of lead and cadmium in the target tissues were lower than the standard levels and the concentration of mercury was higher than the WHO1/FAO2 / NHMRC3 / MAFF (UK) 4 standard limits.Person analysis showed, heavy metal (lead, cadmium) in the muscle of "Neogobius melanostomus" was higher and mercury metal was lower than standard WHO1/FAO2 / NHMRC3 / MAFF (UK) 4.

In this study, the histomorphologic differences of the esophagus and intestine between Liza abu as a phytoplankton feeder and Johnius belangerii as a carnivorous was studied.For this purpose, 20 pieces of fish were harvested from any species with the same biometric characteristics from musa creeck. After describtion, tissue samples eere picked up of beginning and end of esophagus, also parts of the primary, middle and end of the intestine. Tissue samples after the usual stages of preparation including fixation in 10% formalin buffer, dehydration with alcohol series, clarification with xylol, paraffin blocking, cutting with 5µ, transfer of specimens on a lam, and coloring, finally examined with a light microscope equipped with a dinolite lens. Results of micrometric studies showed that the esophagus in both species in mucous membranes had multiple folds and its epithelium was squamous with secreted cells. The number of these cells was significantly higher in the end region than to the primary (p≤0.05). Although it was true in primary part for liza abu and end part for Johnius belangerii. From beginning to the end of the intestine it was also increased the number of mucosal cells also the length of intestine villi in the middle part was higher than to the other sections. The length of intestine villi in liza abu in primary, secondry and end was higher than to the Johnius belangerii (p≤0.05). Generally, in histomorphology of the esophagus and intestine of the two studied species, there were differences and similarities in structural that could be affected by how to live and feed.

Livergol drug is made from the herbal extracts of Milk thistle. Milk thistle contains Flavonolignan and has hepato-protective effects. The aim of this study was to investigate the effects of different levels of livergol containing different levels of fat on prevention of liver lesions including water swelling, cloudy swellings, degeneration, fattiness, bleeding and necrosis in Goldfish. For this experiment, 540 Goldfish were used with a mean weight of 3.5±1 gr, which were fed for 90 days with 9 different diets in three treatments 0, 0.2 and 0.5% of Livergol drug and three levels of 9, 12 and 15% fat. At the end of the experiment, samples were collected from the liver tissue and from each treatment four samples were collected for histopathological analysis. The results of the experiment showed that among all the treatments, the most hepatic injuries including water swelling, cloudy swellings, degeneration, fattiness and necrosis were observed in treatment 6 containing 15% fat and without Livergol. In treatment 2 containing 9% fat + 0.5% Livergol, no liver toxicity was observed. The final result of the study showed that the different levels of fat used in this study, the highest hepatic lesions were observed in fish that had 12 and 15% fat levels. Also, in all dietary fat treatments (9, 12% and 15%), the use of Livergol in diet probably due to the presence of Silymarin, reduced liver lesions in Goldfish.

The aim of the present study is to compare the effects of titanium dioxide in nano scale and bulk form in gill, liver and intestine tissues of zebrafish (Danio rerio). In this study About 150 zebrafish exposed to static-renewal condition of TiO2 particles treatment. These nanoparticles and bulk titanium dioxide in concentrations of 1 and 10 mg.l-1 and a blank group in three replicate for 30 days. After the period of treatment (30 days) the fishes were stabilized in formalin and stained for further classic Histological studies. The results indicated that TiO2 in nanoscale and bulk forms can result in epithelium separation, edema, hyperplasia, adhesion in lamella and Hyperemia, hypertrophy in filament of zebrafish (Danio rerio). Also abnormalities as cytoplasmic vacuolization, increase of melanomacrophage centers, congestion and hepatocyte degeneration were observed in liver and injuries such as epithelium separation, increased and inflammation of goblet cells, necrosis and hyperemia in intestine tissue of zebrafish. The findings also suggested that nanoparticles induced more severe abnormalities in comparison with their bulk counterparts. Also, most of the mentioned abnormalities are dependent to the materials concentration. So, the severity of abnormalities was highest at 10 mg.l-1 concentration of the titanium dioxide nanoparticles compared with other treatments.

The aim of this study was improving hematological factors of Blood parrot fish during starvation periods. For this purpose, 200 Blood parrot fish (average weight 25.5±26 g and length 6.34± 0.43 cm( were distributed in three different treatments (two replicates) including 33 fish individuals in each, including control (basic diet), astaxanthin treatment (4g/kg) and astaxanthin-sodium taurocholate, ST (as bile salt) treatment (diet enriched with 4g and 1200 mg/kg of astaxanthin and sodium taurocholate respectively) fed for 90 days and then subjected to starvation for 7 days. Blood were collected at the end of feeding and experimental starvation periods and some haematological parameters were checked. Results showed that main hematological factors (white blood cells counts as exception which increased significantly in fish fed on astaxanthin alone or in combination with ST) were not affected by nutritional treatments at the end of feeding period (P>0.05). After starvation period, Significant decrease in red blood cells counts were observed in fish fed on diet containing astaxanthin alone or in combination with ST (P<0.05). While starvation could significantly reduce WBC only in control fish (P<0.05). Generally, it could be concluded that using astaxanthin alone or in combination with ST as a bile salt in the diet of Blood parrot could not affect hematological parameters the fish after starvation.

The Lauxaniidae with about 1800 described species are one of the large and diverse families of order Diptera. Most species are found in forests, on shrubs, trees, and leaves. Larvae of lauxaniids are saprophagous, having been found in decaying vegetation such as fallen leaves, rotting wood, and bird nests. Before this study 32 species of lauxaniid flies have been recorded from Iran and little information was available on the fauna of Lauxaniidae of Taleghan region. During field studies on lauxaniid flies’ fauna in Taleghan region (Alburz and Qazvin provinces) in 2016–2017 season, a total of 10 species belonging to five genera (Homoneura sp., Minettia fasciata, M. hyrcanica, M. bulgarica, Calliopum caucasicum, Sapromyza afghanica, S. biordinata, S. hermonensis, Eusapromyza martineki and E. multipunctata) are found to occur in this region. Sapromyza hermonensis is recorded for the first time for Iranian fauna. The diagnostic characters of the new record and geographical distribution of the studied species are given.

The present study was carried out during a one year period in 2016-2017 in order to investigation of population fluctuation and biodiversity of soil mesofauna including myripods (Arthropoda: Myriapoda) of forests in Ilam region (Ilam Province, west of Iran). For this purpose, soil samplings were performed from three regions located at different altitudes of Gachan, Manesht and Ghalarang Mountains during different seasons of the year. Soil samples were transferred to the laboratory and myripods were extracted using the Berlese funnel. Totally, 730 specimens of centipedes and millipedes were collected and counted, all belonging to three families Dignathodontidae (Henia sp.), Scolopendridae (Scolopendra cingulata) and Julidae (Cylindroiulus sp. and Amblyiulus sp.). The maximum density of soil myripods in all three areas was observed in the spring; and their population density was higher in Gachan Mountain (147 centipedes / m2, 136 millipedes / m2) than in Manesht (111 centipedes / m2, 128 millipedes / m2) and Ghalarang (92 centipedes / m2, 131 millipedes / m2). In late autumn, population density decreased significantly in all three areas. Based on the results of analysis of variance, the effect of different seasons on population density of myripods in all three regions was significant at 1% level. Given the diverse vegetation in this area, the Shannon-Weiner and Simpson indices were high and optimal in all three areas. The results of Shannon's evenness index also showed that the value of this indicator for millipedes was higher than centipedes in all the three sampled areas. According to this study, myripods are potentially one of the main factors in food chain in Zagros forests and our results show the importance of biodiversity conservation and management of natural resources of this area.

The members of the subterranean genus Niphargus Schiödte, 1849 live in subterranean waters or waters related to subterranean environments, such as springs. This group is one of the most species-rich genera (more than 300 species and subspecies) among freshwater amphipods in the world, distributed in the Western Palearctic. Iran has been recognized as the easternmost border of the genus Niphargus. Until now, there have been 17 species recorded from Iran; of these only one species was found outside Iran (N. valachicus), all other species are endemic to the country. In this study, the diversity and distribution of the Iranian niphargids are surveyed and contributions are made to diagnostic characters for each species and one new record of N. hosseiniei in Bilvar village in Kermanshah Province is reported. The distribution map of species localities were created using Arc GIs. Noteworthy, most of the Iranian species were described during the past five years and additional species descriptions can be expected to the subterranean fauna of Iran in a near future.

The effects of Microcapsulation oil on growth factor and body proximate composition of the giant fresh water prawn and some physical qualitative factors of its pellet were investigated. For this purpose, 6 pellet treatments with isoproteic 33 percent were prepared. Three level of fat 6, 9 and 12 percent were considered that tow diets made at each fat level. In one of the diet (1, 3 and 5) oil was not microcapsulated and microcapsulated in other diet (2, 4 and 6). In 12 percent lipid level, weight gain and feed conversion ratio were significantly different (P< 0.05) in treatment without microcapsultion oil (5) and microcapsulated oil treatment (6). Also specific growth rate and protein efficiency ratio was significantly (P< 0.05) higher in 6 diet than to 1 and 2 diets. In growth factor, effect of lipid level was significant but microcapsule effect and interaction were not significant. The microcapsulation in diet 12 percent lipid level cased to significant (P< 0.05) increase in fillet fat and also in effect of lipid level and microcapsule effect. In physical qualities of pellet like durability, fat leaching, density and sinking velocity were significantly (P< 0.05) influenced to microcapsulation, especially in diets with 9 and 12 percent fat level. In conclusion oil microcapsulatin in 6 percent lipid level was not significant on growth factor, fillet fat and physical qualities of pellet.

The oriental river prawn (Macrobrachium nipponense) is a widely distributed non-indigenous species to southern Caspian basin-northern Iran. This research aimed to study its growth and mortality characteristics using 860 specimens in Boustan Dam Lake located in south-eastern Caspian Sea form February to September 2016. Male to female ratio was 1:1.11. Differences in shrimp abundance and total weight were significant among various months (p<0.05). The range of total length and weight were 11.7-74.94 mm and 0.04-4.51 g respectively. Mean length and weight of males (40.24 mm and 0.81 g) was less than those of females (41.7 mm and 1.01 g). The relationship between length and weight of males and females was significant in Boustan Dam Lake, both genders had an isometric growth pattern. Growth parameters were estimated as L∞=86.63 mm and K=0.79 for males, and L∞=76 mm and K=1 for females. Natural mortality of males was 1.08 and that of females 1.17. Based on the results of the present work it seems that Boustan Dam Lake has suitable condition for growth of M. nipponense.

Cathepsins represent a major component of the lysosomal proteolytic system and, as such, are responsible for intracellular protein degradation. The aim of this study was to evaluate the cathepsin-L (CTSL) gene expression changes and growth factors in Litopenaeus vannamei under various biofloc systems (BFT) and different protein levels. Four bioflocs were used: BFT fed diets of 25% CP and spoilage palm date extract (P25), diets of 25% CP and molasses (M25), diets of 15% CP and spoilage palm date extract (P15), diets of 15% CP and molasses (M15) and clear water without biofloc fed with 38% CP (Control) that were performed in triplicate. A 35-day study was conducted with 35 juvenile (average 5.37±0.33 g) shrimp randomly stocked in fifteen 300 L tanks at a stocking density of 175 shrimp m−3. Real time PCR technique was used to estimate the effect of biofloc on the CTSL gene expression in shrimp hepatopancreas and Beta actin gene was used as an internal control gene. In all the biofloc treatments, a significant increase in the expression of CTSL gene was observed (P <0.05), although P25 had the highest expression (P> 0.05). Moreover the highest growth parameters (weight gain, better feed conversion ratio (FCR), growth rate and survival) was showed in P25 and the lowest in the control (P <0.05). The results showed that there were no significant differences in the expression of CTSL gene in change of carbon sources or dietary protein in the biofloc treatments (P> 0.05). It seems the biofloc technology with its positive effects on digestion and immunity provides the basis of increasing the CTSL gene expression in this species.

In this study, the identification and biodiversity of macrobenthos of Jajrood and Karaj protected rivers which provide a large portion of Tehran's drinking water, have been studied simultaneously for three consecutive years. Physicochemical and macrobenthos samples were collected with three replications, during three consecutive years from 19 stations with a Surber sampler. Statistical analyses were done by SPSS, Past and R softwares. In Jajrood River, 6667 macrobenthos in 22 families and in Karaj River, 13,246 macrobenthos in 24 families were identified respectively .The highest abundance and diversity of macrobenthos and the most appropriate time for sampling was in summer. The results of CCA showed that physicochemical parameters TSS, EC , DO and pH had the highest effect on the distribution of macrobenthos. In Jajrood River, Baetide and in Karaj River Simullidae are the most dominant families. The Simpson dominance index in both rivers tends to one and indicating the high frequency of one or more families compared to the others. The mean values of Shannon-Wiener (H) index varied in the four sampling periods in Karaj River between 2.04± 0.11 to 2.5 ± 0.06 and in Jajrood River between 1.4 ± 0.22 to 2.4± 0.42. Both Rivers are similar in terms of macrobenthos fauna and biodiversity. Results of biodiversity indices showed that human activities affect macrobenthos communities and the most negative effect on the ecosystem of the two rivers is due to tourism activities, Recreational use and land use changes.

Ongoing ecological study of the Caspian Sea, in particular distribution, identifying the species composition and regional variations, seems to be necessary before any study. In order to, in present study, the replacement of benthic groups in the Gorgan Bay and southeastern basin of the Caspian Sea (Golestan province) was studied and compared with the results obtained in previous studies. The results of the study of benthoses showed that the polychaete worms, oligochaete worms, nematodes, chironomidae worms, bivalvias and amphipoda crustaceans constitute the main benthic founa of the ecosystem. These results indicate a very inadequate quality status in the studied areas. The results of the comparison with other previous studies also showed that factors such as the input of organic and inorganic pollutants, inappropriate disposal of wastes, the closure of the main channels of the Caspian Sea and the lack of ventilation of the ecosystem, the construction of inappropriate fishing facilities and etc. caused the hypertrophy conditions and a significant reduction in density and diversity of benthoses in these areas.

Aquaculture is one of the human activities in which uncontrolled development has negative effects on the environment and biomonitoring can be used to explore it. In this study, the environmental impacts of shrimp farms effluents on macroinvertebrate communities in Gomishan Wetland were investigated. Sampling was performed from six stations monthly for one year and five biological indices were used to investigate the quality status. The results showed that the average density of macroinvertebrate communities was 31934 individual/m2 and the most frequent family was Pyrgulidae. The maximum density among stations was observed in Gorganrood River mouth station. The comparison of density in different months showed that in the first three months of the year, the it was higher than the others; Then, the frequency decreased in summer. Along with the depletion of shrimp farms effluents into the Gomishan Wetland in August, the average abundance of macroinvertebrates increased, but it reduced again in the last four months of the year. The Margalf and Shannon-Weiner indices in different months and stations indicated pollution in this wetland. By calculating the Simpson index, it was found that by increasing the pollution, along with the reduction of water volume, the distribution of macroinvertebrates became more uniform. Pielou index with the mean of 0.4 showed no significant differences between different stations and months. Also, the study of distribution index confirmed the clumped distribution. The water quality in Gomishan Wetland was undesirable, indicating the necessity of effective management policies to improve the water quality in this international wetland.

In this study, a discriminant analysis was carried out to compare the morphological variation among the Indian squid (Uroteuthis duvaucelii) collected from four regions in the Persian Gulf and Oman Sea (two regions in the Persian Gulf (Bushehr waters and Western Strait of Hormoz) and two regions in the Oman Sea (Sistan and Balochestan waters and Eastern Strait of Hormoz). The most important variables were investigated factor analysis with principle component analysis (PCA). Indian squids were sampled by stern bottom trawlers and further 21 morphological factors were investigated. The results indicated that in the main component analysis, two components were formed, the first and second components contains 54.24 and 81.50 % of the total variance respectively. The second component consists of four arms in the U.duvaucelii. Investigating the difference between groups by discriminant analysis method showed that three functions were formed (P<0.05) and based on U.duvaucelii from the four regions can be divided into three groups, two inhabiting in the Persian Gulf, and one group in the Oman Sea.

The aim of this study was to measure the concentration of the acetylcholinesterase (AChE), glutathione S-transferase and catalase as biomarkers of heavy metal contamination in pearl oyster Pinctada radiata and their mechanism in aquatic ecosystems. Heavy metals lead, cadmium and nickel were measured in soft tissue and studied stations in two seasons. Samples were collected seasonally in Lavan stations, Hendurabi and Nakhilo (in the northern Persian Gulf) from spring 2013 to winter of that year by scuba diving. Pearl oysters are divided according to their shells size; shells separated from soft tissues and were transferred to the laboratory for analysis of heavy metals and enzymes. Moopam standard method were used for measuring the concentration of heavy metals and for analyzing tissue concentrations of glutathione S-transferase in Clam the method recommended by Habig et al In 1974 were used. For measuring acetylcholinesterase Ellman method were used. Catalase contamination in pearl oyster in the supernatant obtained from the study based on the method homogeate soft tissue of mussels which Abeiwere evaluated. The concentration analysis of heavy metals nickel, cadmium and lead in the soft tissue of Pinctada radiata in all three stations, respectively 0/12 ± 0/58 and 1/86 ± 0/04 and 1/94 ± 0/30 in parts per millionThe, concentration of acetylcholinesterase at several stations, in large and small sizes and in the seasons had no significant difference. Variations of catalase, and glutathione S-transferase were almost similar to each other and parameters, station and seasons were significantly different in the concentrations of these enzymes. Seasonal changes in antioxidant enzymes related to (assuming a constant in salinity and oxygen) to age, reproductive cycle, and availability of food and water temperature. With increasing temperature at warm season, antioxidant enzymes were increase, with increasing temperature and abundance of food in the environment the amount of antioxidant enzymes may increase. The presence of the enzyme concentration may indicate that the higher levels of the enzyme to eliminate ROS activities to be any healthier situation. At the time of gonads maturation and spawning season catalase activity increases. This study also indicates that catalase was significantly higher in the warm season. Due to low pollutants of heavy metals in the study area, a lower level of contaminants were observed in shellfish tissue incidents of international standards and strong correlation between the amount of heavy metal contamination in pearl oyster tissue and enzymes was not observed, Therefore, we can say that the pearl oyster remains in a healthy condition and the amount of enzyme is normal.

Nais variabilis is cosmopolitan oligochaete worm and is common to fresh and brackish water habitats. This species has not been reported from Iran freshwater fauna and South Caspian Sea before and it was found while investigating limnology of Cheshmehkileh and Sardabroud rivers and estuaries alongside the Iranian coasts. Nais variabilis was collected bimonthly from November 2014 to September 2015 using a Van Veen grab (0.03 m2) and Surber (0.1 m2, 0.2 mm-mesh size) with three replicates at 6 stations. Results of temporal distribution showed that the highest and lowest density and biomass of this species were in November (118.8 ±79.8 ind/m2 and 0.075 ± 0.034 gr/m2) and in September (26.5 ±9.8 ind/m2 and 0.015 ± 0.005 gr/m2) respectively which were significantly different (P<0.05). Among sampling stations, freshwater stations (S1) within the river showed higher density and biomass (139.4 ± 83.3 ind/m2 and 0.08 ± 0.029 gr/m2) than brackish stations (S2) (21 ±10.6 ind/m2 and 0.015 ± 0.006 gr/m2) and marine stations (S3) (0 ±0 ind/m2 and 0 ± 0 gr/m2) which were significantly different (P<0.05). Density and biomass of this species in Cheshmehkileh River and estuary was more than Sardabroud. A significant correlation (P<0.05) between the density and biomass of N. variabilis and environmental variables were found.

Climate change and human activities have, over the years, resulted in the loss and reduction of the level of coral ecosystem coverage and the reduction of the effectiveness of conservation and rehabitation projects. So, it is necessary to use technologies such as biorock to increase the growth and survival rate of corals. In this regard, the effects of using biorock method on the growth and survival of coral (Acropora calthrata) in the Chabahar Bay were evaluated. Coral pieces were placed on steel structures under a 6V electric field in the biorock process. The coral growth, growth performance and survival rates of corals during the twenty-eight weeks were studied. The mean coral growth in the biorock structure was 12 ± 0.29cm and the mean coral growth was 5.25 ± 0.23 cm in the non biorock structure. The results show a significant difference between coral growth in the biorock with non biorock structures (p <0.05). The results of this survey on the growth rate of Coral (A. calthrata) in the biorock structure compared to the control structures showed a two-fold increase in growth and a higher survival rate. The results of this study indicated that stimulation of coral (A. calthrata) growth by biorock method could be use biorock technology to stimulate coral growth and survival in protection and rehabitation program.

The presence of a large number of microorganisms has been proven in many species of sponges. The purpose of this study was to determine the antifungal properties of sponge associated bacteria, which so far has not been reported in Iran. For this aim, the mesohyle tissue of Haliclonia simulanse sponge obtained from coastal waters of Bushehr Province was inoculated with appropriate dilutions in culture media. At primary screening, eight strains were obtained. To determine the antifungal properties of isolated bacteria, two methods consist of diffusion of disk and disk agar against 3 strains of fungi Rhizoctonia solani, Penicillium italicum and Fusarium oxysporum were used. In order to determine the compounds in methanol extract of strain number 4 GC-MS was performed. The molecular identification of strains 4 and 7, which had the highest antifungal properties, indicated that strain 4 had the most similarity of 98% with Bacillus sp. (With a genetic distance of 0/004) and strain 7 has the highest similarity of 95% with Staphylococcus haemolyticus (with a genetic distance of 0.02). Strains 4 and 7 were registered at NCBI with access numbers KY31376 and KY71394, respectively. In disk agar method, the highest antifungal effect belongs to Bacillus sp. that produced a no-growth field with a diameter of 28.38 mm against R.solani. Staphylococcus haemolyticus showed the highest antifungal effect against F. oxysporum with the creation of an inhibition zone with a diameter of 27.41 mm. In the disc diffusion method, methanol extracts of Bacillus sp and Staphylococcus haemolyticus had the most anti-fungal effects.

One of the problems with Pseudomonas aeruginosa-related infections is prevalence of Multiple-Drug Resistant isolates. Bacterial efflux pumps are capable of a wide range of antibiotics and detergents to efflux out of the cell. The aim of study was determining efflux pumps activity in fluoroquinolones resistant MDR strains of Pseudomonas aeruginosa. 50 strains ofPseudomonas aeruginosa were isolated from clinical specimens of patients were admitted to Milad hospital and diagnosed by biochemical tests. Antibiotic susceptibility was determined by disc diffusion method according to CLSI. After determining the MDR isolates, for evaluation of efflux pump activity the MIC of ciprofloxacin, levofloxacin was determined before and after treatment by CCCP inhibitor. 17(34%) MDR strains of Pseudomonas aeruginosa that were resistant to more than two classes of antibiotics were detected. Among flouroqinolon MDR strains of Pseudomonas aeruginosa 2 (11.8%) and 3(17.64%) had MIC reduction of at least 4 times and more for ciprofloxacin and lovofloxacin after carbonyl cyanide-m-chlorophenyl hydrazone (CCCP) effect, respectively. The frequency of MDRPseudomonas aeruginosa are low. Only 4 isolates among MDR bacteria had efflux pump activity. So the efflux pump is not major mechanism for resistance to ciprofloxacin and lovofloxacin among these isolates and further studies about other resistance mechanism is recommended.

Acinetobacter baumannii is the important cause of nosocomial infections worldwide due to its propensity to rapidly acquire resistance determinants to a wide range of antibiotics and is the major of Multidrug resistant bacteria. There are many different mechanisms for occurrence of MDR in A. baumannii isolates that efflux pumps, beta-lactamases, integrons, insertion sequence(IS) and structural proteins. 79 strains of Acinetobacter baumannii wereisolated from clinical specimens of patients were admitted to Hearth Tehran hospital and diagnosed by biochemical tests. Antibiotic susceptibility of isolates was determined by disc diffusion method according to CLSI 2015. Finally, DNA were extracted and presence of adeA, adeB and adeC genes was evaluated by PCR. The resistance to amikacin, ceftazidime, ciprofloxacin, meropenem, imipenem, tetracycline and trimetoprim were 83.75%,86.25%,82.5%,86.25%,91.25%, 58.75%t 93.75% respectively. The frequency of adeA,adeB was similar 96.2% and for adeC gene the frequency was 91.1 % .There was a significant relationship between imipenem and meropenem resistance and frequency of efflux pump genes. According to high prevalence of AdeABC efflux system genes may be play an important role in antibiotic resistance of A. baumannii clinicalisolates specially imipenem and meropenem resistace. Althouth it must be mentioned the role of efflux pumps gene expression in antibiotic resistance.

Caspian red deer or maral (Cervus elaphus maral) is a ruminant from the family of cervidae. Maintenance and protection of maral requires knowing the behavioral, physiological, environmental characteristics and factors harmful to this species. In this article, reproductive and behavioral traits of this species in both sexes are presented based on observations and the available records of protected deer in Wildlife Refuge of Semeskande, Sari from 2006 to 2011. Hart characteristics including sexual behavior, apparent changes during reproductive season and reproductive physiology; and hind characteristics including of ovulation, reproductive cycle, mating, pregnancy and parturition, have been evaluated. Identification of maral reproductive characteristics in Wildlife Refuge of Semeskande, Sari is one of the most important information requirements to preserve and breed this species and will open up new routes for performing new methods of reproduction of this species in Iran wildlife parks or other refuge areas.
