The brown bear populations, contrary to other mobile carnivores, exhibit a worldwide genetic structure in several mitochondrial lineages. Populations of the Middle Eastern brown bear, including Iran, are at risk of local extinction. Genetic relationships between the Iranian brown bear and others in the world are still unclear. We sequenced a 614 base pair fragment of the mtDNA control region for 50 brown bears from Iran. The Iranian brown bear presents considerable haplotype diversity (50 individuals, 22 new haplotypes). Mitochondrial sequence analyses revealed one new major mtDNA lineage within Iranian brown bears, comprising 2–3 subclades: (i) Alborz, which includes bears from the Alborz and the Arasbaran Mountains; (ii) Zagros, including individuals from south of East Azerbaijan province to the Southern Zagros Mountains (Kazeroun, Fars province); and (iii) Fars, which comprises bears living in the Southeastern Zagros Mountains (Marvdasht-Eqlid, Fars province). The results of fixation index (FST) and analysis of molecular variance (AMOVA) demonstrate significant genetic structure among the Iranian subclades. Overall, the Iranian brown bears show significant geographic structuring, in addition to the remarkable haplotype diversity.

Detecting parameters influencing habitat suitability is crucial for conserving and managing rare and valuable species. Suitable habitats play prominent role in survival and reproduction of species, therefore they are considered in wildlife conservation. In this study presence data of Iranian Cheetah (Acinonyxjubatusvenaticus) as a critically endangered species, which had been collected in Naybandan wildlife refuges ince autumn 2009 until autumn 2011; were scrutinized via Ecological Niche Factor Analysis approach in Biomapper software in order to mapping habitat sustainability and recognizing habitat requirements. After generating maps by means of Biomapper and Idrisi software, layers of habitat parameters including elevation, slope and aspect, vegetation cover, distance from water sources and distance from ranger stations were imported in Biomapper. The output scores obtained from the analysis shows that Iranian Cheetah prefers mountainous areas with more topographical features for camouflage in order to hunting preys; likewise northern aspects with more humidity, denser vegetation cover and more preys is most preferred. According to our results Iranian cheetah has medium niche width in Naybandan wildlife refuge and favours marginal habitats.

In this study, records of 7 herd first lactation dairy cows were used. Data was collected from 2003 to 2013 by Aria Delta gene and during this study were evaluated. Traits in this study included production (milk, fat, protein yield), type (body depth, angularity, support udder, , fore udder attachment, udder depth) and reproductive (open days and age at first calving) and length of productive life traits. Data analysis was performed by restricted maximum likelihood procedure using wombat software. Heritability estimates of milk, fat, protein yield, , 0.28, 0.49, 0.42 and heritability of age at first calving and open days 0.69, 0.07 and heritability of body depth, angularity, support udder, fore udder attachment, udder depth, respectively, 0.27, 0.25, 0.12, 0.05 and 0.36 respectively and heritability was estimated length of productive life 0.2. . Genetic correlations were between milk and fat yield and genetic correlation between milk and protein yield 0.12 and 0.05 respectively. Genetic correlations between of open days and age at first calving traits 0.21 respectively. Genetic correlations among type traits in the range of -0.51 to 0.72 and phenotypic correlation between type traits in the range of -0.19 to 0.22, respectively. The greatest positive genetic correlation was estimated between body depth and angularity 0.7 and the highest negative genetic correlation between the body depth and udder depth -0.51. The estimated genetic correlations between production, reproductive and length of productive life traits ranged from -0.51 (length of productive life traits and protein yeild) to 0.63 (age at first calving and fat yield). Considering negative genetic correlation between production and reproduction traits, planning of selection programs in dairy cows based on a combination of production and reproduction traits is recommendable. Genetic correlations variable among type traits and longevity in the range 0.01 to 0.39.

A present study was carried out to determine the effects of replacing guar meal with soybean on blood parameters and milk production factors of Holstein dairy cow. Experiments were conducted in two stages to compare the nutritional quality of guar meal with soybean meal in diets of Holstein cows. In the first stage chemical composition were evaluated for two this meals. In the second stage meal effect were examined on the parameters of feeding behavior, and blood metabolites and milk production of lactating Holstein cows. Eight Holstein cows were selected based on milk production of 305 days ago, parturition and the expected date of birth for the second step of test and randomly divided into two groups, 4 cows in each group. Selected cows were fed with feed containing protein and energy the same treatment containing 15% soybean meal (without the use of guar meal) and two treatments with 15% guar meal (without the use of soybean meal) from 5 to 56 days postpartum. Crude protein, crude fat and ash guar meal was lower than soybean meal, but the ADF and NDF in soybean meal was higher than guar meal. Based on results, there was not observed significant difference between plasma glucose cattle (0.05 <p) but minor differences was observed between two treatments. Blood glucose increased in 15% guar meal treatment compared to the other treatments. Effects of treatments did not caused significant difference between plasma amylase aspartate enzymes between treatments. However, guar meal treated 15 percent to control gender was an increase in the number of these enzymes. Statistical analysis of the data showed that the treatment with the lowest fat percentage has a positive relationship with milk protein synthesis. But statistically, in the daily production of milk were observed significant differences between treatments. Based on results of this study, guar meal is a suitable alternative for protein.

Captive breeding is conducted to increase the populations of a species and to re-introduce them to the wild, it is also of importance for species conservation. Here, we aimed to assess the taxonomic status and genetic diversity of the sheep population in Chadegan recreation village, using a fragment of 688 base pairs of Cytochrome b gene. Results showed that the captive bred population of Chadegan recreation village belonged to O.vignei and the subspecies of O.vignei laristanica. Three new haplotypes were identified in the current study and added to the previous 67 haplotypes, which show a relatively high genetic variation in the Chadegan population. The genetic divergence within and between O.vignei, O. orientalis, O. canadensis and O. ammon was calculated using K2P method. Minimum and maximum intra-specific genetic distance within O. vignei were obtained from 0.013 to 0.015 while the inter-specific genetic distance between O. vignei and O. canadensis ranged from 0.086 to 0.088 and the distance between O. vignei and O. orientalis varied from 0.021 to 0.24. The lowest intra-species genetic distance was observed between subspecies of O. canadensis and O. orientalis while the maximum value was obtained in O. vignei subspecies. Considering the genetic distances that exist between the subspecies, transferring individuals between populations should be performed with adequate care to preserve the intra-specific diversity of wild sheep.

The mouse-tailed bats genus Rhinopoma traditionally are considered as one of the most ancient living microchiropteran clade. The species of this genus inhabiting arid and subtropical regions of the Old World including North-western Africa, Middle East, Levant, Iraq, Iran, Pakistan, Afghanistan, India, Thailand and Sumatra. Mitochondrial D-loop gene was used for phylogenetic relationship in this genus. In this study we collected 36 samples from different localities for DNA analysis. After amplification and sequencing of sightly fragment, the sequence lengths were 577 bp and the mean base composition was: A (35.23%), C (24.16%), T (28.60%), and G (12.01%). From 577 sites, 168 polymorphic sites were recorded that 148 from one were parsimony informative. Results showed that genus Rhinopoma in Iran includes three species (eg. R. microphyllum, R. muscatellum and R. hardwickei). Also, phylogenetic survey showed that the sister status of the R. microphyllum and R. muscatellum phylogroups contradicts with traditional arrangements of the family where R. hardwickii and R. muscatellum are considered as the most closely related taxa based on similarities in narial morphology and body size.

Ghrelin exerts inhibitory effects on hypothalamus- pituitary- gonadal(HPG) axis. Aromatase is a key enzyme in the steroidogenesis pathway and it converts testosterone to the estradiol in the brain. In the present study the effects of the injection of ghrelin was investigated on aromatase gene expression in the hypothalamus of androgenized female rats. Twenty female Wistar rats were androgenized on the third day after birth by subcutaneous injection of 50 microgram testosterone propionate. Adult androgenized animals received third cerebral injection of saline, 2, 4 or 8 microgram ghrelin respectively. Also, five adult non-androgenized rats received third cerebral injection of saline as control group. The hypothalamic level of aromatase gene expression was determined using semi-quantitative PCR. Mean aromatase gene expression increased significantly in the hypothalamus of the androgenized rats compared to controls. Ghrelin decreased significantly aromatase gene expression compared to the androgenized rats. Ghrelin may inhibit the expression of genes involved in the steroidogenesis.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorders that affects approximately 5-10% women in their reproductive age. It is characterized by endocrine anovulation, hyperandrogenism and insulinresistance. Nigella sativa (NS) grain has a rich medical and religious history and consists of powerful chemical compounds that can have many effects on human health. In this study the effect of Hydro-alcoholic extract of Nigella sativa on antioxidant properties of the ovary tissue in a rat model of PCOS has been investigated. For this purpose, 32 mature female rats were randomly divided into 4 groups as: Control, PCOS-induced (received 4mg estradiol valerate, IM), PCOS+NS (200 mg/kg B.W-1)-treated and PCOS+NS (600 mg/kg B.W-1)-treated. Animals received NS orally by gavages for 63 days. After 63 days, the animals were sacrificed in the estrous phase and MDA and TAC were measured in ovary tissue. This study showed that Nigella sativa compared to the PCOS-induced group thereby increasing the TAC and decreasing MDA. And from the used doses the dose of 600mg/kg/bw had the most positive impact. So Nigella sativa has marked antioxidant activity; therefore, it can reduce the amount of stressoxidative.

This study was carried out to investigate the waterbird community parameters, such as abundance and diversity indices at Hormozgan province eastern wetlands in 2015. In order to perform this study, bird observations at 22 wetland sites were conducted and categorized using direct observation and totally count method by binocular and bird watching telescopes. Furthermore, species diversity, evenness and richness indices were calculated using the Shannon-Wiener’s H, Simpson’s D,Margalef's D, Pielou J′, Brillouin (E), McIntosh (E), and Species Abundance (N)indices. A total of 44582 individuals representing 68 overwintering species from 17 families were recorded. The Cormorant (Phalacrocorax carbo) and Dunlin (Calidris alpine) were the most abundant species with 20.71 and 11.13% individual observation, respectively. The results of observations showed that the estuaries of Tyab and Meydani hosts the largest number of waterbirds overwintering with 15.26 and 13.66% totally observations, respectively. The highest species diversity were observed in the Mudflats of Bandar Abbas (3.07) and Surgalm (3.03), while Jask Bay (1.64) and Behel coast (1.3) had the lowest number of species diversity. Moreover, the highest species richness were obtained at Khour-e-Namaki (5.44) and Mudflats of Bandar Abbas (5.19). While, the lowest species richness were obtained at Nakhl-e-Ebrahimi (1.49) and Abd-Sedij coast (1.42). Surveys show that the use of both habitats including mudflats and mangrove forest, plays an important role for bird habitat selection. In terms of total species diversity of wetland areas in the east of Hormozgan province, Shannon-Wiener, Simpson and Margalef indices were calculated to be 3.12, 13.20 and 6.26, respectively. Moreover, for total species evenness, Pielou, Brillouin and McIntosh indices were calculated 0.74, 0.74 and 0.82, respectively. At the end, the study showed that due to the importance of eastern wetlands of Hormozgan province for wintering of waterbirds, wise development strategy seem to be inevitable.

Birds and environmental variables were recorded within a 25 m radius of each of 122 sampling points. To determine the bird species density and association between environmental variables and bird community, distance sampling method and Redundancy analysis was performed, respectively. To determine the association of bird diversity indices with environmental variables, the Redundancy analysis (RDA) was performed. In the period of the study a total of 216 birds, 14 species, were recorded. In gap area, Great tit (Parus major) , Blue tit (Parus caeruleus), and Robin (Erithacus rubecula) had the highest density, and Black woodpecker (Dryocopos martius), Wren (Troglodytes troglodyte), and Spotted flycatcher (Muscicapa striata) had the lowest density. In canopy closed area Great tit, Blue tit, and Robin had the highest density, and Blackbird (Turdus merula), Coal tit (Parus ater) and Spotted flycatcher had the lowest density. The values of 2, 0.5, and 0.6 were respectively recorded for the number of dominant species (N2), Shannon diversity index and Camargo evenness index. These indices had the highest values in canopy closed areas. The results of this study highlighted the importance of canopy closed areas for conserving and enhancing of birds especially in Golestan National Park.

The Study of changes in species diversity and abundance of wetland bird populations, as the most important and most vulnerable environmental resources of the world, is a suitable biological agent to explain the quality and health trend of these ecosystems. The objective of this research was determining the areas in the deltas of Rud- e- Shur, Rud- e- Shirin and Rud- e- Minab International Wetland, which have diversity and richness of waterbirds; by using echelon software based on the spatial structure analysis. For this purpose, In January 2013 and 2014, three observers identified and recorded the location of birds with a GPS device, and for counting and determining the population size of birds used Swarovski and Zeiss binoculars (20x60 zoom eyepiece) and a counter was used to count large populations easily.
Then the area was divided into cells with areas of 9 and 36 km2 and for each cell the number of observed species was recorded. The calculation of richness was done based on species, genus and family to consider phylogenetic preferences in the area richness too. In this study the total number of migratory birds was recorded 36741 individuals, include 80 species, 45 genera and 23 families. Based on the net which had 9 km2 cells, 12 cells with an area of 10800 ha and 46 cells with an area of 41400 ha were defined as safe zone and second zone, respectively; and providing the net had cells with an area of 36 km2, 7 cells equivalent of 25200 ha and 20 cells equivalent of 72000 ha identified as safe zone and second zone, respectively. The comparison between two methods showed that the nets which had cells with smaller area, had higher accuracy in separation of high species richness of areas; while the nets which had cells with bigger area, provided an appropriate general view of areas for us.

Birds as a vertebrate which showed a high variety of sounds have a specialized organ sound production, the syrinx. Muscicapidea as one group of Songbirds of Passeriformes are seen in the diverse habitats which have a high ability not only in learning but also in imitating sounds. Surely acoustic studies beside the molecular studies would be useful for clarifying the phylogenetic relationship among the members of this problematic family. In this study, we analyzed the Song of 40 species of this family using Raven Pro version 1.5 software. For this dataset seven vocal characters were defined and finally the NJ and UPGMA were constructed using the Phylip 3.60 and PAUP 4.0 software respectively. The results almost demonstrated total incongruence between vocal and molecular phylogeny. In general, we find 62 and 45 percent congruence between constructed tree of NJ and UPGMA and accepted molecular phylogeny respectively.

This investigation was aimed to study polymorphism of PIT1 and STAT5B genes and their association with growth and carcass traits in Mazandaran native fowl. For this purpose, 200 sexed male chicks of Mazandaran native fowls reared in the same conditions and all were slaughtered at 12 weeks of age. Traits before and after slaughter including live weight at 4, 8 and 12 weeks of age, body weight, heart, liver, gizzard, spleen, abdominal fat, meat pH, water holding capacity of the meat and intramuscular fat were measured and recorded. Before the destruction of all birds, blood samples were collected and extraction of DNA from samples were performed by Cinnagen kit. Then, the desired locus of each gene was amplified using specific primers and genotyped using PCR-RFLP method by specific enzymes. The frequency of each allele (+) and (-) were determined 0.715 and 0.285 in PIT1 locus and 0.355 and 0.645 in STAT5B gene locus, respectively. Phenotypic and genotypic data analysis using SAS9.12 statistical software showed a significant association between PIT1 genotypes and live weights at 12 weeks of age, carcass weight and liver weight and also STAT5B genotypes with live weights at 8 weeks of age and abdominal fat (P <0.05). Therefore, it can be concluded that PIT1 and STAT5B genes can be used as candidate genes for growth and carcass traits in Mazandaran native fowls breeding programs.

The experiment to investigate the effect of different ratios of copper and zinc in the diet on the performance of quails was conducted under heat stress. A total of 144 chicks of 10 days from the Japanese race were reared for 47 days. The experiment in a completely randomized design with 6 treatments and 4 replications of 6 broilers each category. . Treatments, normal control groups under stress (Cu 1.5 to 88), copper lower than control (0.75 and 88), more copper than controls (3 and 88), on less than controls (1.5 and 44) on more than controls (1.5, 176), respectively. The results show that the control group and the less stress from witnessing the highest weight gain than the control group was normal and of course, between these two groups, control stress better effects as weight gain was higher (p<0.01). The intake of more copper than the control group compared to the control group was normal (p<0.05). The feed efficiency of the Group of copper is higher than the normal control group compared to controls (p<0.01). Among the traits of carcass traits only have significant heart (p<0.05) were higher than the control group than the control group with the lowest weight of the heart is normal. In conclusion, we have better effects than the control group, and as Copper was the best treatment.

Sexual dimorphism (SD) is changes in body shape or size between the two sexes. SD is a common phenomenon in lizards, even observed among populations of the same species occupying different habitats. The Bedriaga’s Skink Gecko, Teratoscincus bedriagai, belonging to the family Sphaerodactylidae, is a nocturnal species which has been distributed in northern and eastern desert basins of the Central Plateau of Iran. A total number of 30 adult specimens (15 males and 15 females) of T. bedriagai were collected from April to August 2013 from four stations in southern parts of Damghan County, Semnan Province. All the specimens were collected at night using a torch, transferred to Zoological laboratory of Damghan Branch, Islamic Azad University. After anesthetizing the specimens, ten metric and meristic characters were measured. Statistical analyses were done using SPSS 18. The results of present study show that males and females of T. bedriagai are not significantly different (p < 0.01) in metric (body weight and length, tail length, head length, head width) and meristic (right and left supralabial and infralabial scales, and scales around the mid-body) characters.

The aim of this study was to investigate the effects of Sodium propionate on some hematological parameters (white and red blood cell count, hemoglobin, hematocrit, MCHC, MCV and MCH) and biochemical indices (glucose, cholesterol, albumin and total protein) in common carp. Fish with an average weight of 25.99 ± 4.43 gr divided in 3 treated groups, fed 0.5, 1 and 2% of Sodium propionate supplementation and the control group (in 3 replicates). According to the result adminestration of diet with Sodium propionate showed no significant increase in hemoglobin, hematocrite, MCHC and MCV in some treatments, however MCH, red cells and white cells showed significant increase in fish fed supplementation of 1%, 2% and 0.5 and 1% (p<0.05). Result also showed a non significant decrease in Cholesterol levels (p>0.05). A significant difference was seen in glucose level among treatments. The lowest level of glucose was seen in 2% propionate. Fish were fed with supplementation of Sodium propionate didn’t show significant difference compare with control group (P>0.5). It appears that supplementation of food with Sodium propionate could improve immune parameters in common carp.

Rainbow trout (Oncorhynchus mykiss) has great importance in terms of meat quality, easy reproduction and sport hunting and is the most important species of salmonides in freshwater. This research was carried out to determine the effect of thermal stresses on some hematological factors and gill tissue in rainbow trout on 300 fish. For this purpose, fishes that have weight of 30 gr selected randomly and were in 5 treatments (Each treatment has three replicates) and these were treatment 1 (control): 14 °C, treatment 2: 28 °C, treatment 3: 25 °C, treatment 4: 20 °C and treatment 5: 5 °C. This action did for 24 hours. The results showed that the highest number of RBC, the highest number of WBC, the highest number of hemoglobin and hematocrit and the lowest levels of glucose and cortisol were in treatment 1 (control), treatment 5, treatment 1 (control) and treatment 1 (control) (P< 0.05). There were no significant differences in other hematological factors (MCV, MCH, MCHC, neutrophils, lymphocytes, monocytes, and eosinophils, respectively (P> 0.05). As well as there were symptoms such as mortality, severe bleeding, chloride cell destruction, hypertrophy or epithelial cell edema, break downing Pilar, break downing epithelial cell, cell necrosis and aneurysm or telangiectasia. In a general conclusion, it can be said that the temperature of 14 °C is more suitable for rainbow trout, because the highest number of red blood cells, hemoglobin, hematocrit, and the lowest levels of cortisol and glucose were observed in the control group.

Prebiotics are non-digestible ingredients that by stimulating the growth and activity of bacteria in the intestines have beneficial effects for the host. However, few studies on the effect of prebiotics on reproduction and growth factors in ornamental fish were done. In this experiment, the fish was 20 weeks old. Tests carried out in the form of 4 treatments and 3 repetitions. Four diets, including treatment 1 (control), 2, 3 and 4 respectively containing 0, 0.5, 1 and 1.5 percent Imonoval was prepared. Fish were fed 3 times daily for 5 percent of body weight for 26 weeks. Results showed that the final weight and length were not significantly different in different groups. Relative fecundity, gonadosomatic index, length and weight of larvae were significantly lower in control group compared to group 3 and 4 (P<0.01). Results also showed that Imonoval has no effect on sex ratios. In this experiment, according to the results of the growth and reproductive factors, dietary 4 showed better performance than other treatments. In general, the use of prebiotic Imonoval in Mollies fish diet is recommended.

According to the importance of prebiotic inulin on sexual maturation in fish, this study changing the chemical composition (fat, protein, moisture and ash) in various stages of maturation muscle tissue in the zebra fish. Therefore, zebrafish larvae were fed with experimental diets containing (0, 1, 2 and 3 gr/kg diet) of inulin and two-stage sampling (45 days and 90 days after the active feeding) took place at every stage in the chemical composition (lipid, protein, moisture and ash) muscle tissue (based on the percentage dry weight) in fish muscle were measured. In the first sampling stage, fat and muscle protein was significantly higher than the second sampling stage (P<0.05). Given that the second stage fish were full sexual maturity, the amount of fat in muscle decreased (P<0.05). Moisture and ash levels were significantly (P<0.05) higher in the second stage sampling than the first stage. Overall, our results showed that different stage of living affected on muscle chemical composition muscle in Zebrafish.

In recent decades, coastal artificial structures have been increased in response to increment of storms, and coastal settlement. Round goby belong to family Gobiidae, one of the most important fish families in the Caspian Sea because of their abundance. In this study, we compared the feeding strategy and species diversity diet of the round goby, Neogobius melanostomus between artificial shores (Riprap structures) and natural shores including gravel and stony shores. According to the results, overall ten prey items consist of Xanthidae, Palaemonidae, Gammaridae, Amphibalanus improvisus, Ostracoda, Nereis diversicolor, Bivalvia, Foraminifera, fish remains and fish eggs were observed in the diet of round gobies. In artificial, gravel and stony shores, A.improvisus (%19.37), Ostracoda (%78.44) and N.diversicolor (%1.42) were most abundant food items. Analysis of the digestive tract contents revealed that round gobies consume wide spectrum of distinct food items in different shores. individuals of the fish have more specialized on distinct prey items at the artificial rocky shores in comparison with the other shores. At the artificial shores, round gobies are specialized on fish eggs, Ostracoda, Palaemonidae, Amphibalanus improvisus, Nereis diversicolor, Foraminifera and Xanthidae. 10, 8 and 6 prey items were observed in the diet of round gobies at the artificial rocky, gravel and sandy shores, respectively. Comparison of the species diversity in the gut contents of round goby showed higher value (1.94) at the artificial rocky shores than the gravel (1.62) and sandy (1.55) shores but, there was no significant difference in shannon index between artificial and natural shores.

The aims of the current study were feeding ecology, trophic interactions and trophic level estimation of three stingrays (Elasmobranchii; Dasyatidae) including Himantura imbricata, H. randalli and Pastinachus sephen in the Oman Sea. A total of 191 individuals belonging to three species were obtained and studied using VI, %FO, index of relative importance (%IRI), trophic level analysis and Pianka index. Results showed that H. imbricata had very specialized diet, consuming mainly on Crustacean. While H. randalli had moderate niche breadth and crustaceans, followed by polychaeta were the most important prey category in its stomach contents. Finally, P. sephen had the greatest niche breadth, with a varied diet divided among items such as Bivalve, Echinodermata and Polychaeta. An analysis of similarity showed significant differences among three species in their diet, indicating a partitioning of food resources between them. It also represented the minimum of food competition between the three species, facilitating coexistence within a habitat. The trophic levels of the stingrays are less than 4, a position shared them as intermediate food webs.

In These study, Phylogenetic and genetic diversity of Spirlin fish (Alburnoides eichwaldi) using cytochrome b sequencing in five rivers Zringl, Madarsoo, Safarood, Klisiyan, Zalki of the Northern Areas in Iran. Total of 26 specimens of spirlin collected and transported to the laboratory and DNA was extracted from the tissue. The results of the nucleotide sequences specimens showed Haplotype diversity is good, and 17 haplotypes was identify which Indicated the high genetic diversity These fish in rivers. Also based on Phylogeny analysis are three clades of spirlin in rivers. The present mitochondrial DNA data suggest that the southwestern populations in the Sefidrud drainage basin includes rivers and Zalki and Safarood (clade I) may be considered as A. eichwaldii, whereas the kelisiyan river populations (clade II) might be a distinct taxon of Alburnoides sp1. The clade of eastern populations (Gorganrud drainage basin, clade III) namely, Madarsoo and Gorganrud, are clearly separated from that of the kelisiyan (clade II) and Sefidrud (clade I) drainage basins, making a distinct species (Alburnoides sp2).

The main goal of the current study is to evaluate the impact of dietary herbal appetizer on the growth performance of growth out shrimp. This project was conducted at Caspian Sea research institute of ecology from 2014 to 2016. Totally 180shrimps with an average weight of 2 g were randomly distributed to 9 fiberglass tanks with area and depth of 1m2 and of 0.6 m. The experiment lasted for eight weeks and the shrimp were fed by three different diets as follows: 1. Commercial pellet contained no herbal additive (control diet) 2. Commercial pellet contained 1% herbal appetizer and 3. Commercial pellet contained 2% herbal appetizer. The results showed that prawn weight gains for diet 1, 2 and 3 were 6.28, 5.68 and 6.07 respectively. The estimated growth rate was 2.34g for control diet, 2.22g for 1% inclusion of the additive and 2.28g for 2% inclusion of the additive. Results also showed that inclusion of the additive did not change statistically average final weight (p>0.05). A larger weight gain was observed at 0% additive inclusion although this was not statistically different with other treatments. In conclusion, with regard to the observed results, herbal appetizer administration cannot improve growth, feed conversion rate and weight gain in common carps.

Aquaculture industry has substantially grown during the last decades. The remarkable growth of aquaculture in general and shrimp culture in particular has resulted in introduction of high load of organic and inorganic pollutants to the ecosystems adjacent to culture sites. In the present study, impacts of the shrimp culture in Shif shrimp culture site, in Bushehr province, on water quality and some biological characteristics of Amphibalanus amphitrite and Saccostrea cucullata were studied during culture season in 2016. Shrimp culture process caused significant changes in temperature, salinity, total ammonia nitrogen, total nitrogen, total phosphorus and chlorophyll a concentration. The high concentration of nutrients and thus food availability has, apparently, caused an increase in A. amphitrite density and the average length and weight of both A. amphitrite and S. cucullata that were exposed to the farm effluents. Management strategies such as bioremediation should be applied to reduce the adverse environmental effects of shrimp culture sites on their adjacent ecosystems.

The objectives of this study, was to evaluate the effect of dietary supplementation of Apple cider vinegar and propionic acid on histology of the hepatopancreas, total hemocyte count and intestinal microbiota of the Litopenaeus vannamei. In this study two hundred twenty-five Litopenaeus vannamei with an average initial weight of 10.2 ± 0.04 g, that they were fed diets supplemented with of Apple cider vingar and propionic acid after 60 days. Treatments included levels of 0, 1% Apple cider vinegar and 0.5% propionic acid diets. Shrimp were randomly sampled at the end of the experiment. The results indicated that, shrimp fed supplemental diets had significantly higher total hemocyte count (p < 0.05). no significant differences in blister cells were observed among treatments (p > 0.05), whereas the number of the resorptive cells significantly decreased in shrimp fed a diets containing Apple cider vinegar and propionic acid and a dramatic decrease was observed in Apple cider vinegar treatment (p < 0.05). The results indicated the tubule diameter in the hepatopancreas was significantly decreased in shrimp fed diet propionic acid. Total viable bacterial counts in the intestine of shrimp fed Apple cider vinegar and propionic acid diets were significantly lower compared to control group (p < 0.05). These findings indicate that the Apple cider vinegar was introducing suitable organic acid alternative and also it has the greatest potential for use as a diet supplement for L. vannamei.

Due to limitations in the exploitation of cline water resources, aquaculture cannot meet the growing demand of populations. Artemia is known as one of the important model organisms in researches and the most important live food in the aquaculture industry. In order to investigate the possibility or rearing and quality of cultured Artemia in present study, four different populations of A. urmiana, harvested from different areas of Urmia Lake, were reared in 75g/l salinity in two treatments of fresh water and chlorinated (3 ppm) waste water. The animals were fed with a combination of single-celled algae and single-celled yeast according to standard protocols. The growth and survival of the Artemia were measured on the third, seventh, eleventh, fifteenth and twentieth day of culture. At the end of the period, resistance to high temperatures of 35 and 38 centigrade and high salinities 360, 280, 240, 180, 120ppt were examined by adult Artemia. This study showed there are significant differences in the growth and resistance to environmental stresses (p<0.05) between different populations of A. urmiana obtained from different areas of the Lake. According to the results, rearing by the waste water was very effective in all growth factors, survival and resistance to environmental stresses compared to fresh water (p <0.05). The results of present study revealed that the chlorinated municipal wastewater is suitable for artificial rearing of Artemia which could produce a biomass with better growth rate and resistant to environmental conditions.

Aim of the present study was to identify the barnacles from the inter-tidal areas of Kharg Island by scanning electron microscope (SEM). Sampling was done from five stations in inter-tidal areas of Kharg Island in winter 2015 and spring 2016 (once in each season). The samples were freeze and transferred to laboratory. After morphometric study, the samples were prepared for study by SEM. Three species were identified in this research and their most existence were in high and mid areas of inter-tidal zone. All founded species belonged to superorder Thoracica, order Sessilia, suborder Balanomorpha and families of Tetraclitidae, Balanidae and Chthamalidae. The shell of Amphibalanus amphitrite has six calcareous separate plates with smooth outer surface. The shell of Chthamalus barnesi has six calcareous plates and growth lines were observed. The shell of Tetraclita rufotincta has four calcareous plates without any obvious suture and also radial decorations and growth lines were observed. Evaluation of barnacles by Scanning Electron Microscope could be an appropriate method for more exact identification of barnacles.

The present study aimed at evaluating the biodiversity of planktonic rotifers in a horizontal salinity gradient in both summer and winter 2014 at the Bahmanshir river estuary. Planktonic rotifers were sampled using 100 μm mesh size plankton net from six stations with three replications. In this study, 14 species of rotifers belong to 6 genera and 3 families were identified. The species Brachionus rotundiformis and B. plicatilis were dominant at all stations. Environmental factors such as temperature, salinity and dissolved oxygen were also measured. The results of Spearman correlation test showed that the highest negative relationship between electrical conductivity and salinity with -0.94 and -0.93 correlation coefficient respectively with abundance of rotifers (P<0/05). So along the salinity gradient toward the stuary mouth species structure was changed and speceies richness decreased. Results indicate that differences in salinity between stations of the river account for differences in the species composition and diversity. The highest abundance of rotifers was found in summer and in station 1 (1362.1 per cubic meter) and In the winter there were no rotifers observed in station 6. Maximum amounts of Shannon- Weaner index of diversity in summer and dominance index of Simpson were estimated in summer and winter with amount of 1.52 and 0.4 respectively. The results of this study showed that salinity is the most influential factor on the diversity and density of rotifers in the Bahmanshir river.

In this study, the catch efficiency of Talang queenfish (Scomberoides commersonnianus) was examined for the surface, mid-water and bottom drift gillnets using cumulative probability distributions of retention in coastal waters of Bandar Abbas and in the western part of Hormozgan province during the years 2014-2015. For this, the transverse morphometric data for girths in three positions of the fish body such as Opercular girth (OP), girth at the beginning of first dorsal fin (D1) and girth at the beginning of second dorsal fin (D2) along with fork length have been collected for four gillnets in different stretched mesh sizes of 101, 114, 165 and 171 mm. Results from the analysis of covariance (ANCOVA) showed that girth at D1 is considered to be the maximum girth of the species (P<0.05). Fish were tangled in the nets depending on meh size. Unlike the 165 and 171 mm nets, in mesh sizes of 101 and 114 mm the selectivity curves were not fitted to the length frequency distribution. Base on the selectivity curve, the optimal length of S. commersonnianus for the nets of 101, 114, 165 and 171 mm was obtained as 44, 52, 66 and 76 cm respectively. It seems that nets with meshes of 165 and 171 mm are suitable to harvest S. commersonnianus stocks aimed at capturing mature fish in order to approach to sustainable exploitation level, whereas it is needed to do further study on filed for any suggestion on the nets of 101 and 114 mm.

In order to come up with the sustainable fishing pattern of longtail tuna, there was a need to the gillnet mesh size designed to allows immature fishes escape and provide an opportunity for them to spawn at least once. In this review original gillnet mesh size (140 mm stretched), 114 and 132 mm mesh size nets were examined. The percentage of immature species in 140, 132 and 140 mm nets were 97%, 84% and 78% respectively. The linear relationships between fork length and head (in pre gill), gill, body (in first dorsal fin) and second dorsal fin perimeters were (HP=0.48FL+0.83), (GP=0.51FL+2.35), (BP=0.60FL+0.87) and (SDP=0.49FL+3.89) respectively. There was significant coefficient between linear equations and perimeter in first dorsal fin was maximum body perimeter. The elastic ratio were 24% in first dorsal fin and 19% in head and gill. The optimum standard gillnet mesh size based on relationship between fork length - body and length at first maturity was 170 mm stretched.
