Asiatic Cheetah, which is critically endangered subspecies has survived only in arid habitats of the central plateau of Iran to less than 40 populations. The species population in the center of Iran, which mainly includes Yazd Province, has had the highest population decline and has lost the population dynamics. Hence, 2.9 million hectares of Yazd province’s habitats in which the species has been extinct locally were investigated for climate change over a 14-year period, from 2001 to 2014. In this study, firstly, we used the Maximum Entropy method to model the Asiatic Cheetah suitable habitat. Then, by using the Modis time series method, we identified the maximum land surface temperature and the weather stations data were used to finding the total annual precipitation changes. Assessment of the maximum temperature changes in the cheetah habitats showed that the average temperature increased by 24 percent of the study area during this period. Also, some parts of the southern part of the study area had an obvious reduction of the total annual precipitation. However, the study results showed that climate change factors, including changes in the maximum land surface temperature and total annual precipitation variations, during the study period, were not significant. Therefore, the most important reasons for the reduction of Asiatic cheetah population dynamics in the study area, during the study period are non-climatic factors.

Caracaland mongoose are both species from suborder of Feliformia that live in different regions of Iran. The shape and size of bones of the fore limb have an important role to the state of the body conformation and balance of carnivores and they are also important because of their predilection for bait. The aim of this study was to investigate the morphology of scapula, humerus, radius and ulna in these two species. Investigating and recording of these findings can be helpful as the means of differentiating species, helping wildlife practitioners in various fields of veterinary science and preserving the population of these species. In order to carry out this study, the carcasses of an adult caracal and a mongoose were transferred to anatomical laboratory at Semnan University. After completing the preparation stages, morphological studies and of the bones were performed and also the required images were obtained. In general, it can be concluded that the biggest anatomical differences are in the scapula. This bone in the mongoose is similar to the dog and in the caracal is more like to cat. In the humerus, the most important difference among carnivores is in the distal extremity. Also the most morphological similarities among carnivores, were observed in the radius and ulna.

Today, as population growth has caused extensive destruction of wildlife habitats, conservation and extension of habitats has an important role in preserving wildlife and, consequently, biodiversity. And by assessing the habitat, the quality of the habitat can be achieved easily. The protected area of Sangemes is one of the best and safest habitats of Jebir in Kerman province. The aim of this study was to determine the effective factors on Gazella bennettii 's visibility using the HEP method during the years 2016 to 2017 for spring (The promise of forgiveness), summer (heat and dehydration) and autumn (mating period). The main variables used to evaluate the habitat of the Gazella bennettii species are slope, elevation, aberration, geochemistry, distance to the water source, middle valleys. At first, the habitat was divided into three stations (mountains, hill and plains), then the variables of the index were determined using the HEP method. The results of the region's assessment were shown using the HEP method; Hill habitat in spring-summer season with HSI index, 0.89 is more desirable than other parts. Among the variables used, the biomass variability in all seasons was higher for both stations, which indicates the region's richness for species nutrition. From the results of this study, conservation and management measures can be used to increase the level of desirable habitats in Kerman province.

This study was conducted to investigate the growth performance, body dimensions and fat-tail measurements of Chall male lambs reproduced from outbreeding of rams and ewe in Qazvin region. Two hundred 18 month ewe lamb were selected from a 1000-head flock and divided in two groups randomly. The first group (control) mated with rams from self-flock and the second group (treatment) mated with rams from other flock. After lambig, 10 male lambs from each group were selected randomly for recording the body dimensions and fat-tail measurements. The results showed that the average circumference of neck (36.6 V 35.1 cm), fat-tail circumference of upper part (40.4 V 37.1 cm) and fat-tail length of middle part (15.1 V 14 cm) in the treatment group was significantly higher than the control group. The effect of ram in control and treatment on birth weight (4.9 V 4.8 kg), weight at two, four, six and eight months (45.1 V 43.2 kg), final weight gain (40.2 V 38.4 kg) and body height and length, circumference of heart girth, loin width, diagonal length, and fat-tail measurements including length at the right, left and gap part, width at top, middle and down part, circumference at top, middle and down part, depth at top, middle and down part and fat-tail weight (2.4 V 2.3 kg) did not change significantly. In total, using rams from other flocks, increased circumference of neck and some fat-tail trait, but had no effect on growth performance of lambs.

This research was carried out to compare the nutritional value of two seaweeds in coasts of Bushehr province (Sargassum ungustifolium) and Sistan and Baluchestan province for ruminants feeding. To determine the digestibility, each seaweed was mixed in 10, 15 and 20 percent ratios with dry alfalfa, and each feed was tested by fecal sampling method on four adult male sheep. Six treatments consisted of three feeds containing Sargassum and three feed containing Cystoseira in a randomized complete block design. The chemical composition of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and gross energy (GE) for Sargassum were 92.6, 58.6, 8.4, 16.9, 16.6 percent and 2316 cal/g, respectively and for Cystoseira were 93.2, 82.2, 15.2, 38.17, 27.7 percent and 3267 cal/g, respectively. The results showed that nutrients percentage of mentioned above, was increased significantly, except for DM of Cystoseira in comparison with Sargassum. Among the treatments of Sargassum and Cystoseira feeds, the best nutrients digestibility coefficient was in 20 percent treatment of Cystoseira feed that for DM, OM, CP, NDF, ADF and GE were 58.8, 60.8, 64.5, 49.7, 50.8 and 62.1 percent, respectively. Totally, the results showed that due to higher CP and GE and lower Ash (higher OM) in Cystoseira rather than Sargassum, it is more suitable for ruminant feeding and the most suitable level of Cystoseira is 20 percent.

This Experiment was carried out to determine the effects of urea and molasses -treated Corn Single Crosses SC 704 Stalklage in fattening performance of Turky-Ghashghaii male lamb. At first, corn residues were gatherd after harvesting of corn grain by Cambine method and processed with urea and molasses. Then, evaluates its chemical composition and in vivo apparent digestibility. The Corn Stalklage treated and untreated were included in the ration as to replace zero , 30 and 50% of total forage in a completely randomized design in the ration of fattening lambs. The rations (iso-nitrogenous and iso-energetic) were fed to 6 Turky-Ghashghaii ram lambs. Results showed that In vivo digestibility coefficients for DM OM, NDF and ADF had significant differences between treated and non-treated Corn Stalklage. It seems that according to the results of fattening traits and digestibility, the use of treated corn residues with 4% urea plus 10% molasses with ratios of 50% as total forages in feeding lambs in comparison with other treatments, had a better daily weight gain.

Manipulation of ruminal fermentation can be considered as an optimization procedure for methane emissions. Although, magnesium oxide meet a large portion of the magnesium needed for ruminants, it has a proper buffering capacity and can alter the rumen fermentation pattern. In this study, the effect of a commercial magnesium oxide in the levels of 1, 2, 3 and 4% of a high-concentrate diet was investigated in an in vitro batch culture prepared from sheep's ruminal fluid. Some of fermentation and degradability parameters, methane emissions and gas production parameters were measured when the diet incubated to the culture medium. The pH of the culture medium was significantly increased compared to the control, but the total volatile fatty acids (TVFA) did not change when magnesium oxide was added to the culture medium. The lowest amount of ammonia nitrogen (23.26 mg/dL) was observed at 4% of magnesium oxide. The gas production parameters and methane emissions were significantly lower in the treatments containing magnesium oxide when compared to the control group. Although the partitioning factor (PF) and the microbial mass yield were not affected by the treatments, but the efficiency of microbial mass synthesis increased significantly in the treatments containing magnesium oxide. It seems that the use of magnesium oxide can improve the rumen fermentation pattern via enhance the efficiency of microbial mass synthesis; reduce methane yield and increase of organic matter degradability. Also, further studies are needed to determine the effects of magnesium sources according to in vivo conditions in the future.

This experiment was conducted to determine the chemical composition and evaluation of protein quality raw tomato pomace (RTP) and fermented tomato pomace (FTP) in broiler chickens. The amount of dry matter, fiber and crude protein in RTP were changed from 92.96, 35.13 and 14.35 to 91.40, 30.16 and 15.54% in FTP, respectively. Lactic acid bacteria population (log10 CFU/g) in RTP was changed from 7.53 to 14.85 in FTP. The experiment was conducted in a completely randomized design with four treatments including nitrogen-free diet, soybean meal, RTP and FTP as semi-pure diets on broiler chickens. Protein efficiency ratio (PER), net protein ratio (NPR), feed efficiency and weight gains chickens were investigated. The results showed that the PER at 14 and 17 and the whole period for FTP was 2.69, 2.72 and 2.70, for RTP 2.36, 2.03 and 2.24, and for soybean meal 3.06, 3.26 and 3.13, respectively. NPR for FTP was 3.84, 3.76 and 3.82, for RTP was 3.47, 2.92 and 3.28, and for soybean meal 4.03, 3.99 and 4.02, respectively. Although weight gain and feed efficiency in chicks fed with FTP was lower than soybean meal, but these values were higher than the RTP (P <0.05). Therefore, due to the improvement in the quality protein FTP, it can be used to feed broiler chickens.

Habitat suitability prediction for the animals is one of the ways to achieve the conservation goals for biodiversity. In the present study, habitat suitability of Lacerta media has been evaluated. Based on the maximum entropy result, northwest and western Iran has been predicted as the most suitable for the species presence. Also there are several records of the species presence in Alborz, Markazi, East Azarbaijan and Esfahan provinces that currently situated outside of the suitable predicted region. Precipitation of the coldest quarter with contribution more than 40% was distinguished as the most contributed environmental variable for species presence. Unsuitability prediction of the species presence in central plateau and East Azarbaijan province directly has been influenced by the recent decreasing of winter precipitation. Also, disturbance the habitats of the species along valleys and rivers is the main factors to the decreasing population size of the species. Finally, evaluation the effective factors for species distribution and finding new suitable areas for species presence can help to prevent the species extinction risk in the wild.

Lizards have significant roles in lifecycle and are related to humans either directly or indirectly. Identifying the fauna of a region is the most necessary and significant biological and fundamental research on it. Golestan province has a variety of climates due to its special geographical location. In this study, 26 specimens of keeled rock gecko, Cyrtopodion scabrum were collected from different areas of Golestan province since 2017 by hand. Colorful photos were taken; then fixed in alcohol 75% and finally identified using valid keys. 14 morphometric and 13 meristic characters were studied in all specimens. Sexes of the adult specimens were determined by observing the pre-anal pores (PAN) in males and their absence in females, and finally, with a brief dissection of the specimens and observation of genital glands. Analysis of data descripted using SPSS (version 22), T-test, Kruskal Wallis Test and PCA were analyzed Slight differences between mean of characters of males and females were observed based on descriptive analysis. It was not observed significant difference in morphometric characters between two sexes based on the analysis of T-test. Meristic characters (pre-anal pores) had significant difference, indicating sexual dimorphism in this species. Also, PCA analysis revealed that there is no separation between males and females based on morphometric and meristic characters.

The Caspian Sea is the world's largest closed lake that is very important. Bony fish is the most important and most valuable fish in the sea, which unfortunately its reserves in recent years for various reasons is declining. The present study was carried out to investigate the effect of the stress of cavity on changes in physiological parameters effective in the reproduction of Caspian white fish. Reproduction of fish was adapted to the new conditions for 3 days in order to adapt to the new conditions and then distributed equally to three fiberglass tanks and held for 10 days in captivity. After 10 days of storage, to the fish of first and second treatment of the sexual stimulation hormones (Ovaprim) were injected. Blood samples were taken from the samples during 3 stages. The results showed that plasma beta-estradiol 17 hormone levels were decreased after 10 days and after sexual examination in all experimental groups compared to the beginning of the experiment which, this decrease after sexual maturity was significantly higher than before the start of the experiment. Plasma testosterone levels decreased significantly in all experimental groups (P<0.05). Changes in progesterone levels in all experimental groups were not significant (P>0.05). Based on the results of this study, it can be stated that the stress of the cavity in the reproduction of white fish has affected the physiological parameters studied. The relative reduction in the parameters of the examined blood plasma of these fishes shows these effects.

The Alburus chalcoides (Guendenstaedt, 1772), of Cyprinidae family, is a valuable bony fish of the Caspian Sea. Checking the start of a feedind is one of the most significant cases of larval growth. Actually, Specifying the day of opening the mouth of the fish and the day the active nutrition and pelleting is started will also affect the growth of the fish, especially as the guinea pig fish feed more on protein sources and this will speed up the digestion and absorption of food. The King of Gypsy was opened from the fifth day after hatching his mouth and was seen as a gutter. To evaluate morphological characteristics of larvae and infants, 10 samples were considered.The length of larvae on this day is 4.6 ± 2.2 mm and weighs 0.010 g. On this day, larvae can use environmental food in the water, but given the size of the mouth of this fish on the eighth day to the size The size is 84 micrometers (5.5 ± 4.4 mm in length and 0.013 grams in weight). This day was calculated as a starting point for feeding pellets, which could be used for larvae in addition to perennial food from pellet. The purpose of this research is to determine the appropriate feeding time for fish.

The present study investigates effects of different levels dietary sodium acetate (SA) salt on the growth and activity of digestive enzymes activity in goldfish (Carassius auratus). 120 fish (mean initial weight 14.24 ± 1.29 g) were fed 3 times a day with four experimental diets supplemented with 0, 2.5, 5 and 10 g/kg SA for 10 weeks. Biometry was done to measure growth and nutritional indices every two weeks. Also, six fish were randomly sampled at the end of experiment to study the activity of protease and lipase enzymes. The obtained results showed that fish fed with 5 g/kg SA had highest final weight, so there was a significant difference between the treatments compared to other treatments (P<0.05). However, no statistically significant difference was observed in other growth indices between control and SA fed fish (P>0.05). There was no significant difference in the lipase and protease activities between different treatments (P> 0.05). The results of the current test showed that the use of 5 g/kg SA could increase the growth of this fish. However, no notable effect was noticed in case of the activity of the digestive enzymes.

The present study was designed and performed to evaluate the effects of various concentrations of folic acid and riboflavin on some growth, blood and immune indices of Rainbow trout (Oncorhynchus mykiss) fingerlings. For this purpose, 891 fingerling rainbow trout with the average weight of 6-7 g were distributed in 27 fiberglass tanks with 9 treatments randomly (33 fish in each tank). Rainbow trout fingerlings was fed with normal diet and diet containing various levels of folic acid (0, 6 and 10 mg) and riboflavin (0, 20 and 30 mg). At the end of the 60-day period of breeding, 30 fish from each treatment were selected randomly and blood sampling was performed after measuring the growth factors. The results showed that the highest mean body weight gain, specific growth factor, daily growth factor, white blood cells, red blood cells, hemoglobin and hematocrit were observed in fish fed diets containing 20 mg riboflavin and 10 mg folic acid and showed a significant difference with control group and other treatments (P<0.05). In terms of survival rate, there was no significant difference between treatments. Based on the results, the best formula for feeding rainbow trout fingerlings is a combination of 20 mg riboflavin and 10 mg folic acid per kilogram of dry food. Due to the low consumption of vitamins, the use of this formula is economical in cold water fish breeding farms and has economic justification.

Phytoplankton and algae are as the first level of the food chain and food producers for other organisms in the aquatic environment. These organisms acquire their nutrients in the process of photosynthesis (N and P) from the aquatic environment. In this study, the amount of purified fish wastewaters was studied by microalgae (Chlorella vulgaris) in a period of 18 days. The present study was conducted in a laboratory system and on the wastewater outlet of fish farms. For this purpose, a 5-liter semi-industrial reactor was designed with a mixer blade, a porous plate, and a compressor. The required algae stock on the basis of density was cultured in the laboratory environment and then was injected into the bioreactor compartment containing fish wastewater. The averages of nitrate, nitrite, phosphate, and ammonium, TDS, TSS and BOD were 1.94, 2.22, 0.39, 4.11, 2.2, 1.94, 2.39 mg L-1, respectively. Also, PH and electrical conductivity were 7.52 and 1315 µ mho cm-1. The results showed that algae films efficiently reduced the amount of contaminants in the reactor space. This decreasing trend has increased over the course of the encounter. At the end of the exposure period, all parameters except phosphate have been reduced by almost half. The algal reactor can effectively reduce the organic loading of fish farms, which will partially prevent environmental contamination.

To determine the nutritional value of giant gourami as a new edible species and compare it with common carp as a common species, fishes were purchased in the same weight range (5±0.27 and 5.02±0.26 g, respectively) and presented to concrete ponds in a monoculture system, two treatments with 3 replicates. Fish were fed with common carp commercial diet of for one year. At the end of experiment, protein and carcass moisture content were significantly higher in common carp, as well as ash and total lipid in giant gourami. Total omega-6 fatty acids were registered higher in common carp than giant gourami fish, significantly. There were no significant difference in total omega-3 fatty acids, levels of high unsaturated fatty acids and EPA and DHA content at two species. ω-3/ω-6 ratio was significantly higher in giant gourami than common carp. In contrast, the ratio of polyunsaturated fatty acids to the saturated fatty acids of common carp was more favorable than giant gourami, and the difference was statistically significant. In conclusion, according to the EPA and DHA content in the two tested species, and also the promotion of the ratio ω-3/ω-6 in giant gourami, due to the qualitative features and nutritional value of giant gourami, it can be considered as a valuable farmed fish.

The results of fertilization rate and hatching rate were compared with the general method of the workshop (egg washing with carbamide solution). 9 concentrations of sodium chloride were used at 25, 50, 100, 250, 500, 1000, 2000, 4000 and 10000 mg / L for three times 15, 30 and 60 minutes. Three concentrations of tannic acid (500, 1000 and 1500 mg / L) were used at three times 0.5, 2 and 5 minutes. All three concentrations were performed in three replicates. After activation, 50 milliliters of the enzyme were added at a concentration of 2 milli liters per liter for 20 minutes and exposed at 45, 60, 75, and 90 seconds. Finally, they were washed 4 times with hatchery juice and transferred to incubation. The results showed that the best fertilization rate (99.57%) and hatching rate (99.46%) were related to treatment 1 at a concentration of 500 mg / L in 0.5 time It was a minute. Regarding removal of egg adhesion by sodium chloride treatment, the best fertilization rate (87.1) and hatching rate (28.86) were related to 1000 mg / l treatment at 30 minutes. The highest percentage of fertilization (97.52%) and hatching (96.72%) with alkaline enzyme was 50 mg / L treatment at 45 seconds.

The use of natural and vegetable ingredients as an additive in fish diets will increase the health of the host. The aim of this study was to evaluate the effects of adding sugar beet molasses to carp fish meal to evaluate some blood indices. The experiment consisted of 360 pieces of common carp with an average weight of 22 ± 2.5. After one week of adaptation, it was fed for a period of 8 weeks. The experiment was carried out in the form of 4 treatments and each treatment with 3 replications including: Molasses (treatment 1), diet containing 0.5% molasses (treatment 2), diet containing 1% molasses (treatment 3) and diet containing 2% molasses (treatment 4) Done. The fish were fed daily with 3% body weight and twice daily with experimental diets. Food from the control group, the commercial food of the common carp of the corporation was no molasses. The results showed that red blood cells were significantly increased in 2% molasses. Hemoglobin was also found in 2% molasses (P <0.05). MCHC also increased in 2% molasses. There was no significant difference between the treatments after the differential count of white blood cells. In general, a diet containing molasses was effective on the blood indices of common carp, increasing the number of red blood cells and increasing hemoglobin in 2% molasses.

This research was carried out for comparing the efficiency of nanosil (Hydrogen peroxide with silver ions) and malachite green in order to control the fungal contamination in eggs of sturgeon (Acipenser persicus and Acipenser stellatus). Nanosil treatment at concentrations 40, 80, 100 mg/l, malachite green treatment at concentration 2 ppm and control treatment (all of them with three replicates) were evaluated in Yushchenko incubators during three days so as to compare and control the fungal contamination and determine the best concentration in different treatments in reproductive and restoration center of Sturgeon fishes in Sangar from April to June 2014. Firstly, adult breeders were selected and after fertilization, total number of seeds, fertilization percentage, percentage of fungal, healthy and unhealthy eggs, unfertilized eggs, total number of larvae and hatch percentage were calculated. The results showed that the lowest percentage of unfertilised eggs, the highest percentage of healthy eggs, the lowest percentage of fungal eggs and the highest percentage of hatching in Acipenser persicus was related to nanosil 80 mg/l (P<0.05). Also, the results of comparison of different treatments showed that the lowest percentage of unfertilized eggs, the lowest percentage of fungal eggs and the highest percentage of hatching in Acipenser stellatus was related to nanosil 80 mg/l (P<0.05). In a general, it can be said that nanosil 80 mg/l had a more effective effect in hatching percentage and disinfection of eggs. Because malachite green has a vast number of disadvantages, it is recommended using nanosil as a new disinfectant.

In order to know the optimal level of addition of vitamin B12 to water, in a Aquaponic system using Nile tilapia (Oreochromis niloticus) and Saffron plant (Crocus stativus), 240# Nile tilapia fish and 120# corms of saffron were randomly divided into 12 experimental groups and influenced by treatments of adding 0 (control), 10, 20 and 30 mg L-1 vitamin B12 to water, weekly, for 60 days experimental period. At the end of the experiment period, weight gain and other indices of fish growth performance did not show any significant differences in any of the treatments, but some growth performance indices of saffron plants such as leaf length showed the lowest rate in treatment of 30 mg L-1 and root weight in treatment of 30 mg L-1 vitamin B1 in water was significantly higher than other treatments. Measurement of serum biochemical parameters of fish showed that with increasing levels of vitamin B12 in water, treatment with 30 mg L-1 vitamin in water showed the highest amount of Alkaline phosphatase enzyme and Aspartate aminotransferase enzyme in blood serum of fish. Finally, the results indicate that adding 10 to 20 mg L-1 vitamin B12 to the water of the aquaponic system using saffron plant and Nile tilapia can improve the growth and yield of the saffron plant.

According to the entering of municipal and agricultural wastewater into the Gorganroud River, the purpose of this study was a determination of the composition, abundance, and diversity of the benthic communities in this river as a part of the nutritional levels of this aquatic ecosystem. This study was conducted in 5 different stations on a monthly basis during a one-year sampling period between 2009-2010. Sampling operation was carried out using a Surber sampler (With an area of 1600 centimeters) with 3 replications. Based on the results, 3 phyla and 16 genera of benthos fauna were identified that annelids, arthropods, and mollusks had 3, 4 and 9 genera, respectively. The highest biodiversity of 2.67 and 0.86 was in obtained autumn and the lowest biodiversity with a seasonal mean of 2.16 and 0.81 was obtained in summer. Based on the comparison of benthic communities, the average density of the final benthos assemblages of four seasons in the determined stations was significantly different (P<0.05), but the average density of the seasons was not significantly different (P>0.05). According to these results, there was no significant difference between temperature, dissolved oxygen, and acidity level of different stations (P>0.05), and depth showed the significant difference between different stations (P<0.05). Also, correlation analysis of water factors and density of benthos communities showed a lack of correlation between them at different stations (P> 0.05).

In the study, dominant meroplankton were Bivalvia larvae, Balanus improvisus and Nereis diversicolor. The abundance of Bivalvia larvae increased sharply in 1996, average abundance of Bivalvia larvae was measured about 26000 ind.m-3. There were increased and declined in Balanus improvisus abundance after Mnemiopsis leidyi bloom between 2001 and 2013.The abundance of B. improvises varied from 98 to 4700 ind.m-3 in 2001 and 2010, respectively. In addition, the bloom of B. improvises was recorded amount 3100 ind.m-3 in spring. The abundance of N. diversicolor varied between 60 and 1500 ind.m-3 in 2001 and 2006, respectively. The N. diversicolor did not show before M. leidyi bloom (1996). The seasonal bloom of N. diversicolor was observed amount 500 ind.m-3 in summer. The vectoral distribution of meroplankton was observed at 50 m depth in surface layers. The finding displayed, meroplankton abundance decreased from inshore to off shore. The environmental parameters and exotic species could be important reason in temporal and spatial of meroplankton in the southern Caspian Sea.

This study carried out in order to investigate the impact of Bandar Anzali's breakwater on the diversity and abundance of Macro-invertebrates. Twelve stations were located in two sides of the breakwater in the wall and in the sea substrate. The sampling carried out from November 2017 until August 2018, seasonally. In the substrate stations on the sea side, the bivalve species Cerastoderma glaucum and Amphipod Stenogammarus compersus were observed in all stations with an average 344.1 ± 11.6 and 7.77±55.9 n.m-2, respectively. The worm species Streblospio gynobranchiata with abundance of 33.3 ± 42.5 n.m-2 was found only in the estuary section. Among the Macro- invertebrates on the breakwater wall; the Mytilaster lineatus and Mytilopsis leucophoeata were found on the sea side and in the estuary side, respectively. Their abundance had not significantly difference in different seasons. The Amphipoda Melita mirzajanii and Hediste diversicolor were also frequent in the wall of breakwater with 4106±1878 and 495±110 n.m-2, respectively. The crustacean and worms had more abundant in summer 2018 than other seasons. According to ecological indices, species diversity was more in the sea side rather than the estuary side for both habitats; the sea substrate and the wall. Furthermore, the species diversity was more in the wall of breakwater rather than sea substrate. The artificial constructs such as breakwater have an important role to increase of the species diversity.

Zooplanktons have a special role in the food chain and the ecological pyramid of the marine ecosystem. The aim of this study was to investigate the effect of Monsoon on biodiversity of zooplanktons in the eastern coasts of Chabahar. Sampling was carried out on the eastern coast of Chabahar using a 100-micron zooplankton net with a horizontal extension stretch of 30 cm at 8 stations in the Chabahar bay during four seasons from summer of 2016 to spring of 2017. According to the results, Copepoda have rise to 66.87 percent of the zooplankton population. After the Copepoda, bivalvia (7.53%) and Thaliacea (6%) have highest presence and Polychaeta, Cephalochordata, Ostracoda were found to be the lowest (in total with 2.22%) in different sampling seasons. The highest and lowest Shannon index was calculated, respectively, in autumn (3) and spring (0.99), respectively, in the autumn and winter (0.95), and in summer and spring (0.94), respectively. The highest and lowest indexes of uniformity were in autumn and spring (0.97) and summer (0.94) respectively. According to the results of this research, the structure of the zooplankton communities in this region is affected by the changes caused by the monsoon winds and the coastal upwelling flows. The cycle of production and seasonal changes of zooplanktons depends on the environment response to these changes. Ultimately, when zooplankton organisms are exposed to severe disturbance (monsoon), several species become dominant and decrease the species uniformity.

Investigating the ecological and biological conditions of the rivers can indicate potential pressures on them. Different orders of benthic macroinvertebrates have different tolerance for contamination, which are used as indicators of water quality in many cases. This study has examined the structure and assemblage of benthic macroinvertebrates in Karaj river. Considering the factors that cause environmental disturbance, the classification and assessment of water quality of Karaj River at the stations were done. From winter until the end of autumn (2017), 4 sites through Karaj River were sampled for macrobenthos. Based on the results, totally the samples were identified, belonging to 5 class, 10 orders and 23 families. The most abundant groups in Karaj river were Ephemeroptera ,Plecoptera and Diptera. In general, the results show that the river water has a moderate pollution based on the Shannon index and has a suitable quality according to the Hilsenhof index in the upper stations (Sierra and Polekhab) and has less quality at the lower stations of the Dam (Aderan and Pourkan). Also, based on Simpson index, dominance is high at Sierra and Polehwab stations, and based on Hill index Aderan and Puorkan have more uniform populations. Finally, the results show that biological index can present the quality of water.

The study of effect four diets formulated containing vegetable oils including canola and corn oils and their mixture, in three replications each, was carried out to feed N. diversicolor during two months. At the end of the experiments, growth performance in each treatment included total biomass, L3 length, specific growth rate (SGR), body weight increase (BWI), and survival rate were measured. Biochemical composition including total protein, total fat and fatty acid profile of diets and worms body carcass were analyzed. The results showed that there was no significant difference in the growth performance of worm from diets containing different oils with control treatment (worms fed from diet of without oil). The results indicate that the fat in the diet has no effect on the growth of the worms, but the presence of these vegetable oils in carcass composition was important. The results of this study showed that all saturated and unsaturated fatty acids in the diet, except of the control treatment in the N. diversicolor, were higher than their dietary. In the present study, N. diversicolor, fed from diet containing of canola oil, had the highest ⍵-3 fatty acids. The highest EPA level and ratio of ⍵-3/⍵-6 in the worms fed canola oil were higher than formulated diet containing canola oil. Totally, treatment 1, including diets containing canola oil, was more suitable for increasing the growth perfoermance and unsaturated fatty acids of worm than other treatments.

Sturgeons are considered to be the most valuable fish in the world and the Caspian Sea. the Collapse of the former Soviet Union and the uncertain division of the Caspian Sea unfortunately have led to environmental problems, as well as an increase in illegal fishing, has led to a significant reduction in the valuable species of the Caspian Sea. In spite of various management inconsistencies, advising and managing the Islamic Republic of Iran after the glorious victory of the Islamic Revolution led to the adoption of uniform policies of the Caspian Sea administration, which can be used to control sturgeon fishing and increase the rebuilding of their reserves. After the glorious victory of the Islamic Revolution, significant activities have been undertaken in this area, including: the restoration of reserves and the release of infants to the sea, the cultivation of sturgeon in unconventional domestic waters and cages, increasing research centers and universities with the management of sturgeon stocks management and Introducing the precious Persian dish. Altogether, in spite of various management inconsistencies, the advisory and management of the Islamic Republic of Iran led to the adoption of uniform policies of the Caspian Sea administration, which could be used to control sturgeon fishing and increase the rebuilding of reserves. Between countries of the Caspian Sea, only Iran has been trying to solve this crisis, which is a significant reduction of sturgeon fish. Many activities, including the construction of reproduction and restore of sturgeons from Iran, have been carried out in this area, which could lead to worthy result.

The most efficient approach to control virus agents is the use of the resistant plant varieties. The RNA silencing-based resistance is the best way to establish the resistant plants against viruses. Grapevine fanleaf virus (GFLV) is one of the most destructive viral diseases of grapevines worldwide. In order to investigate the possibility of the resistance induction against GFLV using RNA-mediated induction of resistance, nucleotide sequence of two genes of GFLV was used to produce a hairpin construct. The construct was developed using intron and also the fragments in sense and antisense directions in front of 35S promoter in pGA482G. Agrobacterium tumefaciens was used to transform Nicotiana benthamiana plants. To evaluate resistance to GFLV after confirmation of transformation, the transgenic plants were mechanically inoculated with this virus. 10 days after virus inoculation, the inoculated plants showed various reactions including resistance, susceptibility and delay in symptom production. ELISA assay confirmed the absence of the virus in the resistant transgenic plants. No symptom was observed in these plants even a month after inoculation. The transgenic plants in which the virus was detected by ELISA reaction, mosaic symptom similar to that in wild type plants was appeared one week after inoculation. The results of this study showed that the developed construct containing a sequence of GFLV is efficient to establish the resistance to this virus and could be applied to produce the resistance in the different grape varieties.
