This study was conducted to investigate the interspecies morphological variation of Sabzug (Cyprinion watsoni) in response to environmental factors using geometric morphometrics method in Southern and Southeastern Iran. Hence, nine populations including 270 specimens of Sabzug were collected from four Southern and Southeastern basins of Iran during summer 2012 using electrofishing. The specimens were anesthetized in clove solution 1gl-1, fixed into 4% formalin and then transported to the laboratory for further examinations. The left view of specimens was photographed and fifteen landmark-points were defined and digitized on 2D images using tpsDig2 software. The shape data were analyzed based on Principal Component Analysis (PCA), Canonical Variate Analysis (CVA) and Cluster Analysis (CA). The results revealed a significant difference between populations in terms of body shape (P<0.01). Also, the Bastak population was considerably separated from all other populations. The results can be summarized as: the Sarze, Ilood, Jegin and Sarbaz populations had more body height, in Ilood, Kash, Mashkil, HalilRood and Jegin the head was longer and in Ilood, HalilRood and Jegin the head height were more than other populations. The Bastak population was differentiated due to possessing the least body height, longer head, more up-warded mouth and less caudal peduncle length than others. These results revealed some morphological responses of Sabzug to environmental selective pressures, which can be used in taxonomic and systematic study of the genus Cyprinion.

Nowadays, with the growth of the world population and the need for people to achieve healthy variety of protein sources, aquaculture plays an important role in providing the required protein. In this research, 135 beluga with an average weight of 1.15±20.82 kg obtained from culturing and reproduction sturgeon center of Shahid Rajai and maintained from July to September 2012. The fishes were distributed in Echinacea (E), Garlic (G), and control(C) group with three replicates. The fish were fed a diet containing garlic and Echinacea for 60 days. The results of this study indicated that the fish in treatments E and G had the highest final length and weight with significant differences in comparison with the control group (P≤0.05). Also, food conversation rate, special growth rate, body weight increase, average daily growth, condition factor and velocity of weight showed a significant difference between Echinacea and Garlic, compared to control group (p≤0.05).The findings of the present study indicates that adding Echinacea and Garlic in beluga diet can induce positive impact on growth performance and feed efficiency in beluga and can be a good complement for begula’s diet.

Persian Gulf is one of the most important and most various aquatic ecosystems in the world due to its location in tropical area. Shrimp trawling is one of the fishing methods in such ecosystem that have high range of by-catch. This study aimed to achieve the percentage of less length frequency of LM50 in three commercially species, namely Pomadasys kaakan, Otolithes rubber and Pampus argenteus in Hormozgan shrimp fishing grounds using shrimp trawl fishery. Samples were taken by shrimp trawl with 2 cm stretched mesh size in codend. The entire operation was conducted by 16 trawling. The largest and smallest individuals trapped by trawling was 520 and 120, 360 and 240 mm total length and 259 and 109 mm fork length for Pomadasys kaakan, Otolithes rubber and Pampus argenteus, respectively. Analysis of length frequencies showed that for P.kaakan 92.85%, P.argenteus 80.39% and O.rubber 73.33 % of total length and fork length of all obtained samples, were shorter than the length were cited in references for LM50 of species. It is suggested to use by-catch reduction device to prevent damage on the stock of these three species in Persian Gulf.

Cadmium is one of heavy metals that naturally are present in crude oil and its derivatives. For the purpose of this study, a total of 120 Carassius Auratus with the average weight of 1.5-2.5 gr. were collected from Goldfish Reproduction and Culture Center in Golestan province, Iran. This study had 5 treatments and 3 repeats for each treatment in dosage of 0, 2.8, 5.6, 8.4, 11, 2 ppm that were 0 (control), 25%, 50%, 75% and 100% of cadmium LC50. At the end of the seventh day one fish of each repeat and lam were sampled for histological study. The results of tissue studies showed mucus, secondary lamella fusion, epithelial lifting, clubbing, shortening of secondary lamella, chloride cell hyperplasia, lamella degeneration and thinning of lamellae. The overall result show that gill tissue was infected during one week exposure to Cd with the increase of exposure time and the amount of poison and that the highest amount of infection was observed in the high poison rate at the end of the week. The findings could be used to evaluate histopathological effects of heavy metals on natural ecosystems within experimental conditional laboratory.

Presence, absence and abundance of fish species in a river ecosystem are affected by various environmental factors. In addition, fishes prefer a specific range of ecosystem habitat factor changes. This study was conducted to assess the habitat suitability indices of Kura Barbel (Barbus ciry) in Taleghan River. For this purpose, the abundance and nine environmental parameters, including depth (cm), river width (m), slope (degree), water velocity (m/s), the average diameter of bedrock, number of stone larger than 25 cm in each quadrat,, index of substrate, percentage of riparian vegetation and percentage of algal cover in 33 stations from downstream to upstream were examined. The results showed that the most suitable habitat parameters for Kura Barbel in Taleghan River are regions with: depth in range of 50-60 cm, river width ranged 0-5 m, water velocity in a range of 0.3-0.6 m/s, slope in range of 1.5-2 degree, the number of large stones (> 25 cm) fewer than 4, the average diameter of bedrock in range of 35-20 cm, index of substrate in range of 5.5-7, algal cover with less than 2% and with riparian forest vegetation. The index of substrate stone had the highest and width river lowest, suitability indices. Habitat suitability index showed that the Taleghan Riveris is an excellent habitat for Kura Barbel.

In this study, the effect of nucleotides added to the diet on the biochemical composition of the carcass and growth factors and nutrition of common carp were investigated. To do so, Nucleotides complement in 3 levels of 0/05, 1, and 1.5 percent was added to the diet and the control group was fed a diet lacking nucleotides. The diets were randomly assigned to a treatment with an average initial weight of fish 4/74±0.2 with 3 replications. After 8 weeks of feeding, the results revealed that most of the dietary treatments was for the group containing %1 nucleotide showing a significant difference with other treatments (P<0.05). In other growth factors, such as weight increase, FCR, SGR, daily growth rate, no significant difference was found (P>0.05). In Chemical Composition of carcass, the highest moister rates was observed in the treatment of 1/5 percent, which was significantly different from other treatments (P<0.05). In other carcass composition, such as fat, protein and ash were no significant differences between treatments (P>0.05). The findings revealed that the nucleotides at 0.05, 1, and 1.5 percent of dietary factors did not affect the growth and carcass composition improvement of common carp, which can be due to the short growth period and also consumption of low amounts of nucleotides. Therefore, in order to achieve better results using higher levels of nucleotides in the common crap diet is suggested.

This study investigated the onion powder supplement in the diet of the Common carp (Cyprinus carpio) on growth, corpse composition and hematological parameters. Twenty fish, averaging 18±1.9 g., were randomly stocked into tanks. Onion powder was added to the basic diet of 39% crude protein and 18% crude lipid at the concentrations of 0, 0.5, 1 and 2%, as four experimental diets. Respectively by hand at a rate of 3-5% of body weight twice daily for 45 days. Blood samples were collected from caudal vein of apparently healthy fish at the end of trial using syringe and hematological indices (WBC, RBC, Hb, PCV, Neurophyl, Monocyte and Lymphocyte) were determined. The optimal growth performance and feed efficiency was observed in fish which were fed the 0.5% onion powder diet despite of no significant difference with the control group (P>0.05). There were no significant differences in survival rate among all groups (P>0.05). Also, no significant differences was observed in crude protein of corpse (P>0.05), while total lipids and ash decreased significantly at the concentrations of 0.5% onion powder (P<0.05). No significant difference in hematological parameters between treatments were found (P>0.05), although the fish fed the 0.5% onion powder diet showed an enhancement of blood variables compared to the other groups. In conclusion, it can be suggested that dietary inclusion of 0.5% onion powder was effective at improving growth, feed efficiency, body composition and hematological parameters of common carp.

Alosa braschnikowii, is abundant Clupeidae fishes in the southern Caspian Sea basin. This study was conducted to compare the morphometric and meristic characteristics of six populations of Alosa braschnikowii in the southern Caspian Sea basin including Miankale, Sari, Tonekabon, anzali, Rezvanshahr and Astara. In total 181 fish from the aforementioned stations (specimens were caught by beach seine in November 2012 from each station) were studied and compared for 33 morphometric and 10 meristic characteristics were examined. The extracted data were analyzed after data standardization using Principal Components Analysis (PCA) and Discriminate Function Analysis (DFA). Univariate analysis of variance and Kruskal-Wallis test among six populations revealed that 32 morphometric characters out of 33 and 4 meristic characters out of 10 characters studied were found to be significant (P≤0.05). DFA revealed that these six populations were distinct from each other in morphometric characters. PCA showed that these six populations are distinct from each other in 6 morphometric characteristics. These differences seem to be under the influence of geographical variation and feed conditions of the fish populations.
