For study on effect of some environmental factors such as bottom structure, depth, dissolved oxygen on density and diversity of bivalves in the Iranian coasts of Gulf of Oman ( Hormoz strait – Gwatr Bay ) 10 stations were selected. A 0.1 m2 Van-Veen grab sampler was used for collecting sediments in addition to the physical and chemical parameters such as temperature, salinity, dissolved oxygen and pH using the CTD device. 95% Ethanol and Rosebengal were used for fixing and staining. In this study, 43 genera of 19 families of bivalves were identified. Lucinidae (55%), Nuculidae (13%), Tellinidae (7%), Veneridae (5%) and Yoldiidae (5%) were dominant groups. Pearson analysis results showed correlation among bivalves abundance and pH , dissolved oxygen and silt ( P< 0.05 ; r = 0.2 ). As far as maximum density is in loamy- silty sediments and there are negative significant correlation among depth and abundance of these (with increasing of depth ,the frequency of bivalves decreases) ( P < 0.01; r = -0.04 ).Results showed that with decreasing of density, diversity increases.

Many pesticides may appear as environmental contaminants once they enter aquatic ecosystem after being used in agriculture. Fish biochemichal parameters are the most common factors which are influenced when aquatic pollution happens. In the present investigation the common caspian bream fish were exposed to sublethal concentrations of diazinon (0.04, 0.36, 0.73 and 1.46 mg/l) in 14 days and its effects on total protein, serum osmolarity and glucose concentration in the blood serum were studied. Results showed that after 7 and 14 days exposure of the fish to sublethal concentrations of diazinon the total serum protein and the serum osmolarity decreased significantly, while the concentration of glucose in fish serum significantly increased (P<0.05). Based on the toxicity of diazinon on serum biochemical parameters of sea bream, its concentration in aquatic environment in Gilan and fish habitat in this environment it is suggested that the pesticide diazinon can adversely affect the growth and survival of fish

According to production of Zinc and Iron oxide nanoparticles and useful application of them in biological systems, less studies on side effects of these materials has been carried out in animals. The purpose of this study was to evaluate the effect of zinc and Iron oxide nanoparticles on the liver and muscles tissues in rainbow trout. For in purpose four hundred and twenty rainbow trout (with initial weight 45±4.7 g) were prepared from a local fish farm and immediately transferred to the laboratory. Immediately disinfect and acclimatized fish to the laboratory conditions for 10 days, then randomly distributed into seven groups. Group one selected as control group that received normal diet and other groups received different amount of 10, 50 and 100 µg/g of nanoparticles a commercial pellet diet for 60 days. To evaluate the tissue sampling was scheduled at the day of 0, 30, 60 and 75 (after 15 days cessation of feeding with nanoparticles). The results of the liver and muscle histological studies with Hematoxilen and Eosine staining showed that in groups which received Zinc and Iron oxide nanoparticles, serious damages in liver hepatocytes including: lipidose, inflammation and disruption of hepatic lobules. Thus it can be concluded that the application of Zinc and Iron oxide nanoparticles in conditions invivo, even in small amounts, had adverse effects on the liver tissue, however the growth parameters were improved in rainbow trout.

The effect of salinity stress on the haematological and serum biochemical parameters of Persian sturgeon (Acipenser persicus) juveniles fed with different levels of Nucleotide-supplemented diet was examined in this study. Fish (42.37± 2.12 g and 23.67± 0.61 cm) randomly were divided to four treatments with different levels of dietary nucleotides (0, 0.25, 0.35 and 0.5 % diet). After 10 weeks feeding, salinity abruptly increased to 12 ppt. Serum biochemical and blood parameters were measured at 0, 12, 24, 48, 72 and 120 hours after salinity stress. One-way ANOVA using the results significantly in the Spss 18 software was used for analysis. Duncan test was used for mean comparing. After 12 hours after salinity stress, control group significantly showed the lowest values of total protein, albumin and eosinophil, and highest value of magnesium while the highest value of albumin found in group fed 0.50 % NT. 24 hours after salinity stress, treatments fed 0.35 and 0.50 % NT, significantly showed the highest values of Hct and RBC. Also the lowest eosinophil was seen in treatment 0.50% (P ≤ 0.05). 48 hours after salinity challenge onset, glucose and MCHC in control group significantly showed the highest values compared to NT-treated groups while there was a significant decrease in calcium as NT level increased. The Mg value, 72 hours later, was significantly higher in treatment 0.50%. Finally, in the last blood sampling (T120), the lowest value of heterophil was found in treatments 0.35 and 0.50 (P ≤ 0.05).

Pheromones are exocrine secretions of the body that has spread from someone around and can cause behavioral responses in other members of the same species. pheromones in mammals often receipt by special organ called Vomeronasal. The main objective of this study was to evaluate the effect of parental and strangers sex pheromones on the puberty beginning in immature male rats. Testing consisted of six groups, each group consisting of 8 rats. In each group male rats were exposed to sexual pheromones from birth. the first group, received maternal pheromones, second group, received the stranger female pheromones, the third group received father pheromones , the fourth group received stranger male pheromones, fifth group received parents pheromones and eventually the six group received strangers male and female pheromones. Immature male rats received pheromones through the ventilator that was placed in the cage. Not found significant difference in testosterone level after hormonal testing in groups. The results of this study indicate pheromones inhaled through the air not have effect on the puberty beginning in immature male rats and it seems pheromones influence puberty beginning in immature male rats if the pheromones directly received by the immature male rats.

Rotifers due to their relatively short lifespan, high fecundity and high rate of population increase are ideal for chronic toxicity tests. Mercury is one of the heavy metals highly toxic to aquatic organismsparticulary freshwater zooplankton of which rotifers are an important group. In peresentstudy, population response of rotifer B. calyciflorus to six different concentrations of mercury (0.0005, 0.001, 0.002, 0.004, and 0.008 mgL-1) with three replicates per concentration was studied for 12 days. Rotifer density and specific growth rate was calculated daily in the control and treatments containing mercury. Result showed that, rotifer population growth decreased significantly (p< 0.05) with increasing Hg concentration in the medium. The maximum density in twelve day belongs to control (45.87±0.07ind/ml) and minimum density belongs to treatments containing concentration of 0.008 mg L-1mercury (6.02±0.03ind/ml). Also, the rotifer specific growth rate decreased significantly (p< 0.05) (from 0.35 in control group to 0.16 in concentration of 0.008 mg L-1) with increasing concentration of this metal. Results of this study showed that rotifers B. calyciflorus are severely sensitive to heavy metal mercury.

Based on the fact that there is little information about natural habitat of the native loach Oxynoemacheilus bergianus, this study was conducted to analyze the habitat range and the preferred habitat of the Safidrud stone loach in Kordan River in the autum 2012. For this purpose, the variables including water depth, river width and slope, altitude, water flow rate and debit, substrate material, over-stream canopy closure, and riparian vegetation type, along with the relative abundance of the interested fish species were analyzed in 66 stations along the river. Based on the results, the habitat use by this species in Koradan River was in altitudes of 1300-1500 meters above sea level, widths of 5-15 m, slopes of 0-49 m/km slope, depths of 6-42 cm, and flow rate of 0.3-1.2 m/s. The highest value of the standardized habitat selectivity indices for Safidrud stone loach in Kordan River were related to the altitudes of 1400-1500 m, widths of 10-12.5 m, slopes of 14-21 m/km, depths of 17-24 cm, and flow rates of 1.1-1.2 m/s. In addition, in the habitats selected, the substrate was gravely, banks had little riparian vegetation cover, and little over-stream canopy closure.

In this study, the status of trophy of Choghakhor wetland was investigated using zoopelanktons. Sampling was performed in 4 seasons and 10 stations since April 2010 to March 2011. Spacing between stations adjacent was considered 1km to each other. Zooplankton sampling was done horizontally (2m) using closing net with an aperture size of 55 microns at depth of 30 cm. Results showed that the most abundant family of zooplankton communities are rotifers (9 families and 16 genera), Branchiopoda (3 families and 5 genera) and copepods (1family and 3 genera). Rotifera was the most abundant taxon in all seasons. Abundant of keratella sp. in spring, Monostyla sp.in summer and autumn and Polyarthra sp. in winter were significantly more than the other species (P>0.05). And also Shannon and Simpson diversity indices in autumn, were significantly higher in comparison with other seasons (P>0.05). The highest level of chlorophyll in summer and fall were 20.92 and 22.63 mg per cubic meter respectively. The annual average of that in the wetlands was determined 75.18 mg per cubic meter, showing that the trophy of wetland was high. In addition, evaluation of trophy indices based on phosphate, nitrate and transparency parameters, demonstrated that trophic state of wetland was in eutrophic condition. Increases in Abundant of Polyathra, Brachionus, Monostyla, Keratella geniuses in this condition can be a sign of eutrophication happening in this wetland.

Herbs have a long history in treating diseases and are usually side effect free. The Aloe vera plant is well known in wound healing in human skin. This study was carried out to evaluate the healing effect of Aloe vera on experimentally wounded Mugil cephalus. For this purpose, four aquaria, each containing six wounded M.cephalus weighting 110±30g were prepared. Fish were anesthetized with clove oil (150 mg/L) and then skin wounds with 5 mm diameter and full thickness and circular shape were created by surgical punch on the left side of each fish biopsy. Aloe vera extract with different concentrations (0.1, 1,2 g/L ) was two times a week in three aquaria and one aquarium was used as a control treatment. Tissue samples were taken from the skin wounds at day 21 after wounding fish fixed in 10% formalin and then processed through routine histological methods. The results showed that fish wounds in the concentration 0.1 g/l Aloe vera were cured after three weeks (P
