The leptin gene has been known as a candidate gene and a key regulator of processes that is related to economic traits. In order to study the polymorphism of Leptin gene, total blood samples were collected randomly from 200 of native and crossbreed cows of Guilan province. DNA was extracted using salting out procedure and polymerase chain reactions (PCR) were carried out using a specific primer pairs for amplification a 522 bp fragment of leptin gene. Amplified fragment was digested by BsaAIrestriction enzyme and then samples were genotyped. For the studied locus Two patterns of A and B were identified with the frequency of 0.455 and 0.545 in native cows and 0.365 and 0.635 crossbreed cows, respectively. Three genotypes of AA, AB and BB with the frequency of 0.19, 0.53 and 0.28 in native cows and 0.14, 0.45 and 0.41 in crossbreed cows were detected, respectively. The chi-square test results showed that the studied populations was in Hardy-Weinberg equilibrium. Nei and Shanon indexes, observed and expected heterozygosities were calculated as 0.496 and 0.689, 0.53 and 0.498 in native cows and 0.464 and 0.656, 0.45 and 0.466 in crossbreed cows, respectively. The results revealed that the marker site of Leptin gene is polymorph in studied cows and the PCR-RFLP technique has a great potential for detection of such polymorphism.

MHC molecules have many important functions related to adaptive immune system in vertebrates andassessment of effects of natural selection and genetic drift on MHC genes diversity of different species are very important. In this study, the MHC genes diversity of native and endangered Caspian trout (Salmotruttacaspius) fishesthat is supported by restocking programs, were investigated. Hence, DAA locus of MHC class-IIα gene became analysis in 50 samples of Caspian trout fishes by SSCP method. Results indicated this gene has at least 15 alleles that MHCScCa-DAA*03 and MHCScCa-DAA*10 alleles have the most frequency. Also, observed heterozygosity (Ho), expected heterozygosity (He) and Shannon index equal to 0.80, 0.82 and 2.037, respectively. In conclusion it must be mentioned, althogh MHC genome of Caspian trout has high allelic diversity, but according to endangered conservational state of this species and human impacts, most of low frequency alleles are in risk of allelic lost. Therefore, the conservation of this genome pool during Caspian trout restocking programs is very critical issue.

Salmonella spp. are enteric pathogen with a worldwide distribution comprising a large number of serovars. Many virulence factors of Salmonella are encoded by located genes on Salmonella pathogenicity islands (SPIs). This study was conducted to investigate the distribution of two SPI-3 related genes in among three serotypes of Iranian salmonella: typhi, paratyphi B and paratyphi C. A total of 25 salmonella strains were isolated from Iranian patients with clinical symptoms of salmonellosis. All isolated belong to salmonella serotypes of typhi, paratyphi B and paratyphi C. Salmonella isolates were screened for the presence of mgtC and misL genes by PCR amplification method. Among 25 salmonella strains, 20 (80%) were positive for SPI-3 region. The presence of misL gene in these serotypes of salmonella was as follows: typhi (100%), Paratyphi C (33%), Paratyphi B (25%) and for mgtC: typhi(97%), paratyphC(33%), paratyphiB(0%). the widely distribution of SPI-3 among Iranian salmonella isolates provide the basic information on the genetic background of virulence as well as molecular properties of three different serotypes of Salmonella. This is the first report on the distribution of SPI-3 in Salmonella isolates from Iran.

Effects of Shaheed Rajaee Dam constructed on the Tajan River on diversity and separation of Spirlin (Alburnides sp.) population was studied. Total of 100 fish samples including 50 samples from either side (below and above) of the dam were caught by electrofishing gear and examined. 53 morphometric were measured with the aid of digital clipper and 16 meristic (numerical) characteristics were also determined in all samples. Principal component (PCA) and detrended fluctuation (DFA) and cluster analyses were used to examine morphometric and meristic (numerical) data following standardization (to avoid error related to alometric growth). The one- way ANOVA analysis for standardized morphometric traits revealed statistically significant differences in 27 parameters within specimens which show relatively high phenotype diversity in A. bipunctatus from two studies areas. The DFA analysis showed that fish population in two areas below and above the dam are separated by 93% in morphometric and 78% in meristic characteristics. The PCA analysis also showed that 8 morphometric and 6 meristic characteristic separate fish populations of the river below and above the dam. The dendrogram constructed by UPGMA based on Euclidean distance coefficient also separated the fish population upstream and downstream of the dam.

At this research it was investigated the effects of three prevalent environmental stresses in Iranian silkworm rearing farms on 6 kinds of Iranian silkworm hybrid performance. The climate stresses included warm/humid, warm/dry and temperature fluctuating conditions which compared with standard rearing climate conditions. The trail carried out within spring and early autumn rearing conditions. Some economic characters such as the percentages of good, middle, low and double cocoons, larval, pupal and total mortality, weight of total and good cocoon per 10000 larvae, number and weight of cocoon per liter, single cocoon weight, single cocoon shell weight and single cocoon shell percentage were surveyed. The obtained results of ANOVA showed the rate of larval, pupal and total mortalities at spring rearing season (3.0, 3.84 and 6.49% respectively) were higher under warm/humid condition compare to warm/dry (2.16, 3.47 and 5.33) and temperature fluctuating (2.22, 4.33 and 6.2) conditions (P˂0.05). Similarly at autumn rearing season warm/humid climate resulted to higher larval, pupal and total mortalities (10.18, 20.66 and 28.07% respectively) compare to warm/dry (5.72, 16.73, and 21.28 %) and temperature fluctuating (3.93, 2.58 and 6.41 %) rearing conditions (P˂0.05). Furthermore at spring and autumn seasons, respectively 2.22 and 6.11 % at larval mortality, 4.07 and 11.0 % of pupal mortality and 5.97 and 16.09 % at total mortality were observed (P˂0.05). According to the results of this study, humidity had no effect of pupal mortality while warm/humid condition increased the larval mortality (P˂0.05). Therefore silkworm hybrids would demonstrate better performance under warm/dry rearing condition compare to warm/humid climate (P˂0.05). Under humid rearing climate the apparent weight of cocoon will increase which is due to higher pupal weight (P˂0.05). The results further showed the existence of negative genetic correlation between resistance and productive characters. It is cleared that the hybrids performances varies based on different environmental condition (P˂0.05).

Fiddler crabs typically live in the tidal muddy and sandy flats. According to the tides play a major role in the distribution of species, this study was conducted in the tidal flat of Rig port in Bushehr in sumer 1391. The more common Ucaannulipes lives in sandy while Ucasindensis lives in muddy areas with sandier sediment. There are differences between the sexes of these two species in field observations. They are also quite different patterns of behavior. However, to compensate for a male crab claws for power supply need to spend more time than the females.The male crabs to be produced larger mud pellets than females.Male fiddler crabs use the major claw to perform a waving display as a form of female courtship.Male fiddler crabs could increase food ingestion by having faster feedingmotions, by feeding for a longer period of time than females, by feeding on largermouthfuls or by having a higher assimilation efficiency of the food they do ingest. Distribution of the Ucasindensis significant increases in very fine grained sand and coarse silt, as well as distribution of the Ucaannulipes considerable increases in very fine silt and coarse clay. Statistical software SPSS was used for data analysis. The aggressive behavior in males can be seen, the behavior of most of the species Ucaannulipes is Ucasindensis.

Nowadays, organophosphorus pesticides such as diazinon are used in various agricultural activities and controlling insects' and pests' control. They could enter surface even underground water sources during drainage process. Diazinon can cause reactive oxidative stresses (ROS) during metabolism process in the body of aquatic organisms. The aim of this study is to investigate the antioxidant effect of vitamin C on antioxidant enzyme activities and lipid peroxidation in Oncorhynchus mykiss. Sixty Oncorhynchus mykiss fish with the average weight of 121 ± 18 g [±SD] were allocated into four treatment groups: (1) control, (2) diazinon (0.1 mg L‑1), (3) vitamin C (300 mg kg‑1 in diet) plus diazinon (0.1 mg L-1) and (4) vitamin C (1000 mg kg-1 in diet) plus diazinon (0.1 mg L-1). After a period of two and four weeks, sampling was performed on their blood serums to measure Superoxide dismutase (SOD) and catalase (CAT) enzymes, total antioxidant capacity (TAC) and malondialdehyte (MDA) index. Findings indicated that the fish in diazinon treated group (without vitamin C in diet) showed significant (p<0.05) decrease in SOD and TAC enzyme activities after two weeks and also increase in CAT enzyme activity and MDA index in the end of fourth week in comparison with control group. The mentioned changes in antioxidant enzyme activity, total antioxidant capacity and MDA index could be attributed to destructive free oxiradicals such as superoxide and hydroxyl radicals produced in diazinon metabolism. In addition, based on our findings, a dose of 1000 mg of vitamin C in diazinon treated fish could cause significant decrease (P<0.05) or balance in CAT and SOD enzyme activity levels and also increase in TAC level and decrease in MDA index in comparison with the group without vitamin. On the other hand, a dose of 300 mg of vitamin C had no effect on decreasing SOD, CAT activity level, but could increase TAC level temporarily in the end of second week and also decrease MDA level in the end of fourth week. In this study, the antioxidant characteristic of vitamin C as a scavenger in removing free oxiradicals produced in diazinon metabolites; moderating antioxidant enzyme activity level, increasing total antioxidant capacity and also decreasing cellular damages caused by destructive lipid peroxidation process in presence of diazinon were reported. Regarding the results and considering the presence of agricultural contaminants, especially organophosphorous pesticides in domestic water sources which are the sources for fish farms, it seems necessary to add vitamin C to diet of cultured species in order to increase antioxidant defense and decrease the oxidative destructions.

This study was conducted to evaluate the use of caraway seeds meal (CSM), as natural feed additives on growth performance and some blood parameters of common carp (2.457±0.057 g). Fish were divided into four groups fed on diets containing CSM in different levels; 0, 0.5, 1, 1.5% and the experiment extended for ten weeks. The CSM supplementation enhanced significantly fish growth over the control diet (P<0.05). Results showed that fish fed diets containing 1 % CSM had significantly higher growth performance (weight gain, gain % specific growth rate (SGR) and the lowest fish growth was obtained at control diet. Feed conversion ratio (FCR) decreased significantly in diet containing 1 % CSM (P<0.05). WBC levels decreased significantly in fish fed with dietary caraway compared with control treatment (P>0.05).There is also no significant difference between RBC, HCT and HGB in experimental groups (P>0.05). In addition, there were significant differences between biochemical parameters in fish fed with dietary caraway compared with control treatment (P<0.05). The highest levels of glucose and cholesterol were observed in control treatment and the highest level of total protein was observed in diet containing 1 % CSM. The results of this study show that addition of caraway to fish diet can promote growth and improve fish health.

The understanding of the species habitat requirements and parameters affecting the habitat selection would be essential for sustainable coservation. The black-beilled sandgrous (Pterocles orientalis) occurs in some southern plains of Sabzevar including Shir-Ahmad Wildlife Refuge. Although it suffers intensive habitat destruction and hunting, still there is no enough information about its population ecology in this distribution area. The study area was surveyed for recording presence and absence sites of bird. Using logistic regression analysis the association between species presence/absence and habitat parameters was examined. It was found that vegetation height, height of tallest shrub, canopy cover percentage, stony coverage, distance to roads, distance to water resource, altitude and slope, negatively and ant nest occurring, gravel percentage and stone number ,positively, in assessment plots are significantly associated with the black-beilled sandgrous presence (p<0.05).

In present study, Rhabdochona denudata parasite for the first time was reported from sand goby in Iran. Range of number Rhabdochona denudata was 1-33 specimens. The relationship between age and Rhabdochona denudata infection (prevalence) showed significant, in three Streams (p<0.05). So that was positive in Kaboodwal and Zarrin-gol and negative in Shirabad Streams, but no significant relationship between infection level and sex of sand goby (p>0.05). It seems that the presence and abundance of Ephemeropterans and Trichopterans nymphs as intermediate hosts of Rhabdochona denudata and feeding rate of them can be role in the rate of infection, So that, the most parasitic infection associated with the highest frequency of Ephmeropterans in environment and gut sand goby was observed in the Shirabad Stream.

Numerical index of diversity, Combination of species richness and evenness are two important components But one of the Important problems of This indexes is this Do not separate the contributions of these two components is the numeric index value. One of the most effective and efficient methods to compute Contribution of these two components is the numeral diversity of SHE analysis The method of calculating the two components permits. This review is from mid- winter census water birds of Hasan langhi(Namaki), kolahi and tiab estuaries During the six years(1385-1390) In order to clarify Factors influencing the Numerical index of diversity was used. Calculation of diversity indices showed The variation in tiab, Hasan langhi and kolahi estuaries In order to 1388,1388,1389 Higher than other years, Shannon Wiener diversity index, Pielou J Richness index was the same frequency as and Evenness index, where (H'=3/15),(44) and (j'=0/75);( H'=3/2),(41) and (j'=0/79);( H'=2/99),(37)and(j'=0/74) Respectively. The results indicate that the factors influencing the numerical index variation is uniform in all three components of the estuary. In this period of intense change the landscape for birds Been observed in three assorted which means that the species composition have been relatively consistent.

This research aims to study the heavy metal accumulation of Pb, Ni, Cu, Fe, and Zn in muscle, gill, liver, and kidney tissues of Snow trout (Schizothorax zarudnyi) from Chahnime Water Reservoirs of Sistan. After sampling, preparation, and digestion using nitric acid, the concentration of each metal was measured in µg/g-1 dry weight using Atomic Absorption Spectrometry (Konic NOVAA300). The results of this study showed that there is a significant difference between heavy metal concentrations in different Snow trout tissues (p<0.05). The heavy metal accumulation pattern in different tissues of this specie was Fe>Zn>Cu>Pb>Ni. Also, it was found that the metal accumulation amount of Pb, Ni, and Cu in the muscle tissue, which is the edible tissue, is higher than the limits set by global standards like WHO, FDA, FEPA, and NHMRC. Also, Zn concentration was higher than all of the mentioned standards except NHMRC which most certainly threatens the fish and human health.

To determination the toxic effects of atrazine on Caspian kutum, the 96-h LC50 of atrazine was measured for newly hatched larvae as 18.53 ppm. Toxicity of atrazine herbicide on Caspian kutum larvae was investigated using concentrations: 9.25ppm, 4.62 ppm and 2.31 ppm for 7 days. Comparison of the length, weight and condition factor showed that no significant differences between atrazine exposed and control groups. The concentration of Na+, K+, Ca2+, Mg2+ and Cl- in whole body of larvae in control and atrazine exposure groups were measured and the results showed that concentrations of all these ions is higher in atrazine exposure group than control group. Results of the present study showed that atrazine could affect the ion compositions of the body even at sublethal concentration and acute exposure but at this kind of condition have no effects on growth parameters of the body.

Recent findings demonstrate that oligomeric species, as toxic intermediates during the formation of mature fibrils, by increasing membrane permeability leading to cell death. Among these, the membrane of interest is mitochondria, so that mitochondrial dysfunction is a common feature of many disorders relating to protein aggregation. Therefore, in the present study interaction of the original native structure, oligomeric intermediates and amyloid fibrils of hen egg white lysozyme (HEWL) with mitochondrial membranes (as an in vitro biological model) were investigated. First structural characteristics of prefibrillar intermediates have been investigated using a range of techniques including fluorescence (ThT and ANS) and circular dichroism, and possible mitochondrial membrane permeabilization was determined following release of marker enzymes. Results presented demonstrate release of mitochondrial enzymes upon exposure to HEWL oligomers, whereas native monomer or mature fibrils were totally ineffective. It seems that increased surface hydrophobicity of HEWL oligomers enhanced their capacity to interact with mitochondrial membranes. Then we investigated the ability of Resveratrol to counteract mitochondrial membrane permeabilization induced by HEWL oligomers. The results demonstrate that Resveratrol can effectively hinder oligomer-mediated mitochondrial permeabilization. It has been suggests that Resveratrol via its membrane stabilizing effects protects mitochondria against oligomer toxicity. These may serve for design of novel therapeutic agents against disorders relating to protein misfolding and aggregation

The aim of this trial was to evaluate the effect of gamma radiation on growth and hematological parameters of rainbow trout (Oncorhynchus mykiss) larvae. In this research, Rainbow trout of eggs were irradiated by low (1, 2.5, 5Gy) and high doses (10, 20, 40 Gy) of gamma radiation. After 90 days, the growth and survival eggs and blood parameters of larvae was investigated. The result showed the negative effects of a gamma ray, as the increase in levels of radiation caused a significant decrease in the growth and survival of all treatments. Eggs exposed dose 40 Gy of gamma radiation, destroyed. The highest rates of growth and survival obtained in the control treatment and increased radiation levels, brought about significantly decreased on mentioned parameters. A decreasing trend in blood parameters was observed when the radiation levels increased. In all treatments, levels of RBC (red blood cells), Hct (hematocrit) and Hb (hemoglobin) declined significantly (P<0.05) as the irradiation levels increased, where as the amount of MCV (Mean corpuscular Volume) and MCH (Mean corpuscular hemoglobin) not changed. Also the levels of white blood cells (WBC), lymphocytes and monocytes, decreased, that this reduction was not significant (P<0.05). The results suggest that gamma rays can be a potential candidate for damage cells, resulting in decreased of growth and survival of eggs and larvae of hematology of rainbow trout.

* Corresponding Author’s email: Hrnaderi68@yahoo.com The broccoli plants (Brassica oleracea gemmifera L.) are full of organic and mineral matters and vitamins. The presence research was studied on the effect ofdifferent levels (0%, 0.2%, 0.5% and 1% respectively) of broccoli on hematological and biochemical parameters and growth of common carp (Cyprinous carpio). 300 fish (25 fish per tank with an average body weight of 2.11±0.24 g) were dieted for 8 weeks. The result showed that white blood cell count (WBC), total protein (TOP) and globulins (GLU) increased significantly in treatmeant group with 0.5% broccoli in comparison with the other groups (P<0.05). However, the amount of red blood cell count (RBC), hemoglobin (Hb), Hematocrit (Ht) and eosinophil in all the treatment groups increased than the control group with no significant difference (P>0.05). In relative of growth indices, the amount of Protein Efficiency Ratio (PER), Body Weight Index (BWI), Food Efficiency (FE) and Growth Rate (GR) between treatment groups were increased in comparison with the control group but, not significantly (P>0.05), but the amount of Specific Growth Rate (SGR) at the treatment with 0.2 percent in comparison with the control group showed the significant difference (p<0.05). In the end, we can conclude that it seems that 0.5% of broccoli in the diet can have a better effecton hematological, biochemical parameters and growth indices and increase the growth, immune system and health of the fish.

In the present study the morphologic traits of Leuciscus orientalis (Nordmann, 1840) populations were examined in the Doogh River, Siahroud River and the Sefidroud River in the Southern Caspian Sea basin. A total of 190 fish specimens were collected and 25 morphometrics, 5 proportional morphometrics and 9 meristic characters were recorded. Existence of sexual dimorphism was confirmed in all populations by t test analysis on morphometric features. Pupil diameter, postdorsal distance, length of anal fin base, interorbital distance and head width were significant different between male and female specimens (p<0.05). Despite of similar meristic characters among populations, Doogh population has more connection to Siahroud population based on taxonomic distance of morphometric traits rather than Sefidroud population. PCA revealed that first and second componants cause 69.77% of total variance of differences. In order to show clear relation of populations CVA/MANOVA analysis has been applied. The results showed that all populations separate significantly (Wilk̍s lambda= 0.052, p<0.05), first and second canonical includes 66.8% of total variance. Coudal peduncle width, pectoral fin base and eye diameter were loaded on first canonical and inter-orbital distance, pupil diameter and length of anal fine base were loade on second canonical.

The present study was performed to elucidate the probable effects of prebiotic Mannan Oligosaccharides supplementation in diets on growth performance and feed efficiency of rainbow trout fry. 1500 fish with average weight of 110±10 mg were distributed into 12 (35 L) tanks (125 fish/tank) and cultured for 60 days using experimental diets. Fish diet was used by prebiotic supplementation at three levels of 0.5, 1, and 2 g/kg along with a control diet. The results showed that final weight significantly increased in fish fed 0.5, 1 and 2 g/kg (Final weight: 2.03±0.11, 2.61±0.69 and 2.57±0.04 gr, respectively) Mannan prebiotic supplementation were significantly higher than the control group (Final weight: 1.67±0.05 gr). However, feed conversion ratio in fish fed 0.5, 1 and 2 g/kg Mannan prebiotic supplementation were significantly lower than the control group (P<0.05). The use of 1g/kg dietary Mannan Oligosaccharides prebiotic improved the growth parameter and feed efficiency ratio in rainbow trout fry.

Samples were taken from the Babol-rud, Baleqlu-Chai, Miriseh, Gamasiyab and Mahabad-Chai rivers in Iran during May 2010 to October 2012 by electrofishing. A hundred five truss distances between 15 landmarks in 300 specimens were measured. The ANOVA revealed significant differences in all the 105 morphometric factors (P<0/05). Principal component analysis (PCA) for morphometric data showed that 14 factors of the first morphometric characters among the 105 factors established had 96.33% changes in 5 species studied. Plotting the first and the second canonical discrimination analysis showed that A. atropatenae, A. filippii and A. mossulensis were high overlapping with each other, and A. hohenackeri andA. chalcoides were through separated from the others. The dendrogram derived from cluster analysis of Euclidean square distances among groups of centroids showed that the five species of the genus Alburnus were partly distinct from each other with respect to morphometric characters.

Cortisol plays an important role in several aspects of fish physiology including ionic and osmotic regulation, growth, stress and immune function. This study conducted to evaluate the long time effect of oral cortisol on the growth performance, survival, biochemical blood parameters in common carp (cyprinus carpio) fingerling. For this purpose, common carp (1.36 ± 0.12 g) was distributed in 4 treatments in 3 replicates and fed with commercial food containing 0 (control), 50, 100 and 200 mg kg-1 food hydrocortisone during 8 weeks. This results showed that no significantly difference in growth performance (growth rate (GR)), specific growth rate (SGR), feed conversion ratio (FCR), Feed intake (FI), survival and hematocrit between treatments (p>0.05). Serum glucose levels in control treatment (73.04±1.40mg/dl) was significantly lower than other treatments by serological investigation (p<0.05) but no significantly difference in serum calcium Ionic factor between treatments (p>0.05). Serum total protein in fish fed cortisol were significantly lower than the control group (p<0.05). The results of this study showed that oral administration of cortisol can increase blood glucose as an energy source for the mechanisms of osmotic in the common carp fingerling.

In this study the ability of adaptation and growth rate of salt water fish (Scatophagus argus) in freshwater environment were investigated. This fish naturally lives in salinity between 16-20 ppt. Four treatments of salinity (0-10-20 and 30 ppt) in 3 replicates and per replicate including 6 fish were selected. After the adaptation period, from each treatment, one fish randomly selected and the methods of tissue sections prepared and stained (hematoxylin - eosin) was performed on organs of kidney and gill. The results of the microscopic changes in chloride cells were examined. Based on the results of specific growth factors increases, obesity rates and the percentage of survival of juveniles in different treatments did not show significant difference (p>0/05). The highest specific growth rate and the lowest rate of obesity were found in the salinity of 20 ppt and 30 ppt, respectively. The highest percentage survival and the survival of juveniles was observed at salinity of 10 ppt. Survival rate of fish in fresh water was same with the salinity of 20 ppt that is suitable salinity for Scott Fish in the environment. During the examination period, the photograph was taken from the tissues of kidney and gill by light microscope. After counting the gill chloride cells and of kidney it was clear that with the reduction of salinity, chloride cells of gills decrease and of kidney were increased )P<0/05).

In order to ponder the abundance, distribution and diversity of fish and relationship to environmental factors were studied in the Tilabad stream, from summer 2009 to spring 2010. Specimens were caught by electrofishing (DC, 200-300V). Results show that three species of fish have been identified including: Spirlin (Alburnoides eichwaldii), Capeta (Capoeta capoeta) and loaches (Paracobitis malapterura). The estimated population was calculated as for density in different seasons. Capoeta and spirlin was caught the highest frequency in all four seasons so that Capoeta were dominant species (P<0.05). In Tilabad stream, the presence of Spirlin was positive and significant correlation with the amount of vegetation and channel insection and Capoeta had the highest positive correlation with turbidity and stream width and also the presence or absences of Loaches were positive correlated to riffle (P<0.05).

The 800 species of echinoids alive today, coupled with the wonderful fossil record, make the echinoids excellent candidates for a great variety of studies, from reproductive biology to evolution. The irregular echinoid Clypeaster Lamarck is locally common in Oligocene to Quaternary sedimentary deposits in the Caribbean region. Clypeaster, seen from the post-Eocene epoch. Clypeaster humilis; is such a class of Echinoidea that this species seen in the Persian Gulf but Iranian waters. This species resembles C. humilis (LESKE, 1778) a living species of the Persian Gulf in Arabia coastal and Red Sea but the present paper recorded from Hendorabi Island for the first time. The species is widely distributed in tidal and shallow waters of tropical and subtropical regions. Clypeaster humilis, ranging from the Persian Gulf, in depth of sandy-soft sediments to about 10-15 meters.

* Corresponding Author’s email: gharedaashi.e@gmail.com The aim of present study was to determine the LC50 value of copper and lead and effect on behavior and gill texture in Caspian Sea kutum. First For determination of the LC50 (lethal concentration) values, Following a range finding test, eight Cu (0.5, 0.75, 1, 1.5, 2, 2.5, 3 and 3.5 mg/L) and Pb (100, 200, 220, 240, 260, 280, 300 and 320 mg/L) concentrations were chosen for Caspian Sea kutum. For each metal-treated and Control tree replications were conducted. The results indicated that median lethal concentration (LC50) of copper to Caspian sea kutum (Rutilus frisii kutum) for 24, 48, 72 and 96 h of exposure are 2.944, 2.756, 2.562 ppm and 2.310 ppm respectively and median lethal concentration (LC50) of lead to Caspian sea kutum (Rutilus frisii kutum) for 24, 48, 72 and 96 h of exposure as 315.841 ppm, 298.456 ppm, 281.419 ppm and 268.065 ppm respectively. LC50 increased with decrease in mean exposure times for both metals. The behavior of fish remarkably changed due to the treatment of lead and copper when compared to the control. The various locomotary responses exhibited by fish due to sub lethal concentrations of lead and copper during initial stage of exposure included restlessness, erratic and fast swimming, abrupt change in position and direction, jumping and overall hyperactivity were noticed. The fish showed surfacing tendency throughout the experimental period. Thereafter experiment for determine the growth performance fish were kept in the aquaria containing sub-lethal concentrations of copper sulfate (0.11 and 0.23 mg L-1) and lead nitrate (13.4 and 26.8 mgL-1) grown for 60 days, while control fish were placed in metal free water. The chronic sub-lethal water-borne Cu and Pb exposure to the fish exerted that larvae had significantly decreased final body weight in comparison to control treatment. The Cu and Pb also had significant negative effects on specific growth rate (SGR). Hence, concluded that copper is more toxic than lead for Caspian Sea kutum (Rutilus frisii kutum).
