Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six food treatments comprising a commercial feed, non-enriched Artemia nauplii and the nauplii enriched by either of fish, sunflower, canola and soybean oils were used in triplicates. The fish fed with Artemia enriched by fish, sunflower and canola oils had significantly higher (p < /em><0.05) survival rate, total length, wet and dry weights, specific growth rate and lower food conversion ratio than those fed the commercial feed. However, there were no significant differences in growth indices between the fish fed fish oil-enriched and plant oil-enriched Artemia. Minimum eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were reported in the fish fed with the commercial feed, while maximum EPA and DHA were in the fish fed canola oil-enriched and nonenriched Artemia, respectively. The fish fed canola oil enriched Artemia had significantly higher (p < /em><0.05) resistance against environmental stresses compared to fish fed the commercial diet. Results showed that the plant oils, mainly canola and sunflower oils can be used for Artemia enrichment as a suitable substitute for the more expensive and rare fish oil for improving growth and resistance to environmental stresses in rainbow trout larvae.

Monthly samples of Acanthopagrus latus (Hottuyn, 1782) were used to determine (1) feeding habits and (2) reproduction characteristics of the species in relation to its size, spawning season and sex in the Northern part of the Persian Gulf from January to December 2013. The smaller length classes of all samples were dominated by male fish. All gonads examined, were ovotestis during the spawning period from February till May. Male and female ovotestes were dimorphic in structure which represented a transitional stage in a protandrous sex change. Length at first sexual maturity of female A. latus was 24.40 cm. A. latus fed predominantly on bivalves, gastropods, cephalopods, stomatopods, fish and decapods which showed changes according to the season and body size. According to our results, it appears that A. latus feeds throughout the year; the highest value of gastrosomatic index (GaSI) for both sexes was recorded in February, which was significantly different from that in other months. The results of this study also indicate that feeding in yellowfin seabream is very intense before reproduction (during January and February). It decreases gradually after February to June during the spawning season.

In the present study, the effect of successive milt collection was investigated on spermatological parameters and reproduction successes of wild and cultured endangered caspian brown trout. The milt collection was done 3 times with two weeks intervals. After milt collection, amount of milt was allocated for milt quality evaluation and reminders used for fertilization. According to results, in wild fish, the values of fertilization rate, eyeing rate, hatching rate, milt volume and duration of sperm motility decreased during successive stripping (P<0.05) while the spermatocrit, sperm density did not show significant differences (P>0.05). Also, the percentage of abnormal spermatozoa increased during successive stripping in wild fish (P<0.05). The perm density, spermatocrit and survival percent of larvae did not show significant changes during successive stripping (P>0.05). In cultured fish, similar results were observed about fertilization rate, milt volume and duration of sperm motility (P<0.05), although the eyeing rate, hatching rate, spermatocrit and sperm density values did not show significant changes during successive stripping (P>0.05). Also, the survival rates of larvae were statistically different between second and third stripping (P<0.05). In conclusion, our results showed that the successive milt collection has a significant influence on milt quality and reproductive efficiency of male caspian brown trout, with the best milt being available at the first stripping.

The present investigation aimed to evaluate the effect of turmeric on shelf life extension of shrimp Penaeus semisulcatus under chilled storage conditions by sensory (organoleptic parameters), pH, proximate and bacterial analysis. The experimental setup was grouped into six, head on (group I), head on coated with turmeric (group II), headless (group III), headless coated with turmeric (group IV), peeled (group V) and peeled and coated with turmeric (group VI) groups. Peeled shrimps coated with turmeric group retained their quality and their shelf life was extended up to 8 days of storage in ice (1:1). Significant differences (p < /em><0.05) were found in the overall acceptability among the experimental groups of fresh and cooked shrimp. The level of pH, protein and carbohydrate varied (p < /em><0.05) among the experimental groups. However no significant difference was found in the lipid and bacterial level in peeled shrimp coated with turmeric on the 8th day compared to other groups including the control. The sensory analysis, pH, protein, carbohydrate, lipid and bacteriological results of the present study proved that the application of turmeric in peeled shrimp stored in ice (1:1 ratio) extended its shelf-life up to 8 days..

Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration in aquaculture waste. In this study, the agarophyte Gelidium elegans originating from Korea was investigated for bioremediation of tiger shrimp (Penaeus monodon) broodstock effluent (SBE) in a shrimp hatchery in Malaysia. The G. elegans was cultivated in SBE using a semi-continuous culture system to evaluate the effects of elevated nutrients on the biomass, growth rate, quality and quantity of agar, pigment content and biochemical composition of seaweed. In the treatment containing G. elegans, pollutant nutrient concentration was reduced by 100%, and by 78.7%, 47.9%, and 19.6% for ammoniacal-nitrogen, nitrite, nitrate, and orthophosphate, respectively. The seaweed grew well (1.4 ±0.3% d-1) in SBE and produced appreciable amounts of protein (3.8% DW), carbohydrate (41.4 % DW) and agar (25.9% DW), that were significantly enhanced when cultured in the SBE compared to control. The photosynthetic performance of G. elegans assessment using a Diving-PAM showed the healthy condition of the grown seaweed without any indication of stress in shrimp hatchery effluent. Results showed that G. elegans has biofiltering and bioremediation potential for the shrimp hatchery effluent.

The sailing tracks of single otter trawl vessels were simulated using cubic hermite spline (cHs) interpolation method based on the automatic identification system (AIS) data of 6 sampled vessels that were fishing in the Zhoushan fishing grounds after the close of the fishing season from September 2012 to January 2013. The vessels’ status (i.e. whether the vessels were fishing or not) were determined based on the integrated information of speed method and the simulated tracks. Generalized additive model (GAM) was built according to the logbook data of the 6 vessels in 2010, and then the GAM was applied to the AIS data of the same 6 vessels from September 2012 to January 2013 to estimate the monthly catches of these vessels in this period. The results show that the error of the simulated tracks increase with the increase in time interval, and the time interval of AIS data should be shorter than 30 minutes to prevent low accurate results. GAM can give viable estimates of catches when they do not greatly fluctuate over years. The step-by-step GAM analyses indicate that the factors, which affect catch, are ordered by their importance as date, sea surface salinity (SSS), latitude, sea surface temperature (SST), sea surface height (SSH) and longitude. This research is a new attempt for the study of fisheries resources in China using new data sources, which will be helpful for the improvement of fishery research in such data-poor countries as China.

The objective of this study was to determine the effect of different concentrations of anolyte on saprolegniasis in comparison with green malachite in rainbow trout hatcheries, in the northern part of Iran, Tonekabon. Nearly 5000 green eggs of Oncorhynchus mykiss (equivalent to 300 g) were obtained from a private farm in the north of Iran. The study was designed in 5 treatments, 0.25, 0.5, 30 and 100 ppm of neutral anolyte and 2 ppm of green malachite and two controls including positive control, meaning that the green eggs were purposely infected with saprolegnia but without any disinfectant, and negative control, which was implied to as the untreated group, all in triplicate. There was no significant difference (α>0.05) in hatchability percent between 2 ppm of green malachite and the group treated with 0.25 ppm of neutral anolyte, contrary to other anolyte concentrations. It is concluded that constant use of 0.25 ppm of neutral electrolyzed oxidized water (NEOW) is a more effective anti-fungal solution with the least side effects in comparison with 2 ppm of green malachite.

Squid (Loligo loligo ): The new source to extract omega-3 and omega-6 rich marine oils
Y.A Asadpour
asaddnazlo@yahoo.com
1
Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferred to Urmia Research Center for further action. Extracting oil from squid was done by using the Dyer and Bligh standard method. The results indicated that 13±5% of wet weight of squid was oil; the percentage and profile of the extracted oils were made by using the G.C method. The results showed that squid oil had 29.40% saturated fatty acids and 23.70% single- band unsaturated fatty acids, and the total value of the unsaturated multiple-band fatty acids of the same was 40.20%. Also the contents of arachidonic acid was 2.78%, linolenic acid was 3.10%, linoleic acid was 5.20%, docosahexaenoic acid (DHA) was 15.40%, and eicosapentaenoic acid (EPA) was 9.60% of the total fatty acids. The results demonstrate that squid is considered for the first time as the new and rich source of Omega-3 and Omega-6.

The invasion of Spartina alterniflora significantly affected the local ecosystem of Western Pacific Ocean where Moerella iridescens lives. Five patches with different invasion stages of S. alterniflora were selected and the influence on distribution of
M. iridescens was studied on the coast of Wenzhou Bay, China in 2007. The aggregated distribution pattern was proved by using Taylor's power regression and Iwao's plot regression methods (p < /em><0.001). The densities were significantly affected by the factors of S. alterniflora invasion stage and season (p < /em><0.001), but no significant effect of interaction (p < /em>=0.805) occurred. M. iridescens mainly clumped in the habitats of no invasion and initial invasion of S. alterniflora was in the high tidal zone, and the lowest density was recorded where complete invasion occurred. The densities were larger in warmer than in cooler seasons. There were significant positive correlations among the average densities in seasons. Density variation must be the response of M. iridescens to the environment, including S. alterniflora invasion stage, temperate stress and interspecific associations.

The zooplankton community structure in Eğirdir Lake (Isparta-Turkey) was studied monthly throughout an annual cycle (January 2010-December 2010). The zooplankton community was represented by three main groups: Rotifera, Cladocera and Copepoda, respectively comprised 89.62%, 7.78% and 2.60% of the total zooplankton abundance. Eğirdir Lake was dominated by the rotifera Polyarthra dolichoptera in September and October, that succeeded by cladocera Bosmina longirostris species during December. Canonical correspondance analysis (CCA) was used to relate species distribution to environmental factors. The variation in the species data was significantly (p < /em>< 0.05) related to a set of environmental variables (conductivity, carbonate, pH, ammonium, organic substances, dissolved oxygen, saturation of dissolved oxygen, chloride and temperature). According to the CCA result, variables were able to explain 81.9% of the total variation suggesting a significant result. The rotifer, Asplanchna priodonta, and the crustaceans, B. longirostris and Nauplius larvae seemed to be affected by environmental gradients.

The aim of this study was to assess the influence of trout farm effluents on water quality parameters in the Dohezar Stream. In this study two trout farms and 7 stations were selected and physiochemical of water, including air and water temperatures, dissolved oxygen concentration (DO), pH, electrical conductivity (EC), water flow and biochemical oxygen demand (BOD) were measured every 30 days for one year. A combined total of 60 benthic macroinvertebrate taxa were collected from the seven sites of the stream. The results showed that trout farms had a significant impact on EC, pH, water flow and BOD in the water throughout the year and among stations (p < /em><0.05). Only DO did not show significant differences in the one year survey. Macroinvertebrates had significant differences in abundance downstream from the trout farm effluent, particularly in stations 1 and 3 compared with others. However, the diversity of benthic macroinvertebrates significantly decreased, particularly in stations of 3, 4 6 and 7. Regarding benthic macroinvertebrates, the abundance percentage of ephemeropterans, plecopterans and trichopterans (expressed as EPT %), and Biological Monitoring Working Party (BMWP) were much lower in station 3 than in other stations.

This experiment was conducted to investigate the effects of various starvation and refeeding periods on growth, feed utilization and body composition in Asian sea bass (Lates calcarifer) with an average initial weight of 30.26±1.4 g (mean±SE). The fish were exposed to three different regimes: the control group fed twice daily to apparent satiation throughout the experiment (C), the first group starved for 4 days and refed for 16 days, this cycle was repeated two times (T1) and the second group starved for 8 days and refed for 32 days (T2). At the end of experiment, there were not any significant differences in growth and feeding performance among different treatments (p < /em>>0.05). Daily feed intake was significantly higher in the deprived fish than in the control fish (p < /em><0.05). There were no differences in moisture, lipid, ash and nitrogen free extract (NFE) content of carcass at the end of different starvation and refeeding periods between the deprived and control fish (p < /em>>0.05). Starvation had a significant effect on protein content on one sampling date during the experimental period; protein content in T2 on day 8 was significantly lower compared to the control (p < /em><0.05). Sea bass showed complete compensation indicating a high ability of the deprived fish to grow sufficiently to fully compensate for weight loss during starvation. The results suggested that the feeding schedule involving starvation-refeeding cycles could be a promising feed management option for the culture of this species.

Cryopreservation of seabass (Lates calcarifer) semen is an approach to increase the quantity and quality of seabass fry in aquaculture. However, cold shock can induce sperm injury leading to structural damage of the plasma membrane and loss of motility. Thus, the effect of cryopreservation on fatty acid composition and antioxidant enzyme activities of seabass sperm was determined. In cryopreserved spermatozoa, the proportion of C16:0 was significantly increased (p < /em>=0.05), while the proportion of C23:0, C22:6 n3, C22:5 n6, and C18:1n9t decreased significantly after freeze-thawing compared with that in fresh semen (p < /em>≤0.05). The relative content of saturated fatty acids significantly increased (p < /em><0.05) but that of polyunsaturated fatty acids decreased (p < /em>=0.05) in cryopreserved spermatozoa. Consequently, the ratio of unsaturated/saturated fatty acid was greatly decreased in frozen sperm (p < /em><0.05). Superoxide dismutase and glutathione peroxidase activities in frozen-thawed sperm increased significantly while activity of catalase did not differ at p < /em>>0.05. Malondialdehyde levels increased after cryopreservation compared to fresh semen (p < /em>=0.05). These results indicated that an increase in superoxide dismutase and glutathione peroxidase activities in cryopreserved spermatozoa did not efficiently scavenge reactive oxygen species leading to an increase in lipid peroxidation, a reduction in polyunsaturated fatty acids and finally irreversible loss of sperm motility.

Effects of dietary synbiotics on growth performance, survival, stress resistance, body composition and immune response in the Caspian roach (Rutilus rutilus) were evaluated. Fish with an initial average weight of 4.14±0.25 g were randomly distributed into tanks (50 fish per tank) and triplicate groups were fed a control diet or diets containing 1 g kg-1 and 2 g kg-1 synbiotics. After an 8-week feeding period, a general enhanced growth performance and feed efficiency were observed in fish fed on the diet containing 2 g kg-1synbiotics (p < /em><0.05). Subsequently, immune responses (Ig levels, lysozyme activity and ACH50) were significantly higher in 2 g kg-1 synbiotics fed fish (p < /em><0.05). Although all levels of dietary synbiotics significantly increased resistance to a salinity stress challenge (p < /em><0.05), the highest survival rate was observed in this group. The intestinal tract of the fish with synbiotic diet supplementation had higher concentrations of lactic acid bacteria (7.13±0.32 log CFU g-1). The protein and lipid contents in the whole body increased in the 2 g kg-1 synbiotics fed group. At the end of experiment the fish fed synbiotics had the highest survival index after 40 hours exposure to salinity stress (13.8 ppt). Results showed that the addition of synbiotics to the diet of Roach (Rutilus rutilus) stimulates the beneficial intestinal microbiota and alters their immune defense system.

Effects of Artemia urmiana enriched with ICES30/4 as a commercial emulsion of highly unsaturated fatty acid (HUFA) on growth, survival, salinity tolerance and fatty acid composition of the Persian sturgeon larvae were evaluated. Artemia enriched for two different time periods (12 and 24 hours) and non-enriched artemia were fed to A. persicus larvae (average initial wet weight 46.80± 2.03mg) during 20 days. The n3-HUFA content ranged from 0.82±0.08 mg /g DW in non-enriched artemia to 7.69±0.2 mg/g DW in enriched artemia during 24 h with ICES30/4 and ranged from 3.20±0.30 mg/g DW in sturgeon fish larvae fed with non-enriched artemia to 5.98±0.43 mg/g DW in fish larvae fed with 24 h-artemia enriched with ICES30/4 after 20 days. The n3-HUFA content significantly increased compared to 12 h enrichment period both in artemia and sturgeons fed with these artemia (p < /em><0.05). A significant increase in survival percentages and salinity tolerance were observed between fish larvae fed with enriched and non-enriched artemia (p < /em><0.05), while growth rate did not significantly differ among the treatments (p < /em>>0.05).

The effects of substituting dietary protein sources with different levels of Sargassum ilicifolium on growth, survival and body composition of rainbow trout Oncorhynchus mykiss were investigated over the course of a 60 day experiment. A total of 360 juveniles (75±2.8 g) were randomly allotted to four treatment groups including (control: with 100% basal diet (BD); T1: 5% sargassum meal (SM)+95% BD; T2: 7.5% (SM)+92.5% BD and T3: 10% (SM)+90% BD. Each treatment group was divided into three replicates of 30 fish per replicate. At the end of the experiment, our results showed that replacement of 5% and 7.5 % of basal diet with sargassum meal showed significant differences in average weight and total length, feed conversion ratio (FCR), specific growth rate (SGR), weight gain percent (WG), condition factor (CF) and survival rate (SR). There were significant differences between calorie content of carcass in T2 and control with T1 and T3 (p < /em><0.05). The highest values of carcass protein content were observed in T1 (p < /em><0.05). There were significant differences between lipid content of fish in T2 and control with that of fish in T1 and T3 (p < /em><0.05). The highest values of carcass ash content were observed in T1, (p < /em><0.05) which were not significantly different from that in other treatments (p < /em>>0.05). Levels all of amino acids were higher in fish in T2.

The objective of this research was to evaluate yield parameters (gained weight, weight percentage, survival, feed conversion factor (FCR), feed conversion efficiency (FCE), condition factor (K), specific growth rate (SGR) and hepatosomatic index (HSI) of trouts fed with experimental diets elaborated with bean (Phaseolus vulgaris L.) flour instead of fishmeal with 15, 30 and 45% (BF15, BF30 and BF45, respectively) for 32 days, as well as a control diet (CD). The greatest weight gain was presented by fish fed with BF15 and BF30 (14.48 and 14.14 g, respectively) with no significant differences (p < /em>>0.05) and an approximate increase of 50% of their initial weight. FCR did not show significant differences (p < /em>>0.05) among CD, BF15 and BF30 diets with an average value of 2.05. FCE did not show significant differences (p < /em>>0.05) between diets BF15 and BF30 with an average value of 46.70%. SGR did not show significant differences (p < /em>>0.05) between BF15 and BF30 diets with an average value of 1.25. It is concluded that 30% is the maximum substitution without causing a decrease in yield and nutritional parameters in rainbow trout under the experiment conditions, although further research is suggested.

The present study was done to evaluate the presence of antibiotic resistance genes in Lactococcus garvieae isolated from cultured rainbow trout, West Iran.The isolates were examined for antimicrobial resistance using disc diffusion method. Of the 24 strains tested, 21 were resistant to ampicillin (87.5%), 9 to erythromycin (37.5%) and 19 to tetracycline (79.1%). Fourteen strains were resistant to four antibiotics, 8 resistant to five antibiotics and 2 to six antibiotics.The strains were also characterized for their genotypic resistance profiles. The results revealed that all 24 isolates contained one to three of the antibiotic resistance genes. StrA, tetS and ermB genes coding for streptomycin, tetracycline and erythromycin resistance were found in 7, 10 and 9 isolates, respectively and sulfamethoxazole resistance gene, sul2, was not detected in the examined isolates. High levels of antibiotic resistance and detection of resistance genes in L. garvieae strains should be considered as a potential danger for trout culture as well as for public health.

The silver crucian carp (Carassius auratus gibelio), a gynogenetic teleost, is a promising model for the study of evolutionary genetics in vertebrates. We identified ten gynogenetic clones (FZ-I~FZ-X) from triploid silver crucian carp, collected from Fangzheng County in Heilongjiang Province, China, using microsatellite markers. The genetic diversity of these gynogenetic clones was analyzed using 52 microsatellite markers. A total of 413 alleles were detected and the length of fragments ranged from 96 to 340 bp. The number of alleles per locus varied from 2~19 (mean=7.9423). The observed heterozygosity at polymorphic loci ranged from 0.10~1.00 (mean=0.80). The average allele count per gynogenetic clone ranged from 1.9423~2.1923. The ratio of the polymorphic locus was from 71.15% (VII) to 84.61% (IX) per clone. The number of genotypes ranged from 2~10 per locus. Ten genotypes were observed by analyzing each of 14 microsatellites. As a result, each gynogenetic clone could be accurately identified. In addition, the growth traits, including body weight, length, and height, among five gynogenetic clones were compared. There was a significant difference among gynogenetic clones. Clone FZ-V exhibited the best growth traits, with the largest body weight (53.17±5.24 g), length (11.38±0.37 cm) and height (4.69±0.18 cm). Our results provide basic data for the identification of silver crucian carp gynogenetic clones and can be used as a guide genetic breeding programs.

The chromosomal spread and karyotype of Anjak (Schizocypris altidorsalis) from Hamoun Lake were determined using tissue squashing techniques with an injection of 1 mL/100 g body weight of 0.01% colchicines solution. Kidney and gill epithelia tissues were removed and used for karyotype analysis. The analysis of 145 chromosome spreads revealed the diploid chromosome number of this fish, 2n=48 and a fundamental arm number (FN) =88. The diploid complements comprised 12 metacentric pairs, 8 submetacentric pairs, 1 subtelocentric pair and 3 telocentric pairs (12m+8Sm+1St+3t). Total length of the haploid complement equaled 44µm with a range in the length of the shortest and longest chromosome between 0.76-2.78µm. The arm ratio and the centromeric index ranged between l.00- and 0-50 respectively. This is the first report on the chromosome number and karyotype of S. altidorsalis from the Hamoun Lake in Iran.

Mitochondrial Cytochrome Oxidase Subunit I DNA sequences are a good discriminative marker for phylogenetic studies in crustaceans and especially in amphipoda. In the present study, molecular and morphological data were analyzed to test whether Gammarus lobifer authority and Gammarus balutchi authority which one or two geographically separated but morphologically similar species. The analyses proved that there are two species and that uplift of the Zagros Mountains was probably the most important cause of Allopatric speciation in this region during the Miocene period.

In the present study bacteriophages isolated from rainbow trout farms and sewage treatment plants were genetically identified and their effectiveness on Yersinia ruckeri isolates from clinical cases of red mouth disease was investigated. Fish samples suspected to red mouth disease were collected from rainbow trout farms located in west Azerbaijan. Y. ruckeri, the causative agent of red mouth disease was initially identified using biochemical tests. The biotypes of all Y. ruckeri isolates were determined and their identity was confirmed by employing genus specific primers. Antimicrobial resistance of Y. ruckeri isolates were examined using common antibiotics in use in aquaculture. In order to isolating lytic bacteriophages, environmental samples mainly from rainbow trout farms and sewage treatment plants were collected in a period of six months. Isolated bacteriophages were titrated using two-layer agar method and their bactericidal effects were examined. For molecular characterization of bacteriophages, genomic DNA was extracted. Extracted genomic DNA from bacteriophages was digested using Msp < /em>I endonuclease. The results revealed that 4.48% of examined fish were positive for Y. ruckeri. Bacteriophages isolated from urban sewage treatment plants were effective on Y. ruckeri isolates. Maragheh and Urmia sewage treatment plants had the maximum and minimum phage titers, respectively. The genomic DNA of all isolated phages were smaller than genomic DNA of Lambda phage and all examined phages showed similar genomic DNA digestion patterns. It was concluded that sewage treatment plants could be an important source for phages effective on Y. ruckeri and maybe other aquaculture bacterial pathogens.

The shelf-life of conventional surimi and isolated proteins that modified by acidic pH (2.5) and by using alkali pH (11) from silver carp (Hypophthalmichthys molitrix) was studied during months of storage at -18±2 °C. For conventional surimi, three washing steps were used. In the third stage of washing, 0.2% NaCl was used to withdraw more water. The result showed that isolated protein by alkaline pH has a higher efficiency. In the obtained result of percent yield and the recovery of protein product, isolated proteins showed higher values than conventional surimi. Isolated protein by using acid-aided processes had lower lightness and whiteness score, compared with alkaline-aided process and surimi prepared by a conventional washing method during frozen storage. The concentration of myosin heavy chain and actin were varied with solubilizing pH. Also, the lowest downfall of protein and the best surimi quality were found in produced samples with alkaline-acid aided process.

White spot syndrome virus (WSSV) is the causative agent responsible for huge-shrimp viral epidemics in shrimp farms throughout the world. Our study was aimed to determine the effect of WSSV Gamma-vaccinated Litopenaeus vannamei on the occurrence of apoptosis. One thousand and twenty PL15 were randomly distributed among 2 treatments and two control groups. Gama-Vaccinated shrimp and non-Gamma-vaccinated ones were our treated and untreated groups. Based on our results significant differences (p < /em><0.05) were observed in survival percent between vaccinated-exposed group (82.33±2.51) and non-vaccinated exposed group (26.00±10.00). It is concluded that apoptosis can be a helpful process in enhancing the immune response in shrimp especially against WSSV.

Chemical changes and shelf-life of common carp (Cyprinus carpio) surimi prepared by conventional washing method and solubilization by acid and alkali processes were investigated during 5 months of storage at -18 °C. Results showed that surimi produced with acid and alkaline solubilization is significantly higher yield than the conventional surimi. Protein solubilization by using acid and alkaline process was high compared with conventional method during storage in freezer except in the first month. Gel electrophoresis patterns showed a significant difference in hydrolyzing of myosin and actin proteins that was observed with increasing storage time. Surimi samples prepared by conventional method indicated more hydrolization, especially in the light chain of myosin during frozen storage. Evaluating the color characteristics (L*, a*, b*) of surimi samples showed that protein produced by using of pH 11 has the highest lightness after conventional surimi. Also, more whiteness in surimi prepared by conventional method was due to effective removal of myoglobin during washing. At zero month, total fat in the surimi samples prepared with acid and alkaline process was low than the surimi samples prepared by conventional method that it can intent to shelf-life increase and health of the product during storage.

Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that can be used for the management of fish industries in Iran. Mitochondrial DNA sequences were used to reconstruct the phylogeny of the Penaeus species of marine shrimp. For this purpose, DNA was extracted using phenol- chloroform well as CTAB method. The evolutionary relationships among 5 species of the shrimp genus Penaeus were examined using 610 bp of mitochondrial (mt) DNA from the cytochrome oxidase subunit I gene. Finally the cladograms were compared and the resulting phylogenetic trees confirmed that the Iranian species originated from the Indo-west pacific species. The Iranian species, which were not grouped with the other Penaeid taxa, seem to always form a sister- clade to the Indo-west pacific species with strong bootstrap support of 100%. Although the Iranian species + Western Hemisphere clade is paraphyletic in our gene tree, the bootstrap support is high. However, we still lack any comprehensive and clear understanding of phylogenetic relationships in this group.

Four hundred and eighty five rainbow trout (76 ± 6.44 g mean weight) were acclimated to laboratory conditions and then randomly divided into four groups of tanks in triplicate. The first group (Group 1) was fed on a commercial diet (control) without Bacillus subtilis supplementation. The second, third and fourth groups (Group 2, Group 3 and Group 4, respectively) were given a diet supplemented with 1, 5 and 10 g probiotic powder (containing 8×107 CFU g-1Bacillus subtilis) per kg commercial feed. Growth performance, immune responses and glucose levels were analyzed on days 0, 22 and 44. The results showed that dietary Bacillus subtilis supplementation significantly (p < /em><0.05) reduced final weight in treated groups compared with that in the control group. No significant difference (p < /em>> 0.05) was observed in weight gain rate (WGR) between the control and group 2. On the effect of dietary Bacillus subtilis on serum lysozyme, it was observed that group 3 and group 4 did not show any significant differences in serum lysozyme activity and serum total antibody on day 44. Results of alternative complement activity, showed significant increase during the experimental days (p < /em>< 0.05). Results on glucose assay showed that group 3 had the lowest glucose level (13.71 mg/dL) which was not significantly different than that in other groups on day 44. Fish diet supplementation with 5 g probiotic powder (Group 3) is preferable for immune system responses; however, high dose of Bacillus subtilis may be helpful to improve growth performance in rainbow trout,Oncorhynchus mykiss (Walbaum, 1792).

Measurement of chlorophyll-a can be considered important to investigate the primary production of an ecosystem. This study aimed to investigate chlorophyll-a concentration, primary production and the factors affecting them in Shadegan Wetland located in Khouzestan Province - Iran. Sampling for measuring (NO3, PO4, BOD5, DO, pH, EC, salinity, temperature) was performed seasonally at five sampling stations of the wetland (Canal, Ragbeh, Khoroosi, Mahshahr and Atish), from March 2013 – through February 2014. Results showed that chlorophyll-a concentrations in Canal station were significantly higher than that in the other stations; however, there were no significant differences among the other sampling stations (p < /em>>0.05). The maximum and minimum primary production (and chlorophyll-a) (62, 1.14 mg/m3) were observed at Canal and Ragbeh stations, respectively. Annual average chlorophyll-a concentration was 10.28 mg/m3, and there was no significant seasonal difference (p < /em>>0.05). The maximum value of chlorophyll-a was observed in the fall (29.63 mg/m3), whereas, the minimum value was related to the spring (4.07 mg/m3). Among the water physicochemical parameters, nitrate had a significant effect on chlorophyll-a concentrations. According to trophic state index (TSI), Shadegan Wetland is mesotrophic in the spring and winter, whereas it is eutrophic in the summer and fall. Overall, the lake is suitable for warm water species.

In the present investigation, co-invasion of Lernaea parasite is reported in some fish species, collected from the Kor River Basin (Dorudzan Reservoir and Kor River), Southwest of Iran in 2010 and 2011. Lernaea cyprinacea parasites were isolated from the external surface of eye, lips, gills, nostrils, fins, operculum and body of Alburnus mossulensis, Capoeta aculeata, Capoeta saadii (all native cyprinids), Cyprinus carpio and Carassius auratus (exotic cyprinids). The highest infestation was found in endemic fish, C. aculeata with 61ectoparasites in a single specimen of 348 mm TL. The greatest prevalence was found in C. auratus (100%) followed by C. saadii (80%), C. aculeata (69.4%), C. carpio (30.1%) and A. mossulensis (27.3%). Lernaea parasites may have been translocated into Dorudzan Dam by exotic species (e.g., C. carpio and C. auratus) through the four processes of introduction (transport in alien host and acting as co-introduced species), establishment (survival and reproduction in alien host, acting as co-introduced species), spreading with its original host (dispersal) and switching to a native host species to become a co-invader.

This study was carried out with the aim of detecting the dietary effects of isoflavone-genistein on hematological and immunological parameters in beluga, Huso huso in a 12-week feeding period. Five isonitrogenous (45% crude protein) and isoenergetic (19.5 MJ kg -1) diets were formulated to contain four graded levels of isoflavone-genistein, namely 0, 0.2, 0.4, 0.8 and 1.6 g kg-1 diet. Fish (initial average weight: 26.1 ± 1.8 kg) were stocked in ponds in groups of 3 and fed the experimental diets in triplicate. At the end of experiment, physiological indicators, including hematological and immunological parameters, such as red blood cell (RBC), white blood cell count (WBC), hematocrit (Ht), hemoglobin (Hb), lymphocyte, neutrophil, eosinophil, monocyte, haematological indices, lysozyme, total immunoglobulin (IgM) and complementary activities were determined. Results suggested that mean corpuscular hemoglobin concentration (MCHC) and values of neutrophil had significant differences between treatments. The activities of serum lysozyme, IgM, C3 and C4 were significantly influenced by the dietary genistein concentrations. Results indicated that genistein had significant effects on some hematological and immunological parameters in beluga.

Yersinia enterocolitica as a cause of septicemia in crucian carp (Carassius carassius)
L. Wang
qinxin916@aliyun.com

Yersinia enterocolitica is an important pathogen to animals and humans. Thirteen strains of Y. enterocolitica were isolated from diseased fish. The partial 16SrDNA gene, five virulence genes, pathogenicity, and drug resistance of Y. enterocolitica strain G6029 were studied using molecular biological technology and toxicological method. Results showed that the length of amplified 16SrDNA sequence was 1448bp, and revealed 99% homology with Y. enterocolitica. Its GenBank accession number was JX855135. Five virulence genes (ail, ystB, yadA, virF and HPIint) were detected, and only yadA gene was not seen. Twenty-eight crucian carps that were injected with strain G6029 died within a week, and the mortality was 93.3%, indicating highly pathogenic attribute of this strain. In addition, the strain G6029 was resistant to four antibiotics (sulfafurazole, furazolidone, enrofloxacin and norfloxacin), but it was susceptible to six antibiotics (florfenicol, vibramycin, cefaloridine, ciprofloxacin, streptomycin, and ampicillin). Further study of pathogenicity of Y. enterocolitica in teleost fish is suggested.

Zearalenone (ZEA) as mycoestrogen is found in human foods and animal feeds. Its estrogenic potency depends on its biotransformation fate. The hepatic biotransformation of ZEA in two species of sturgeon fish (Acipenser persicus and Huso huso) was investigated. ZEA was incubated with the hepatic microsomal and post-mitochondrial sub-fractions in the presence of NADPH and the metabolites were determined by means of HPLC. Moreover, the rate of glucuronidation for ZEA and its metabolites were estimated in the presence of uridine diphosphateglucuronic acid. b-zearalenol (b-ZOL) was found to be the major metabolite of ZEA by both sub-fractions. Enzymatic kinetics studies revealed that the maximum velocity (Vmax) in microsomal and post-mitochondrial fractions for b-ZOL production was found 5- and 7-folds in Huso huso and 8- and 12-folds in A. persicus higher than that for a-ZOL production, respectively. The H. huso hepatic post-mitochondrial fraction mainly glucurinated ZEA while in A. persicus, the metabolites and in particular b-ZOL were glucuronidated. Data suggest that the hepatic biotransformation of ZEA in studied sturgeons resulted in detoxification of ZEA as the main metabolite tends to be b-ZOL with weaker estrogenic property. Moreover, clear differences in glucuronidation profile are indicating interspecies variety in hepatic biotransformation of ZEA.

This study aims to investigate the relationship between the development of pharyngeal taste buds (TBs) and first feeding of Hucho taimen. Larvae were fed with live food (water flea and tubifex) for 8 weeks. TBs of larval pharynx were histologically examined using light microscopy during the rearing experiment. The results showed that the first few TBs primordia were visible within the pharynx 27 days after hatch (DAH), which coincides with the onset of feeding, and the first few TBs with open receptor areas appear 45 DAH. TBs of pharynx were well developed 76 DAH. The number and size of TBs were quantified during larval development. The average number of pharynx was 8.63±1.15, 11.29±0.50, 14.50±1.06, and 17.78±0.47 TBs at 27, 36, 45, and 76 DAH, respectively. The number of TBs increased in both the upper and lower pharynx. The ratio of height to width of TBs showed an increase tendency, ranging from 0.81 to 1.11. The height of TBs showed an increase tendency after 29 DAH during the development. However, the width of TBs exhibited a low at 35 DAH. In conclusion, the development of pharyngeal TBs coincides with the first feeding, and this should lead to a better understanding of improvement of larval rearing in H. taimen hatcheries.

Utilization of genistein as a natural inhibitor was studied alone and in combination with conventional treatments on melanosis and microbial quality of fresh L. vannamei during 10 days ice storage. Treatments were as followed: A (dipping samples in distilled water), B (dipping in 1.25 % sodium metabisulphite solution), C (dipping in 0.01 % genistein + 2% glycerol solution), D (dipping in 0.1 % genistein + 2% glycerol solution), E (dipping in 1% NaCl + 0.05 % EDTA + 0.5 % ascorbic acid + 0.5 % lactic acid solution), F (dipping in 0.01% genistein + 2 % glycerol + 1 % NaCl + 0.05 % EDTA + 0.5 % ascorbic acid + 0.5 % lactic acid solution) and G (dipping in 0.1 % genistein + 2 % glycerol + 1 % NaCl + 0.05 % EDTA + 0.5 % ascorbic acid + 0.5 % lactic acid solution). Results showed that G treatment was more affective on inhibiting of melanosis in L. vannamei. Mesophilic and psycrophilic bacterial counts in G treatment were lower than other treatments during ice storage.

Different kinds of freezing-point regulators were evaluated to expand the freezing point zone of large yellow croaker, and several treatment methods such as ordinary atmospheric pressure, vacuum environment and injection during the process of penetration were compared to reveal the relationship of diffusion velocities, diffusion time and freezing point of the large yellow croaker. Results obtained for ideal freezing-point regulators were as follows: Sodium chloride 2.5% (w/w), trehalose 2.5% (w/w) and edible alcohol 2.0% (w/w), which could decrease the freezing point from -1.5℃ to -4.2℃. Comparing with atmospheric pressure or vacuum degrees treatment, using injection method to deal with the freezing-point regulators could decrease the freezing point in a short time and benefit the meat quality.

Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO2/75% N2 (M4) and 100% N2 (control). High CO2 concentration (M1 and M2) of fish fillets delayed the psychrophilic bacteria growth compared to low CO2 concentration (50% and 25% CO2) as well as the mesophilic, anaerobic and histamine forming bacteria. We concluded that the atmosphere with 75:25% and 100:0 (CO2:N2) had the most appropriate gas composition to inhibit the microbial growth and prolong the shelf life of barramundi fillets (p<0.05).

To our knowledge, no previous anaesthetic experiments are conducted on shabbout fish. The results from the present study indicated that the induction times decreased significantly as the doses increased in all the anaesthetics (p < /em><0.05). Induction and recovery times were significantly affected by the interaction between concentration and anaesthetic (p < /em><0.05). The effective doses were: 25 and 50 µL L-1 at 24°C clove oil and for eugenol, 50 mg L-1 for benzocaine and 500 µL L-1 for 2-phenoxyethanol. In conclusion, the four anaesthetic agents could be used as sedatives in culture of shabbout fish

The transcriptome of triangle sail mussel Hyriopsis cumingii (Lea) using Illumina paired-end sequencing technology was conducted and analyzed. Equal quantities of total RNA isolated from six tissues, including gonads, hepatopancreas, foot, mantel, gills and adductor muscles, were pooled to construct a cDNA library. A total of 58.09 million clean reads with 98.48 % Q20 bases were generated. Clustering and assembly of these reads produced a non-redundant set of 92,347 unigenes with an average length of 1,150.61 bp. 11,174 unigenes were involved in the molecular function, cellular component and biological process categories by GO (Gene Ontology) analysis. Potential genes and their functions were predicted by KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway mapping and COG (Cluster of Orthologous Groups of proteins) analysis. More than 8 putative genes of interest involved in sex determination/differentiation were identified. Furthermore, 8,014 SSRs and 38,288 SNPs were identified in this transcriptome dataset.

The aim of this study was to compare some biochemical blood parameters of rainbow trout (Oncorhynchus mykiss) living in running or still waters. Some biochemical parameters of rainbow trout were examined, and the results were evaluated between sampling locations and according to seasonal changes. Healthy adult rainbow trout were caught from six different locations on the Bahçelik Dam Lake and the Zamantı River (Turkey). Blood samples were collected from the caudal vena cava and transferred to sample tubes. The blood serum samples were analyzed for 16 different biochemical parameters. In terms of the calculated blood parameters, no statistically significant differences were found between locations. However, seasonal changes affected the blood parameters significantly. alanine transaminase (ALT)was considerably higher in spring in fish caught from both the dam lake and the river. In the summer, aspartate transaminase (AST), Ca, urea, total protein and Fe were significantly higher than in other seasons. However, amylase was significantly lower in summer than in the other seasons. In the autumn, alkaline phosphatase (ALP) and triglyceride were significantly higher than in the other seasons. The results obtained from this study may be useful for research in fish biology and food safety

The Choghakhor International Wetland plays an important role in preserving and protection of part of the plant and animal species in the Iranian plateau. Since the water of this wetland is utilized for different human purposes, complete periodic chemical and physical quality assessment of its water seems necessary. Water quality index (WQI) was calculated using the following eleven parameters: Nitrate, Nitrite, Ammonium, Alkalinity, Hardness, Turbidity, Conductivity, Dissolved Oxygen, Total Dissolved Solid, pH and Biochemical Oxygen Demand (BOD5). For this purpose, the relative weight assigned to each parameter ranged from 1 to 4 based on the importance of the parameter for aquatic environment and human health. The analyses of variance (ANOVA) of data revealed significant differences between different periods of sampling (p < /em><0.01). Therefore we assigned the results in two categories: very poor and inappropriate, which make it not suitable for human uses such as drinking. The most important factor in assessment of water quality in this study was BOD5. The result of this research demonstrated that this method can be used for assessment of water quality in wetlands.

To understand the acclimation strategies of red tilapia to different environments, this study aimed to evaluate different responses of red tilapia (O. mossambicus × O. niloticus) to salinity (10-30‰), alkalinity (1-3 gL-1 NaHCO3) and salinity and alkalinity (10/1-30/3 ‰/gL-1NaHCO3) environments. Localization, type, size, and numeration of gill ionocytes were investigated on the same specimens by scanning electron microscopy (SEM) and immunohistochemistry (IHC) with antibodies of Na+/K+-ATPase (NKA), Na+/K+/2Cl-contransporter (NKCC), cystic fibrosis transmembrane conductance regulator (CFTR) and carbonic anhydrase (CA). Ionocytes were only located on filaments conducted by SEM. Four types of ionocytes namely pit, convex, concave and transitory types were determined morphologically by their apical openings of which concave and transitory type were not present in freshwater (FW) and saltwater (SW) fish (10). Both ionocytes size and number increased with elevated stress levels. In comparison to FW, density of ionotypes increased to about 4.75, 3.00 and 3.44 fold in SW (30), AW (3) and S&AW (30/3) respectively. Immunoreactive cells on gill filaments confirmed branchial distribution of ionocytes. Immunoreaction of NKA, NKCC and CA appeared in FW except for CFTR while they all appeared in SW (30), AW (3) and S&AW (30/3).
