Prediction of survival rate in European white fish (Coregonus lavaretus) fry on three different feeding regimes
During the early stages of white fish, survival rate is a very effective parameter on future fry’s sustainability, especially when they are going to be released into the natural habitat for restocking. The aim of this study is to define relationships between morphological and functional traits and the survival rate of the European white fish fry (Coregonus lavaretus) when they were fed with different feeding regimes. One hundred and fifty newly hatched white fish fry stocked into nine rearing cages, under a flow-through rearing system, were distributed randomly in a natural pond, and nourished for twelve weeks with three kinds of food, the rotifer (Brachionus plicatilis), a compound Salmonidae commercial diet and a mixture of 50% of each , all treated in triplicates. The backward method of regression procedure was used for statistical analysis. Combinations of independent variables to multiple linear regression models were based on the changes in the R2 statistics and the F-value were produced by adding or deleting an independent variable. The five variable combinations (individual weight, length, total weight gain, total feeding rate, and feed efficiency) predicted the larval survival rate in multiple linear regression models and supported by partial correlation. This study revealed that length and weight bear negative signs whenever they appear in these statistical relations. Also the higher the feeding rate, the survival rate increases accordingly regardless of the treatment effect. Finally, in mixed feed, predicting the survival rate is easier and more practical since the only parameters remaining in the equation are the length and weight of the fry. Perhaps this finding is because of the fact that the co feeding (rotifer and compound) can better satisfy the nutritional needs of these larvae than each feed alone.

Evaluation of selected substrates for collection of hatchery reared black-lip pearl oyster (Pinctada margaritifera) spat
An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number of dead spat after settlement on pipe (1.4%) and basket (1.5%) were not significantly different (P > 0.05). Possible factors causing the pattern of settlement reveals that it could be related to the material used in collector, reaction to light and gravity force. These results indicated that polyethylene pipes positioned horizontally in the third bottom part of the tank are suitable for the settlement of P. margaritifera pediveliger larvae in a hatchery and may also be suitable for grow out in the ocean.

Comparative effects of pure spirulina powder and other diets on larval growth and survival of green tiger shrimp, Peneaus semisulcatus
This experiment was carried out in Bandargah Station in Bushehr province. Peneaus semisulcatus larvae were fed on Spirulina platensis as supplementation microalgae. In order to use spirulina platensis in this study, we have to produce biomass and dry production of this microalga. Determination of length and survival rate of Peneaus semisulcatus larvae was carried out as the objective of the study. Treatments including Z plus (as a supplementation without spirulina), M.C.F (as an imported enriched spirulina), the powder combination of Spirulina platensis with Z plus and Spirulina platensis as live food were compared to Cheatocerus microalgae as a control. The experiment was carried out from nauplii stage to early post larvae. The results of the experiment indicated that the powder combination of Spirulina platensis with Z plus treatment has the most survival rate (76.5%). The maximum of length (4.3mm) observed in control (Cheatocerus spp.).The maximum mortality was observed in zoa stage in spirulina microalgae treatment, because the spiral filamentous of spirulina sp.was large.

Production of Fish Chips from Sand Smelt (Atherina boyeri, RISSO 1810) and Determination of Some Quality Changes
In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18 o C for 6 months) were determined. The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying process resulted in a decrease in all fatty acid compositions except for C18:1 w-9 and C18:2 w-6.Difference between the pH and thiobarbituric acid (TBA, µg malonaldehyde/g) values of raw fish meat and pre-fried chips was insignificant (P>0.05). However, total volatile basic nitrogen (TVB-N, mg/100g) value was changed significantly (P<0.05) between raw fish meat and pre-fried chips. The results of sensory analyses made by panelists were as follows fish chips enjoyed it very much. The results of chemical, sensory and microbiological analyses of fish chips performed following frozen storage period at -18 oC for 6 months were within the acceptable limits.

Population structure, growth and reproduction of leaping grey mullet (Liza saliens Risso, 1810) in Beymelek Lagoon, Turkey
Population structure, growth, length-weight relationship and reproduction characteristics of leaping grey mullet (Liza saliens (Risso, 1810) were investigated in Beymelek Lagoon from February 2006 to January 2007. During the study, a total of 1248 leaping grey mullet were captured by gill- and trammel nets of various mesh sizes. Male to female ratio for leaping grey mullet population in Beymelek Lagoon was 1:2.71. The ages ranged from 1 to 4 years for males and from 0 to 5 years for females. The growth parameters of the von Bertalanffy equation were: L∞ = 35.2 cm, K = 0.276 year-1 and t0 = -2.893 year for males, L∞ = 35.9 cm, K = 0.386 year-1 and t0 = -1.760 year for females and L∞ = 39.9 cm, K = 0.271 year-1 and t0 = -2.233 year for all individuals. The calculated length-weight equations were W = 0.0061*L3.124 for males, W = 0.0060*L3.124 for females and W = 0.0099* L2.954 for all individuals. The slope (b) values of the length-weight relationship showed that weight of leaping grey mullet in Beymelek Lagoon increased with length in isometric. The mean condition factor for males, females and all specimens were determined as 0.908, 0.900 and 0.897, respectively. According to sex groups, the mean condition factor of males was slightly higher than that of females. The total length at 50% maturity for female leaping grey mullet was determined as 23.3 cm. It was assumed that spawning period for this species was from May to July.

Some biological aspects of Gammarus lacustris Sars, 1863 in Neur Lake Ardabeel province, Iran
A biological study was conducted to find out about reproduction and feeding of G. lacustris in Neur Lake from northwest mountains of Iran. Plankton diversity, hydro-chemical factors and substrate characteristic were recorded monthly. Findings showed that reproduction period of this species was short and limited to May and the mean brood size was 10.2 ± 5.3 eggs per female. The hydro-chemical analysis showed the eutrophic characteristic of Neur Lake in which the average of total organic matter was 3.7 ± 3.0 percent. The phyla representative Bacillariophyta, Chlorophyta and Cyanophyta were observed throughout the study and Chlorophyta was the dominant group. Three zooplankton phyla Rotatoria, Ciliophora and Copepoda were abundant respectively. Study on diet using gut content resulted in identification of 15 plankton genera with some resemblance to planktons of the lake.

Immunological and histopathological changes in Penaeus semisulcatus challenged with Vibrio harveyi
Two-hundred and sixty five green tiger shrimp juveniles (Penaeus semisulcatus) with the average weight of 7-12g were collected from Helleh farms in Bushehr province and transported to Iran Shrimp Research Center of Bushehr in October, 2009. The juveniles were acclimated for two weeks. The experiment was designed in three treatments (named 3, 4 and 5) and two controls (named 1 and 2) in triplicate with 15 shrimp in each repetition prepared of glass aquarium. All the treatments and repetitions were exposed to Vibrio harveyi (NCBI: GU974342.1). The concentrations of the treatments were 108,106 and 104 CFU ml-1 in individual containers dedicated for each mentioned treatment (3, 4 and 5, respectively). The controls prepared with no any bacteria and fully filled with chlorinated and UV treated sea water were named 1 and 2 respectively. The hemolymph were withdrawn from abdominal segments of samples for measuring THC and TPC evaluation at designed hours (2, 6, 12, 24, 48, 96, 144, 192 and 240). The shrimp samples were also fixed in Davidson fixative for histopathological studies. The results showed that the difference of THC value between controls and group 3 during 12 till 96 hours of experiment was significant (P< 0.05). The differences between groups 4 and control of THC value during 24 to 144 hours of experiment were also significant (P< 0.05). There was no significant difference (P> 0.05) between group 5 and control groups of THC. The data showed that differences of TPC value between control groups during 24 to 96 hours were significant (P< 0.05), whereas the differences between controls with groups 4 and 5 during 48 to 144 hours and 192 hours, were significant (P< 0.05) respectively. TPC and THC were observed with an increase in the concentration of bacteria and passing the time as inverse bell shape procedure. In histopathology, gills showed melanization and color changed to brown and black. The hepatopancreas cells revealed necrosis and vacuolization of B, E, R and F cells. The bolitas ball and bacterial colonization was observed in the intestine. Our results showed that Vibrio harveyi with 108 and 106 cell/ml decreased immunity factors such as THC and TPC. The histopathological changes increased with increasing the concentration of bacterial level. This finding can be used for assessing the health of shrimp culture and prevention of vibriosis.

Survey on fungal, parasites and epibionts infestation on the Astacus leptodactylus (Eschscholtz, 1823), in Aras Reservoir West Azarbaijan, Iran
A total of 394 (255 males,139 females) live freshwater crayfish Astacus leptodactylus from four stations of Aras reservoir in West Azarbaijan Province (North-Western Iran) were studied during the winter until early autumn of 2009 for the presence of parasites, Epibionts and Fungal agents. Parasitological surveys were carried out on gills exoskeleton and internal organs, mycological examinations on the exoskeleton (the legs, abdominal cuticle and the eggs). 9 epibionts and parasites peritrich protozoans including :Cothurnia sieboldii (68.5%), Zoothamnium spp. (56.6%), Vorticella similis (45.6%), Chilodonella spp. (0.5%), Podophrya fixa (7.8%), Epistylis chrysemidis (53.2%), Pyxicola annulata (66%), Opercularia articulata (19.8%), Tetrahymena pyriformis (0.5%) were recorded. From Metazoan parasites group, Branchiobdella kozarovi (71%) as the first observation was the only parasite recorded from exoskeleton with prevalence (100%) during spring and summer of the study year. Infected gills were heavily damaged with Aeolosoma hemprichi (Annelid) in winter with 90% prevalence. Other Epibiont fouling organisms such as Rotatoria free living Nematods were observed in this survey. Furthermore, on the mycotic agents identified Penicillium expansum Aspergillus flavus Alternaria sp. Fusarium sp. and Saprolegnia sp. were isolated in IM media and identified with slides cultured from cuticular melanized lesions and eggs of infected specimens. This is the first investigation on epibionts, parasites and fungal organisms of the endemic crayfish in Aras reservoir, Iran.

Effect of Gamma Irradiation on Fatty Acid Composition of Rainbow Trout (Oncorhynchus mykiss) Fillets
The present study was conducted to evaluate the effect of low-dose gamma irradiation (0, 1, 3 and 5 kGy) on fatty acid composition of Rainbow trout (Oncorhynchus mykiss) fillet. Among all of the fatty acids, oleic acid (C18:1) (with mean 33.50±3.02 g/100 g fatty acids) and myristoleic acid (C14:1) (with mean 0.41±0.26 g/100 g fatty acids) were the most predominant and the lowest fatty acids in all irradiated and non-irradiated samples, respectively. Statistical analysis showed that there were no significant differences (P>0.05) in level of all fatty acids, saturated fatty acids (SFA), unsaturated fatty acids (USFA), mono unsaturated fatty acids (MUFA) and poly unsaturated fatty acids (PUFA) between Rainbow trout fillet control and irradiated in 1, 3 and 5 kGy. Therefore irradiation process and different doses of irradiation in this study (1, 3 and 5 kGy) had no significant effect (P>0.05) on fatty acid composition.

Hormonal sex reversal of rainbow trout (Oncorhynchus mykiss) by ethynylestradiol-17α (EE2)
Rainbow trout (Oncorhynchus mykiss) females grow larger and mature later than males, making all-female stocks economically advantageous. The objective of this research was to develop methods for the production of monosex populations of trout through the use of sex steroids. The synthetic estrogen ethynylestradiol-17α (EE2) was administered in single period-immersion treatment of 400 µg/l for 1, 2, 4 and 8 h to groups of newly-hatched sac fries of rainbow trout and in a 30 day dietary treatment of 5, 10, 15 and 20 mg/kgf of newly swum up fries. 73.4 And 94.5% females were obtained with 1 and 2-h single-immersion of EE2 respectively (38% female in control). However, higher doses progressively reduced the survival drastically. Sex ratios of dietary treatment of fry were 60, 57.4, 78 and 94% females respectively. Treatments also resulted in a slight increase of both weight and length. This increase was related to the method of hormonal exposure (dietary<shape style="WIDTH: 13.5pt HEIGHT: 18.75pt" id="_x0000_i1026" type="#_x0000_t75" equationxml="
12 >"> immersion), but not dosage-dependent for utilized hormone. This demonstrates that the direct feminization of rainbow trout can be achieved and resulted in sex reversal ratio effectively but not decreased the growth, as observed in hormonal sex reversed females, and it would be a noticeable approach to the direct feminization of trout.

Effects of Zataria multiflora and Eucalyptus globolus essential oils on haematological parameters and respiratory burst activity in Cyprinus carpio
The present study was undertaken to investigate the effects of Zataria multiflora and Eucalyptus globolus essential oils on some haematological parameters and respiratory burst activity in common carp (Cyprinus carpio). 260 fish (30±5g) were randomly distributed in 13 treatment groups each one in three replicates and different doses of essential oils in 16-17ºC were administrated. The fish were sampled on day 1, 2, 8, 15 and 22 after the 8-day trial. Haematological parameters (red blood cell count, haematocrit) and respiratory burst activity were then evaluated in all treatment groups. The results suggest that essential oils especially Zataria multiflora in dietary intake significantly enhanced respiratory burst activity of blood neutrophlis (P< 0.05). Meanwhile, essential oils had moderate effects on RBC and haematocrit. Significant increases in RBC and haematocrit levels were just noted in T11 treatment group (P< 0.05). This study indicates that dietary administration of Zataria multiflora and Eucalyptus globolus essential oils could be used to promote the health status of common carp during temperature stress.

Growth performance, carcass composition, and immunophysiological indices in juvenile great sturgeon (Huso huso) fed on commercial prebiotic, Immunoster
Growth performance, carcass composition, and immunophysiological indices in juvenile great sturgeon (Huso huso) fed on commercial prebiotic Immunoster (IS) were investigated. After a four-week acclimatization period, 270 great sturgeon juveniles weighing 95.68 ± 10.05 g were randomly distributed into 9 fiberglass tanks in three replicates and kept at a density of 30 fish per tank for a period of 8 weeks at water temperature 20.55 ± 5.11ºC and dissolved oxygen 6.73 ± 0.35 mg L-1. IS was added at two levels of 1% and 3% to the basal diet in place of cellulose. At the end of the trial, blood sampling and carcass analysis were conducted. Weight, length, body weight increase (BWI), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER) and condition factor (CF) were significantly affected by IS 3% compared with IS 1% and the control (P<0.05). There was significant difference (P<0.05) in crude protein of carcass between the experimental groups. Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) showed significantly higher levels in experimental treatments compared with the control (P<0.05). Immunoglobulin M (IgM) level and lysozyme activity in IS 1% group were higher than the control group. It can be concluded that IS can enhance growth performance and improve some immunophysiological indices of great sturgeon.

The impact of lipid content, cooking and reheating on volatile compounds found in Narrow – barred Spanish mackerel (Scomberomorous commerson)
Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectively. Total concentrations of volatile had increased from 72.80 to 111.06, 74.25, 112.19 and 92.37 μg/kg, respectively. The concentration and new flavor compounds were increased by chill-reheating, due to the fast oxidation. The concentration of alcohol and aldehydes increased significantly (P<0.05). The hexanal amount also increased in all samples and indicated a marked development of warmed-over flavor. Quantitative and qualitative (P<0.05) differences were observed in volatile compounds between raw and cooked samples.
