In addition, the impact of Trabzon-Yomra fish-farming activity on benthic communities was low. The degree of exposure for Rize fish-farming area in all seasons was quite low, which was not a significant negative impact.}, Keywords = {Cage culture, Benthic organisms, Ecological quality, Marine biotis indices, Black Sea, Turkey}, volume = {13}, Number = {3}, pages = {719-738}, publisher = {Iranian Fisheries Research Organization}, url = {http://jifro.ir/article-1-1729-en.html}, eprint = {http://jifro.ir/article-1-1729-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2014} } @article{ author = {Fallahi, M. and Rahbary, S.H. and Shamsaii, M.}, title = {Determination of optimum concentration of Diuron for the growth and bloom of the algae (Scenedesmus obliquus) in in Vitro condition}, abstract ={Growth rate of the green algae, Scenedesmus obliquus, influenced by Diuron, with the trade name of (Karmex) and chemical name of (N'-(3,4-Dichlorophenyl)-N,N-Dimethylurea), was examined in the present study. This study is performed in the laboratory of National Inland Waters Aquaculture Institute in Iran during 96 hours in 6 treatment and 3 replicates, using 500 cc Erlenmeyer Flasks. Measurement of growth rate in the same period of time was performed by three simultaneous methods of cell counting, measurement of turbidity and determination of the rate of chlorophyll a. Quantities of EC10, EC50, EC90 and allowable concentration level of this poison for the studied algae were obtained as 0/0019, 0/1, 0/05, 0/02 milligram per liter, respectively. Achieved quantities of EC were used in four 500cc Erlenmeyer flasks each containing more than one million algae cells and in 24h periods adding up to be 96 hours, concentration of the algal cells was evaluated by cell counting. Results of the present experiment showed that the frequency of S. obliquus was significantly different in presence of concentrations obtained from EC indicators and decreased sharply in EC90 quantities.}, Keywords = {Scenedesmus obliquus, Diuron, Growth rate, Chlorophylla}, volume = {13}, Number = {3}, pages = {739-747}, publisher = {Iranian Fisheries Research Organization}, url = {http://jifro.ir/article-1-1730-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2014} } @article{ author = {Shahmohammadi, H.

Response Surface Methodology (RSM) was used to study the effect of fish meat content and to optimize the feed composition. Fourteen treatments from central composite design considering minced fish content (0-3 kg) and corn (7-10 kg) were used as the independent variables. The expansion ratio, protein content, fish odour, and overall acceptability were the dependent variables. Fish odour, linear distance and protein content of puffed corn-fish snack increased significantly with fish content while the expansion ratio significantly decreased (p<0.05). The optimum formulation was obtained at 15% of minced fish.}, Keywords = {Minced fish, Silver carp, Expansion ratio protein content, Extrusion, Response Surface methodology}, volume = {13}, Number = {3}, pages = {748-760}, publisher = {Iranian Fisheries Research Organization}, url = {http://jifro.ir/article-1-1731-en.html}, eprint = {http://jifro.ir/article-1-1731-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2014} } @article{ author = {PeykaranMana, N. and Vahabzadeh, H. and Seidgar, M. and Hafezieh, M. and Pourali, H.

The presence of highly unsaturated fatty acids is a key factor that determines the nutritional value and marketing of Artemia for shrimp, marine larvae, sturgeon and ornamental fish industries. To determine the variation in nutritional content in cysts, decapsulated cysts and nauplii of Artemia from three different biotopes of Iran, were tested for their protein, lipid, energy, and fatty acid profiles, particularly essential fatty acids. The cysts collected from Urmia, Maharlou and Meighan lakes, were rinsed, processed, decapsulated, hatched and then analyzed for proximate and fatty acid composition using standard methods. Statistical comparisons of the results revealed significant differences not only in proximate composition but also in fatty acid contents (p<0.05). The highest mean (±SD) level of protein (60.5±3.3 %), lipid (18.60±1.1%) and energy contents (5448.3±10.4 Kcal/kg) were observed in Instar I nauplii hatched from Urmia Lake cysts, Instar I nauplii hatched from Maharlou Lake cyst and Instar I nauplii hatched from Urmia Lake decapsulated cyst, respectively. The highest content of DHA (0.78 mg/g DW) was observed in nauplii of cysts from Urmia Lake whereas, it was around zero in other samples. The highest level of EPA (24.24 mg/g DW) was measured in nauplii from Maharlou Lake decapsulated cysts and the lowest (0.24 mg/g DW) was observed in Urmia lake cysts. The results revealed that the nauplii from decapsulated cysts of Maharlou Lake Artemia contained significantly higher levels of EPA and n-3 HUFA compared to others. Therefore, it is recommended to use it in aquatic larviculture.}, Keywords = {Artemia, cyst, Decapsulated cyst, Nauplii, Nutritional value, Fatty Acid Profile}, volume = {13}, Number = {3}, pages = {761-775}, publisher = {Iranian Fisheries Research Organization}, url = {http://jifro.ir/article-1-1732-en.html}, eprint = {http://jifro.ir/article-1-1732-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2014} } @article{ author = {Khakshoor, M.

Gelliodes carnosa sponge was collected from Nay Band Bay (Persian Gulf waters) and antimicrobial activities of crude extracts were explored by calculation of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) in media supplement with different concentrations of extract solutions. Seven extracts of sponge with solvents of different polarity (E1: Ethanol, E2: Methanol, E3: Acetone, E4: Ethyl acetate, E5: Chloroform, E6: Mixed (Ethanol: Ethyl acetate: Methanol 1:2:1), E7: Distilled water) were evaluated through disc diffusion assay. Different extracts were inhibited the growth of bacteria (70%) more frequently compared to fungal strains (26%). Gram-negative bacteria were more sensitive (72%) to many extract compared to Gram-positive bacteria (65%). Considerable antibacterial activity was exhibited by E6 against Bacillus subtilis (MIC: 203 µg/ml), Klebsiella pneumonia (MIC: 203 µg/ml), Escherichia coli (MIC: 407 µg/ml) and Fusarium solani (MIC: 500 µg/ml). Strong antifungal activity was obtained by E4 against Fusarium sp.2, Fusarium sp.1, F. solani and Saprolegnia parasitica (MIC: 500µg/ml). This is the first report of antimicrobial and antifungal activities of G. carnosa extracts.}, Keywords = {Marine sponges, Gelliodes carnosa, Secondary metabolites, Persian Gulf, Iran}, volume = {13}, Number = {3}, pages = {776-784}, publisher = {Iranian Fisheries Research Organization}, url = {http://jifro.ir/article-1-1733-en.html}, eprint = {http://jifro.ir/article-1-1733-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2014} }
