The area was stratified for 10 transects and each transect was divided into three stations: Station 1 for waters below 10m, station 2 for waters between 10 and 20m and station 3 for waters between 20 and 30m deep. Habitats of fauna and flora including communities of corals, seaweeds, sea cucumbers and sea grasses and sedimentation depth through scuba diving were studied in each transect and sub-transects. Sea grass communities existed in some spots within station 1 in Bandar Mesan, Bandar Lengeh, Kish Island and Bandar Chirooyeh transects, while for station 2, sea grasses were absent from Chirooyeh transect and present in Bandar Mesan, Bandar Kong and Kish Island transects. Also, seaweed habitats existed in station 1 in Bandar Mesan transect and some areas in Bandar Lengeh transect. Study of coral and sea cucumber communities indicated existence of Acropora sp. habitats in Bahman jetty, Bandar Mesan and Bandar Bostaneh transects, Porites sp. habitat in Hengam Island transect, Holothuria sp. habitats in Bandar Mesan and Bandar Lengeh transects and Stichopus sp. habitat in Hengam Island transect. All of these habitats were located in station 1 and had patchy distribution which was drawn in GIS software. Calculated sedimentation depth using degree scale in different transects demonstrated statistically significant differences between station 1 in Bandar Salakh transect and the same stations in other transects, also between station 2 and station 3 in other transects (P<0.05). The result of sedimentation depth assessment showed that station 2 in Bandar Lengeh area up to Hendurabi Island were better for artificial reefs installation compared to south of Gheshm Island with the exception of Bandar Kong and Bandar Chirooyeh transects. *Corresponding author}, Keywords = {Artificial reef, GIS, Coral, Sea cucumber, Seaweed, Sea grass and Persian Gulf}, volume = {20}, Number = {2}, pages = {9-16}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.109987}, url = {http://isfj.ir/article-1-364-en.html}, eprint = {http://isfj.ir/article-1-364-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2011} } @article{ author = {Parvaneh, M. and Khaivar, N. and Nikpour, Y. and Nabavi, S.M.}, title = {Heavy metals (Hg,Cd,Pb,Ni,Cu) concentrations in Euryglossa orientalis and sediments from Khur-e-Musa Creek in Khuzestan Province}, abstract ={Heavy metals contamination (Hg,Cd,Pb,Ni,Cu) in muscle of the fish Euryglossa orientalis and in sediments was assessed in 2007 in Khur-e-Musa Creek (Ahmadi and Ghanam).

Na+,K+-ATPase localization was performed using IgG 5 antibody and immunohystoshimy technique. In order to count cells in gill area, immunofluorescence light microscopy pictures was analyzed using Image Tool 2.1 software. Chloride cells were found on gill arch, lamellae and filament. Filamentary chloride cells and their total number (chloride cells in lamellae and filament) had no significant difference in all 5, 15, 25g specimens but lamellar chloride cells in 5g fries was significantly decreased. Also, percentage of lamellae chloride cells in 15g specimens and those of filament chloride cells in 5g fries was higher than other weights. According to our results, weight has important impact on osmoregulation ability in same age fishes. Fries with higher weight can resist salinity stress after migration to Caspian Sea through production of more chloride cells and change in their position but those which remain in freshwater for a long time, would adapt easily to the new environment. *Corresponding author}, Keywords = {Osmoregulation, Salmo trutta caspius, Na+,K+-ATPase, IgG 5, Caspian Sea}, volume = {20}, Number = {2}, pages = {49-60}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.109991}, url = {http://isfj.ir/article-1-368-en.html}, eprint = {http://isfj.ir/article-1-368-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2011} } @article{ author = {Zahedi, S. and Mirvaghefi, A.R. and Rafiee, Gh.R. and MojaziAmiri, B. and Hedayati, M. and Makhdoomi, Ch. and ZareiDengasraki, M.}, title = {The effects of exposure to sub-lethal copper and cadmium concentrations on biochemical factors of one year old Persian sturgeon, Acipenser persicus}, abstract ={The aim of this study was to determine the 96h LC50 of copper and cadmium, and also, to evaluate the effects of their sub-lethal dose on stress factors in Persian sturgeon, Acipenser persicus.

One of the most important farm species is considered to be the Nile Tilapia (Oreochromis niloticus). The effects of different cooking methods on fatty acid composition and nutritional value of Tilapia fish fillet were evaluated. The cooking methods included: Red off, microwave, oven cooking, barbecue, boiled water and raw treatment. The protein content was assessed using the Kjeldahl method, moisture was evaluated through dry method, fat and ash through Soxhlet and electric furnace methods. To measure the composition of fatty acids, Gas-chromatography method (GC) was applied, and the Bligh and Dyer method of extraction and identification of fatty acids was implemented. The results showed that applying different curing methods caused moisture loss of 1-9%, 2-12% increase in protein content, fat reduction of 0.2-4.2% (excluding the red off treatment in which fat increased by about 0.5%), increase in ash of 0.7-0.15%, reduction of Mono Unsaturated Fatty Acids between 1-6% and increase in Poly Unsaturated Fatty Acids between 0.5-14%. The rate of saturated fatty acids showed an increase of 0.6-1.6% in all treatments with the exception of baking and red off treatments. The results indicated the lowest change (about 0.2%) in EPA, in the microwave and grilled fillet treatments and the highest change (0.7%) in the red off fillets compared to raw samples. The minimum change in DHA was observed in the oven-cooked fillets (0.45%) and the maximum change (2.5%) in the red off fillets.

We found 4 species of Thaliacea: Doliolum denticulatum, Doliolum nationalis, Thalia democratica, Salpa cylindrica. In addition, we observed a life stage of Doliolum. The highest frequency was observed in May and in the south station. There was significant correlation between abundance of Doliolum denticulatum and its late oozoid or old nurse and between Thalia democratica and Doliolum denticulatum. *Corresponding author}, Keywords = {Thaliacea, Tunicates, Holoplankton, Life cycle, Hormuz Island}, volume = {20}, Number = {2}, pages = {159-166}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.110001}, url = {http://isfj.ir/article-1-378-en.html}, eprint = {http://isfj.ir/article-1-378-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2011} }
