A 1800 km of northern coastline of the Persian Gulf, the Oman Sea and more than 14 islands belong to Iran have provided great possibilities of economic activities. In-shore marine islands such as Kish, Farour, Hendurabi, Tonb made a good opportunity for fishing and harvesting of ornamental fishes living on coral reefs. The Kish island have a plenty of coral reefs in around. The study was conducted on the Kish islands to identify various species of reef fishes on October 1997 to November 1998. Experiment was carried out at 77 stations around the islands. Samples were collected by underwater purse_seining, scuba diving, and using anesthetizes by injection around the fish hiding area. Results conducted that overall 113 species belong to 47 families were identified of which Pomacentridae, Acanthuridae, Scaridae and Lutjanidae are the most important in terms of number of species represented. 4 species of Apogonidae, 6 species of Lutjanidae, 11 species of Pomacentridae, 6 species of Nemipteridae, 6 species of Serranidae, 3 species of Teraponidae, 3 species of Sparidae, 3 species of Scorpaenidae, 3species of Scaridae, 3 species of Lethrinidae, 4 species of Labridae, 4 species of Gobiidae, 4 species of Chaetodontidae, 4 species of Carangidae, 2 species of Belonidae, 2 species of Balistidae, 2 species of Acanthuridae, 2 species of Tetraodontidae, 2 species of Siganidae, 2 species of Ostraciidae, 1 species of Monacanthidae, 1 species of Leiognathidae, 1 species of Atherinidae are the species presented in coral reefs at Kish island.}, Keywords = {Ornemental fish, Persian Gulf, Iran}, volume = {2}, Number = {2}, pages = {21-36}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-3178-en.html}, eprint = {http://jifro.ir/article-1-3178-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2000} } @article{ author = {Siddigui, F.A.}, title = {The larval development of Upogebia assisi Barnard, 1974 (Decapoda, Upogebiidae) reared under laboratory conditions from ovigerous femail to postlarvae}, abstract ={The ovigerous females of Upogebia (Upogebia assisi) were collected from Pacha (24o 50 54"N, 66o 43 E) on October 6 and 7, 1994 and 1995 respectively.

The establishment of accurate sex and maturity determination without external sexual dimorphism or when external characters are not developed has usually involved the use of either hormone radioimmunoassay or biopsy techniques. These methods are time and labor consuming as well as harmful to fish. Therefore, it would be economically important for caviar producing countries to develop accurate, effective and non-invasive method for determination of sex and maturity in sturgeons. Ultrasonography examination was performed to determine sex and differences between matured and immatured Acipenser stellatus. The 249 captured stellate sturgeons larger than 95 cm in length were examined with a linear transducer. Sex determination was carried out based on the differences in echogenicity and morphology of the ovaries and testes. Results of ultrasonography were confirmed at necropsy: 199 fish were female (63 matured and 136 immatured) and 50 were male (29 matured and 21 immatured). Ultrasonographic examination resulted in sex determination with 97.2% accuracy. Gonads of immature males may be difficult to discern. The speed of examination was around 30 seconds or less per fish depending on the stage of maturation of fish.}, Keywords = {Stellate sturgeon, Acipenser stellatus, Ultrasonography, Sex determination immature gonads, Mature gonads}, volume = {2}, Number = {2}, pages = {89-99}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-3183-en.html}, eprint = {http://jifro.ir/article-1-3183-en.pdf}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2000} }
