A Study was carried out on spawning season, feeding and some environmental conditions of 8 aquatic species of Hormozgan sea waters from Oct. 91 to Mar. 93. The results showed that spawning peak for otolithes ruber, Psettodes erumei, Pomadasys kaakan, Arius thalassinus and Arius tenuispinis occured in spring, for Pampus argenteus and Parastromateus niger occurred in summer, and for Sopia pharaonis occurred in Autumn. Two summer spawner and two Arius species were appeared Lo he very gluttonous and other spring spawner species showed rather less tendency for feeding P.argenteus appeared to eat copepod and rhizosolenia and P.niger stomach contents included nematod and annelid worms and also copepod, P.erumei feeds on small fishes and others eat crustaceae and small fishes too. High growth coefficients for P.argenteas and A.renuispinnis a medium growth coefficient for P.niger and low growth coefficients for other species were obtained. Except for S.pharaonis, geographical distribution .....
