Abstract
Otolithes ruber with rather fusiform body and silver colour, has an appearance that customers like it.In order to implementation this study 45 Otolithes ruber from Abadan and Khoramshahr costal water in spawning season since December of 2013 to February 2014 were gathered randomly. After opening stomach and removing gonads and then evaluation and sexual maturation stage determination by 5 stages key (Biswas, 1997) were placed in spawning, peak of sexual maturation and after spawning. Results showed that in female species omega6 fatty acid in 3 stages including before sexual maturation (3.88± 0.96), peak of sexual maturation (6.53± 1.02) and after spawning (8.15 ± 1.03) had significant difference at 5% level maximum and minimum of fatty acid amount were related to after spawning (8.15± 1.03) and before sexual maturation (3.88± 0.96), respectively. In male Species Omega6 fatty acid has significant different in 3 stages including before sexual maturation (3.33± 0.86), peak of sexual maturation (4.93± 1.43) and after spawning (7.66± 1.44) at 5% level. Maximum and minimum of fatty acid amount were related to after spawning and before sexual maturation stages, respectively. Reproductive processing female fish, nutrition transform to oocytes in ovary during making yolk to zygot and stored there to required nutrition for zygot and newborn larva that should prepare by parents. Activity increase in fishes in sexual maturation and more energy was spent for reproductive activities and sexual maturation. Because of this storage energy supply in fish must be more that can use more energy and compensate used energy.
