Abstract

The Caspian Sea is the world's largest closed lake that is very important. Bony fish is the most important and most valuable fish in the sea, which unfortunately its reserves in recent years for various reasons is declining. The present study was carried out to investigate the effect of the Stress of cavity on changes in physiological parameters effective in the Reproduction of Caspian white fish. Reproduction of fish was adapted to the new conditions for 3 days in order to adapt to the new conditions and then distributed equally to three fiberglass tanks and held for 10 days in captivity. After 10 days of storage, to the fish of first and second treatment of the sexual stimulation hormones (Ovaprim) were injected. Blood samples were taken from the samples during 3 stages. The results showed that plasma beta-estradiol 17 hormone levels were decreased after 10 days and after sexual examination in all experimental groups compared to the beginning of the experiment which, this decrease after sexual maturity was significantly higher than before the start of the experiment. Plasma testosterone levels decreased significantly in all experimental groups (P<0. 05). Changes in progesterone levels in all experimental groups were not significant (P>0. 05). Based on the results of this study, it can be stated that the stress of the cavity in the Reproduction of white fish has affected the physiological parameters studied. The relative reduction in the parameters of the examined blood plasma of these fishes shows these effects.
