Abstract

The present study aimed at investigating the effects of 17b-estradiol valerat on gonadal sex differentiation of the rainbow trout in the absorption of yolk-sac stage and the relationship between the IMMERSION period and SEX REVERSAL percentage.To this end, 6 days after the hatching of larvae, 750 sac fry larvae were divided equally into 5 treatments. The investigation was performed in one stage and during different times in a bath containing 400 mg/lit of 17b-estradiol valerat using the IMMERSION method. The treatments were exposed to this hormone for different lengths of time: treatment 1 for 1 hour, treatment 2 for 2 hours, treatment 3 for 4 hours and treatment 4 for 8 hours. Treatment 5 was used as the control group. After using the hormone, the larvae were fed and protected to reach a suitable size and the growth of sex gonads for 4 months. After this stage, the fish in different treatments were examined for their sexes in a direct method. The results indicated that 40.40 percent of the fish in treatment 1, 41.5 percent in treatment 2, 54.3 percent in treatment 3, and 59.5 percent in treatment 4 were females. Comparing the results with the sex ratio in the control group -- that included 35 percent female fish and 65 percent male fish -- showed that immersing sac fry larvae in the bath containing 17b-estradiol valerat hormone could lead to SEX REVERSAL in this group of fish. But the hormone-treated groups didn't show a significant difference in mean weight and length as compared with the control group of the fish (p>0.05).
