This investigation was conducted to determine the initial period of gonadal sensitivity to estrogen in genetically male rainbow trout (Oncorhynchus mykiss). Fish were immersed in approximately 250 microg estradiol-17beta, (E2)/l for two 2 hr periods during different stages of embryonic development beginning 30 days postfertilization (DPF) and continuing until 68 DPF. Histological analysis of gonad samples indicated a significant proportion of E2-treated fish had intersex gonads; these gonads… CONTINUE READING
