The responsiveness of the non-vitellogenic Singi fish to exogenous estrogen has been studied at different environmental temperatures. Estrogen was found to be effective in fish kept at 25 degree C and 30 degree C, as evidenced from the increase in hepatosomatic index (HSI), plasma protein and liver protein and RNA contents, and a fall in liver glycogen content after injections of estradiol dipropionate (1 microgram/g) for 7 consecutive days. Such estrogen-induced changes were not observed in the fish kept at 15 degree C, indicating the ineffectiveness of this sex steroid at this lower temperature.
在不同环境温度下研究了未产卵的辛吉鱼对外源雌激素的反应。发现雌激素对饲养在25摄氏度和30摄氏度的鱼有效，连续7天注射二丙酸雌二醇（1微克/克）后，肝体指数（HSI）、血浆蛋白、肝脏蛋白和RNA含量增加，肝脏糖原含量下降，证明了这一点。在饲养于15摄氏度的鱼中未观察到这种雌激素诱导的变化，表明这种性类固醇在较低温度下无效。
