Sex differentiation in the European eel (Anguilla anguilla L.): effects of sex steroids
Small yellow eels, 15-18 cm long, reared in warmed (22°-24°C) fresh water were treated by 17-alfa-methyltestosterone (MT) or 17-alfa-ethylestradiol (EE) given with the diet, at two different dosages and two durations. At the rearing conditions the untreated eels develop in a very large majority male...
