Studies on inducing sexual maturity in European eel males have been made. The fish were kept in fresh or artificial sea water at a temperature of 20°C, and hormonal injections were given. Among the hormones used, the positive results were obtained with human chorionic gonadotropin. All the male eel injected with this hormone produced sperm containing living spermatozoa. The quality of sperm of the males kept in fresh water was poorer in comparison with the sperm of the males kept in the artificial sea water.
