Abstract
The European silver eel (Anguilla anguilla L.) obtained from the Egyptian Lake (Burollos) gave positive results when the males were induced by a human chorionic gonadotropin hormone (HCG). Males maintained in metallic tanks, supplied with sea water (salinity 37.5 ppt) and diffused atmospheric air showed a response to hormone injections. Testes attained their nearly ripe condition after the 5th injection and full testicular ripeness and consequent spermiation were achieved after the 7th injection, in a period of 45 days. Several morphometric and biological changes occurred with increasing the successive injections.
