Abstract
Gonadal development was investigated in 58 European eels of known age kept in aquaria in stable conditions optimal for growth (except for light). Sex of fish was determined by histological analyses of gonads, the results of which were checked by kariological analysis. It was found that: 1. 1) Sex differentiation in European eels is connected with size of fish and not age and begins when eels reach 10 cm in length. 2. 2) Gonads of the European eel do not pass through a stage of juvenile hermaphroditism.
