✦ Synopsis
The eel migrations in Burrishoole, Ireland, have been studied from 1959 to 1988. Numbers of eels in the catches have decreased. The mean length of male eels has increased by 16.5 yo and females by 27.6 yo. Total weight of catch has not been affected by the drop in numbers. A change in sex ratio from 94.5 yo males in 1962 to 37.5 yo in 1988 has also occurred. A decrease in elver recruitment into freshwater and a change in the environmental status of the system are discussed as being possible reasons for these changes.
