Sperm quality in European eel: wild vs farmed males

Control over gamete quality is a key issue in aquaculture, both to increase productivity of commercially important fish and for the management of threatened species. One of the current challenges is to understand if and how rearing conditions can affect ejaculate quality. In order to investigate the...

Description
Summary:Control over gamete quality is a key issue in aquaculture, both to increase productivity of commercially important fish and for the management of threatened species. One of the current challenges is to understand if and how rearing conditions can affect ejaculate quality. In order to investigate the effect of captivity in European eel, sperm number and performances of six wild and seven farmed males were compared starting from 11 weeks after weekly hormonal induction. Sperm fatty acids content and plasma testosterone levels were also analysed to evaluate dietary influences and hormonal male response, respectively.
