Cold seawater induces early sexual developmental stages in the BPG axis of European eel males.

ABSTRACT:

Background

The impossibility of closing the life cycle of the European eel (Anguilla anguilla) in captivity troubles the future of this critically endangered species. In addition, the European eel is a highly valued and demanded resource, thus the successful closing of its life cycle would have a substantial economic and ecological impact. With the aim of obtaining the highest gamete quality, the study of the effects of environmental factors, such as temperature, on reproductive performance may prove valuable. This is especially true for the exposure to cold water, which has been reported to improve sexual development in multiple other Actinopterygii species.

Results

European eel males treated with cold seawater (10 °C, T10) for 2 weeks showed an increase in the proliferatio
