The eelpout

There are many reasons why the eelpout is the key species in our BALCOFISH project. The eelpout is widespread in most of the Baltic regions. It constitutes an important link in the benthic ecosystem and i an important prey for other fish species and sea birds. The eelpout off the coasts spawn at the end of August and the larvae hatch approximately 3 weeks later inside the female. After about five months pregnancy, the female gives birth to about 20-250 well-developed small fish. Thus, in contrast to most fish species that lay eggs, the viviparous eelpout provides a unique opportunity to link molecular responses in the individual mother-fish to ecologically relevant reproduction parameters. The eelpout lives in stable, relatively stationary populations and observed molecular responses and ecologically relevant parameters such as reproduction thus reflect the environmental situation where the fish is caught.

Pregnant eelpout caught on the Swedish west coast in November.
