Effects of xenoestrogens in eels

Vitellogenin content in Euopean eel (Anguilla anguilla) in Flanders, Belgium

Context of the study

It's known that xenobiotic substances can have effects on the endocrine system of animals. These endocrine disrupting compounds mainly come from sewage treatment effluents. However little is known the effects of these compounds on fish in Flemish waters. Through it's carnivorous lifestyle the European eel accumulates many different chemicals throughout his life. During a certain phase of his life (the yellow eel phase) the eel doesn't migrate. Therefore, analysis of residues from eels in this phase of his life would reflect the quality of the environment.
