The Fish Ecophysiology Platform (in french Plateforme Ecophysiologie des Poissons; PEP) is a multi-site and multi-species structure which objective is to provide space and skills dedicated to fish experiments in controlled environment.

PEP is located within two Ifremer stations La Rochelle (L'Houmeau) and Palavas. Depending on sites, PEP hosts fish model species in fresh water (zebrafish) and salted water (marine medaka) and can host exeriments performed on marine fish young stages, in L'Houmeau or large size marine fish in Palavas.
