PEP stands for ‘Plateforme Ecophysiologie des Poissons’, Fish Ecophysiology Platform. The platform is located on two sites operated by Ifremer, one in L'Houmeau (nearby La Rochelle) and the other one in Palavas-les-flots (nearby Montpellier).

Both sites provide high standard rearing and breeding facilities dedicated to model fish or marine fish species in order to perform tox/ecotox lifecycle analysis. They can also both provide downstream phenotypic analysis (e.g. zootechnical parameters, biochemistry, gene expression and behaviour) or dispatch samples.

The two sites have some specific abilities:

  • L'Houmeau site: Rearing, breeding and exposure of model fish species – zebrafish (Danio rerio) and marine medaka (Oryzias melastigma) at any stage including reproduction. Exposure can be short and acute or chronic over a long period (e.g. 1 year-long exposure has been performed already). Early stages of marine fish can also be housed and exposed using similar rearing protocols.
  • Palavas site: Rearing, breeding and exposure of marine fish species – mainly seabass (Dicentrachus labrax) for broodstock, embryos and juveniles but also common sole.

L'Houmeau site

La Rochelle Ifremer station (located in L'Houmeau) provides facilities dedicated to ecophysiology studies (ecotoxicology and/or physiology) using small fish (fresh- and salted water model species and young marine fish). Phenotype analysis include molecular analysis, physiology, reproductive (incl. embryonic development) and behaviour characterisation.
