PEIMA is the only site where the aquacultural genetic resources of INRA are maintained, selected, and conserved. Its mission to disseminate them to other experimental units. Currently, PEIMA maintains:

  • 5 strains of rainbow trout (Oncorhynchusmykiss) distinguished by their dates of egg-laying, of which one species is Golden (dominant albinism)
  • 2 strains of rainbow trout diverging in muscle-fat content (7th generation of selection)
  • 3 strains of brown trout (Salmotrutta), of which 1 has been selected for the speed of growth (9th generation of selection underway)
  • 1 strain selected for its ability to ingest plant-based feed (3rd generation of selection underway)
  • 20 strains of homozygous rainbow trout
  • 1 strain of YY males and 1 line of neo-males (XX)

A mirror site has been developed at Lées Athas. PEIMA has a European health certification that certifies it to be free of viral haemorrhagic septicaemia (VHS) and infectious hematopoietic necrosis (IHN).
