PROJECT DESCRIPTION
BACKGROUND
Populations of Atlantic salmon differ in morphological and genetic terms according to their initial catchment area. The Loire-Allier population is the last one in western Europe to possess the qualities needed for very long migrations in freshwater environments (more than 1,000 km between estuary and spawning area), spending three years at sea to reach its adult size of over one metre, weighing up to 15 kg. At the end of the 18th century there were an estimated 100,000 individuals of this salmon species, but today only a few hundreds a year are swimming upstream to spawning areas. They are on the brink of extinction as a result of pollution, gravel extraction in their spawning area and obstacles such as dams across their migration route.
