Situation des poissons migrateurs amphihalins sur le bassin de l'adour

Abstract

The Adour River, on the Atlantic coast in SW France with a watershed of 17,000 km2, holds populations of 6 amphihaline migratory species (Atlantic salmon, sea trout, eel, two shads and sea lamprey) exploited by commercial and sport fisheries. In the early '80s, all these populations were more or less declining. Various actions (habitat improvement, population studies, stocking, fishing regulations) were undertaken during the last two decades for their enhancement, with the financial support of regional, state and European administrations and regional water agency, and with the participation of fishermen gathered within MIGRADOUR, supported technically by the CSP. This communication presents the status of the different species according to the following plan : status before 1980, actions undertaken between 1980 and 1998 and evaluation of results, current orientation.
