ANR SALTEMP  "Global warming and adaptation of migration in Atlantic salmon from long river Loire-Allier Axis"/“Réchauffement global et adaptation à la migration chez le saumon atlantique de longue rivière, l’axe Loire-Allier”

Programme ANR BIOADAPT (Adaptation des gènes aux populations. Génétique et biologie de l’adaptation aux stress et aux perturbations)

Ref Projet: ANR-12-ADAP-0021

The sustainability of Atlantic salmon Salmo salar of the basin Loire/Allier is now threatened. The conservatoire National du Saumon Sauvage (CNSS), partner of this project, capture wild brood stocks to ensure reproduction and restocking of this emblematic unique strain. However there is a narrowing of the most favourable window for downstream migration. This is due to a combination of factors including long-distance migration (900 km), obstacles and now warming, due to global climate change and local human activities. This project aims to elucidate the environmental and neuroendocrine mechanisms of preparation and initiation of downstream migration of wild salmon from the Loire/Allier basin and the impact of global warming on these processes.
