Climate change could push migratory fish such as lamprey and shad northwards by 2100

A European project led by the University of Évora and the MARE marine research centre has modelled where migratory fish will live by the end of the century. Sea lamprey, shad, European eel and salmon are expected to lose ground in southern waters and gain it further north and in open sea, with the shifts sharper under severe warming and sometimes replacing one species with another. The DiadSea team pooled 42 datasets covering more than 468,000 sampling operations and ten species. Results should help identify areas that grow vulnerable or gain conservation value, and will be presented publicly in Évora on 15 October.
