Persistence of a southern Atlantic salmon population: Diversity of natal origins from otolith elemental and Sr isotopic signatures
International audience We investigated the use of Sr: Ca, Ba: Ca, and 87Sr:86Sr ratios as natural tags for determining the natal origins of juvenile and adult Atlantic salmon (Salmo salar) from 12 tributaries in the Adour basin (southwestern France) and estimated homing on a tributary scale.
