Entrainment is a process in schooling migratory fish whereby routes to suitable habitats are transferred from repeat spawners recruits over generations through social learning1. Selective fisheries targeting older may therefore result collective memory loss and disrupted migration culture2. The world's largest herring (Clupea harengus) population has traditionally migrated up 1,300 km southward wintering areas northern Norwegian waters spawn at the west coast. This conservative strategy proposed be trade-off between high energetic swimming costs enhanced larval survival under improved growth conditions3. Here an analysis of extensive data fisheries, scientific surveys tagging experiments demonstrates abrupt approximately 800-km poleward shift main spawning. new was established by large cohort recruiting when abundance critically low due age-selective fisheries. threshold required for cultural transfer probably not met-a situation that further exacerbated reduced spatiotemporal overlap driven constraints climate change. Finally, minority survivors adopted culture instead historically opposite. have profound consequences production coastal ecology, challenging management fish.
