Associations between wintering avian predators and schooling fish in the Skagerrak‐Kattegat suggest reliance on predictable aggregations of herring Clupeaharengus
We investigated the distributional dynamics of piscivorous seabirds in relation to the distribution of young fish outside the breeding season in the Skagerrak and Kattegat, using synoptic bottom trawl and seabird surveys.
