Fisheries-induced changes of shoaling behaviour: mechanisms and potential consequences

We outline key mechanisms by which fishing can change the shoaling tendency and collective behaviour of exploited species – an issue that is rarely considered and poorly understood. We highlight potential consequences for fish populations and food webs, and discuss possible repercussions for fisheri...
