Effective Fisheries Management Instrumental in Improving Fish Stock Status

January 8, 2020
On average, fish stocks are increasing where they are assessed

This article compiles estimates of the status of fish stocks from all available scientific assessments, comprising roughly half of the world’s fish catch, and shows that, on average, fish stocks are increasing where they are assessed. We pair this with surveys of the nature and extent of fisheries management systems, and demonstrate that where fisheries are intensively managed, the stocks are above target levels or rebuilding. Where fisheries management is less intense, stock status and trends are worse. We review evidence on the half of world fisheries that are not assessed or intensively managed and suggest their status is much worse than where fisheries are intensively managed.
