Ocean Warming Linked to Nearly 20% Annual Fish Biomass Decline, Global Study Finds
Chronic ocean warming is driving a sustained annual decline of nearly 20% in fish biomass across major marine regions, according to new research published in Nature Ecology & Evolution.
The study, conducted by scientists from the Museo Nacional de Ciencias Naturales (MNCN-CSIC) and the National University of Colombia, analyzed 702,037 biomass change estimates from 33,990 fish populations recorded between 1993 and 2021 across the Northern Hemisphere.
