Climate-driven zooplankton shifts cause large-scale declines in food quality for fish

Nature Climate Change, Published online: 23 March 2023; doi:10.1038/s41558-023-01630-7

Using a trait-based model that resolves key zooplankton groups, the authors reveal future shifts to food webs dominated by carnivorous and gelatinous filter-feeding zooplankton. Subsequent decreases in food nutrition are linked to declines in small pelagic fish biomass, particularly in tropical regions.
