Climate-driven feed shortages could cut aquaculture by 35%

Aquaculture — the world's largest source of seafood — will need an additional 1.8 million metric tons of alternative feed ingredients to keep pace with demand and the impacts of climate change, according to a study published late last year in the journal Nature Food.

According to the study, climate change and corresponding changes in fishery management could reduce global forage fish catches by 4.5% to 19.4%, potentially causing an 8% to 35.2% decline in global aquaculture production.
