[NEW YORK] Ocean acidification and global warming are interfering with the way fish interact in groups, posing a threat to their survival which could affect seafood supplies, researchers say.
Marine ecosystems worldwide have shown an increased dominance of warm water species following seawater temperature rise, with parallel changes in the species composition of fish catches since the 1970s, according to a report by the Intergovernmental Panel on Climate Change (IPCC).
