The Great Squid Boom: Climate Change and Overfishing Rewire Ocean Food Webs

New research suggests squid populations have expanded over the last century due to warmer seas and changes in predator abundance, but the rise isn’t a straightforward replacement for depleted fish stocks. Modeling shows predator loss boosts squid, yet warmer temperatures can reduce their biomass, and the rapid squid life cycle helps them exploit disturbed ecosystems. Overall, the mechanisms are still unclear and the findings come from a bioRxiv preprint, not yet peer-reviewed.
