“Wrong-Way” Migrations Stop Shellfish From Escaping Ocean Warming

Ocean warming is paradoxically driving bottom-dwelling invertebrates – including sea scallops, blue mussels, surfclams and quahogs that are valuable to the shellfish industry – into warmer waters and threatening their survival, a Rutgers-led study shows.

In a new study published in the journal Nature Climate Change, researchers identify a cause for the “wrong-way” species migrations: warming-induced changes to their spawning times, resulting in the earlier release of larvae that would then be pushed into warmer waters by ocean currents.
