Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change
Scientific India|July-August 2023
A study of 12 species of highly migratory fish predators including sharks, tuna, and billfish such as marlin and swordfish finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest-warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.

In some cases, these iconic, and economically and ecologically important species, could lose upwards of 70% of suitable habitat by the end of the century, and in most cases, the impacts of these climate-induced changes are already observable.

The ongoing and projected effects of climate change highlight the urgent need to adaptively and proactively manage dynamic marine ecosystems," according to the study. Widespread habitat loss and redistribution of marine top predators in a changing ocean," journal Science Advances.
