Fish & Sharks

Maintaining healthy fish populations is vital to our nation’s economy—important for commercial and recreational use, integral to our coastal communities, and providing healthy sources of protein. We work to ensure sustainable marine and anadromous fish populations and protect any fish species listed under the Endangered Species Act.

The Bering Sea cold pool, a bottom water mass that is < 0-2o C resulting when winter sea ice recedes affects fish movement. Warmer water temperatures and reduced sea ice in recent years resulted in shrinkage of the cold pool. Figure: NOAA Fisheries.
