Alaska Pollock

Also known as Walleye Pollock, Pacific Pollock, Bigeye Pollock

Alaska pollock form vast, shimmering schools that dominate the pelagic waters of the North Pacific and Bering Sea, serving as the central hinge of the subarctic marine food web. Adults undertake seasonal migrations between deep overwintering shelf waters and shallow coastal spawning grounds, where females broadcast hundreds of thousands of eggs into the current. Their extraordinary biomass sustains apex predators across the region and fuels the largest single-species commercial fishery on the planet.
