Which bay in Alaska is the world's largest sockeye salmon fishery?

The bay in Alaska that hosts the world's largest sockeye salmon fishery is Bristol Bay.

Bristol Bay is a broad arm of the Bering Sea in southwestern Alaska. Its shallow waters, extensive estuaries and connected freshwater lakes and rivers create ideal conditions for sockeye salmon. The fish migrate from the Pacific into the bay and then continue upstream to the freshwater systems where they were born to spawn.

The region supports all five species of Pacific salmon found in eastern waters: sockeye, chum, coho, Chinook and pink salmon. Sockeye dominates the commercial catch, and annual returns can reach tens of millions of fish. The fishery is important not only to Alaska's seafood economy but also to Alaska Native communities, whose foodways and cultures have relied on salmon for generations.

Bristol Bay is also associated with the proposed Pebble Mine, a long-running environmental controversy because mining activity could threaten salmon habitat. Prince William Sound and Cook Inlet are also major Alaskan waters, but neither is the canonical answer to this sockeye-fishery clue.
