Dealiest Catch is a documentary-style reality television series that documents the events aboard fishing boats in the Bering Sea during the Alaskan king crab and Opilio crab fishing seasons. The Aleutian Islands port of Dutch Harbor (located in Unalaska, Alaska) is the base of operations for the fishing fleet. The show is named Deadliest Catch because the crew of these boats are at a high risk of injury or death.
