Excerpt from Escape of King Crab, Paralithodes Camtschatica, From Derelict Pots
Loss of 10% per season of pots (traps) in the Alaskan fishery for the king crab, Paralithodes camtschatica, has raised the question of possible loss of crabs and fishes to the derelict. Or lost, pots which continue to fish. We conducted a series of experiments during 1974 and 1975 in which tagged king crab were placed in several types of pots and returned to the bottom (soaked) for periods of 1-16 days. As controls. We released some tagged king crab in Chiniak Bay, Kodiak Island, Alaska. Tagged crab missing from the pots at time of recovery were credited with escape.
