A trade association representing the Bering Sea bottom-trawl fleet has filed a lawsuit against the new halibut bycatch limits, arguing they are unfair and unlawful, and could result in drastic economic consequences. The lawsuit was filed in response to the new limits, which are set to go into effect on Jan. 1, by Groundfish Forum, which represents five companies and 17 bottom-trawl vessels. Surveys indicate that halibut stocks off the coast of Alaska have declined over the past 15 years, and while federal fisheries managers say that reduced bycatch levels may see additional halibut harvests, the International Pacific Halibut Commission projects further declines of spawning females.
