Description:This report summarizes the results of the 1990 National Marine Fisheries Service (NMFS) longline survey of the Gulf of Alaska and compares them to those of previous annual surveys. Sablefish (Anoplopoma fimbria) was the principal target species, although other commercially important groundfish populations appear to have been sampled adequately enough to derive meaningful indices of abundance and to determine the significance of changes in population size.
