Results of the Pacific halibut (Hippoglossus stenolepis) bycatch study conducted during the British Columbia trawl fishery September 1991-December 1994 / by J. Fargo. : Fs97-4/2320E-PDF

"Data collected by onboard-observers during the British Columbia trawl fishery were used to determine catch ratios and mean CPUEs for Pacific halibut (Hippoglossus stenolepis) by target species group, season and area. Halibut catch ratios and mean halibut CPUEs were highest off the west coast of Vancouver Island, particularly when flatfish or lingcod was the target. They were lowest in the fishery off the west coast of the Queen Charlotte Islands which is primarily a rockfish fishery. They were higher in summer than in winter for most areas and differed among areas of the coast due differences in target species sought and differing fishery characteristics. Halibut catch ratios and mean CPUEs estimated for this study were generally higher than those for the last study conducted in 1981-82. …"--Abstract, page iii.
