The original intent was to describe groundfish species distributions in the area and to identify stable resident assemblages that would be amenable to multispecies production analysis and management. The survey was conducted approximately every two years with bottom trawl. This report summarizes the results from 11 bottom trawl surveys in Hecate Strait in terms of species relative biomass, area occupied, depth and spatial distribution. The utility of these indices for stock assessment and species at risk purposes is discussed.--Document392ocn060537410book20050.53Westrheim, S.

Recovery results through 1984 were published in Fargo et al. (1985). We analyzed the final recovery information for the tagging through 1999. Time at liberty was 20 years for the last recovery, and 15 recoveries were at liberty at least 10 years. During 1979-99 recovery rates were not significantly different for the two tagging grounds. Incidence of recovered tags (nos/100t) was substantially larger in Area 5D than in Area 5E. Recovery rates generally varied directly with length at tagging. The sex ratio was similar for tagged fish recovered from the commercial fishery in the two Areas, but not so in samples taken from commercial landings. There was a differential bathymetric migration of the sexes, also demonstrated in earlier studies in U.S. waters. Namely, female Dover sole tagged in "shallow" water in Hecate Strait migrated during winter into "deep" water off the west coast of the Queen Charlotte Islands for spawning. The migration of males to deepwater spawning areas preceded that of females356ocn754144930book19970.56Fargo, JA comparison of catch between research and commercial vessels during a trawl survey of Hecate Strait, May 30-June 13, 1996188ocn023651950book19900.79Fargo, JDistribution of demersal fishes in Hecate Strait, British Columbia, based on systematic trawl surveys conducted from 1984-1987147ocn071212650book19870.47CanadaGROUNDFISH STOCK ASSESSMENTS FOR THE WEST COAST OF CANADA IN 1987 AND RECOMMENDED YIELD OPTIONS FOR 1988136ocn036116522book19950.88CanadaGroundfish stock assessments for the west coast of Canada in 1994 and recommended yield options for 1995125ocn031110568book19880.56Fargo, JGroundfish stock assessments for the west coast of Canada in 1988 and recommended yield options for 1989117ocn063093951book19890.50Fargo, JGroundfish stock assessments for the west coast of Canada in 1990 and recommended yield options for 1991117ocn063068980book19890.47CanadaGroundfish stock assessments for the west coast of Canada in 1989 and recommended yield options for 199094ocn016041643book19850.92Fargo, JResults of the September 1979 Dover sole tagging experiment in northern Hecate Strait, through 1984Trawl-caught Dover sole were tagged and released in northern Hecate Strait for purposes of stock delineation.
