Stock and fishery data for chum salmon stocks of the west coast of Vancouver Island, 1983-1987, Statistical Areas 21-27 / by S.R. Heizer.: Fs97-4/2151E-PDF

"The catch estimates for chum salmon in Statistical Areas 21-27 between 1983 and 1987 have varied between 8,500 in 1983 to 1,869,500 in 1985. Escapements varied between 236,400 in 1987 and 768,100 in 1985. Included in the report are age compositions for commercial net fisheries and test fisheries, test fishing data, estimates of both natural and enhanced production, troll catch data, Indian food fishery data, and escapement data for each stream. Commercial net fisheries have occurred sporadically and catches have been variable, with the most consistent production coming from Area 22, probably due to the enhanced run. The enhanced run in Area 25 has been less successful, and concern continues over the failure of rebuilding in unenhanced areas. New management strategies have been employed in recent years including allocating a fixed proportion of enhanced runs to the commercial fleet prior to stock assessment, and the utilization of chartered seine vessels to find harvestable surpluses to escapement"--Abstract, page xii.
