5203 |a"In 1989 the Biological Sciences Branch, Department of Fisheries and Oceans, conducted a study to assess total chinook (Oncorhynchus tshawytscha) mortality in the Johnstone Strait and Juan de Fuca Strait sockeye (0. nerka) and pink (O. gorbuscha) commercial seine fisheries. Department of Fisheries and Oceans catch statistics are determined from records of salmon sales, and are suspected by some user groups to underestimate the catch of chinook by seine gear. This study independently estimated the total chinook catch in southern British Columbia seine fisheries. Total chinook mortality was estimated to be 24,285 (95% CL: 14,290-32,742) of which 3,256 were recorded as juveniles, 1,193 jacks, and 19,836 adults. Commercial records of sales for the 1989 season reported a catch of 3,348 jack chinook and 20,731 adult chinook. Total mortality in the Juan de Fuca Strait seine fishery was estimated to be 39,768 (95% CL: 26,971-51-678) of which 8,956 were juveniles, 12,019 jacks, and 18,793 adult chinook. Commercial sales slip records for 1989 reported 8,799 jacks and 14,619 adult chinook"--Abstract, page iii.
