"In 1990 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 (O. nerka) and pink (O. gorbuscha) 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 in the Johnstone Strait seine fishery was estimated to be 11,134 (95% CL: 7,238-16,039) of which 983 were juveniles, 2,347 jacks, and 7,804 adults. Commercial records of sales for the 1990 season reported a catch of 1,717 jack chinook and 12,154 adult chinook. Total mortality in the Juan de Fuca Strait seine fishery was estimated to be 20,037 (95% CL: 10,867-31,102) of which 9,120 were juveniles, 4,175 jacks, and 6,792 adult chinook. Commercial sales slip records for 1990 reported 4,743 jacks and 5,753 adult chinook"--Abstract, page iii. Includes abstracts in English and French.
