In 1981, a program of stock identification was undertaken inorder to provide in-season estimates of stock compositions sothat more discrete harvesting of stocks could be attempted. Themajor stocks that contribute to the commercial fisheries weresampled on the spawning grounds, and electrophotectic, meristic, and morphometric characters were surveyed from each stock. Inthe present report, the authors used the electrophoreticcharacteristics of the individual stocks that were sampled on thespawning ground to estimate stock compositions in mixedfisheries.

Genetic stock identification (GIS) has occurred in Canadian chum fisheries since 1981. GIS results provide fisheries staff with stock identification information needed to effectively manage commercial fisheries. In addition, this information provides estimates of harvest by country, which are used in implementing the terms of the Pacific Salmon Treaty. This report presents the methods and results of GIS.

Genetic variability among chum salmon stocks has been used to identify the origins of chum salmon since 1981, with a genetic stock identification (GSI) program now occurring on every major chum fishery in Southern British Columbia. This report includes GSI procedures and results for the 1988 fishing season and re- analyzes the 1985-87 data due to Canada and the United States establishing a common baseline for these three years. The 1988 Johnstone Strait fishery intercepted mainly Fraser River and Johnstone and Georgia Strait returning chum stocks. The mid- Vancouver Island, Nanaimo, and Nitinat terminal fisheries were dominated by stock returning to their respective areas. A total of 6,056 chum salmon were analyzed for genetic variability over two months.
