The recent Canada/U.S. Pacific Salmon Treaty significantly influenced the management of B.C.'s commercial and sport fisheries. This report integrates all recent and reliable information on B.C.'s major troll fishery into an analytical tool to evaluate management options. The study included extensive analyses of coded wire tag recovery data for information on the distribution and migration timing of chinook and coho stocks; assessment of whether troll catch per effort data could be used to provide in-season estimates of diversion rates for sockeye and pink stocks vulnerable to Johnstone Strait and West Coast Vancouver Island fisheries; and the organization of reliable catch, effort and fish age data for south coast sport and troll fisheries. The results of these analyses were used to update the Georgia Strait Chinook and Coho Model and develop a simulation model for the West Coast Vancouver Island troll fishery. This report presents the results of data analyses, and describes the structure and function of the West Coast Vancouver Island Management model.
