Book excerpt: The chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon fishery in the Strait of Georgia, between Vancouver Island and the mainland of British Columbia, is a valuble sport and commercial resource. In an effort to evaluate proposed regulations on sport and commercial fishermen (season closures, size limits, bag limits, etc.), a computer simulation model was developed. The model calculates the abundance and size of the natural and enhanced stocks of chinook and coho for each age-class and evaluates regulatory options by simulating the life history of these fish in half-monthly intervals. Cohorts enter the model as smolts and are followed through natural mortality, emigration out of the Strait of Georgia, fishing mortality, shaking mortality, maturation, and spawning. The major effect of any regulation that reduces catch to one user increases the catch to other users of the resource. Any attempt to increase spawning escapement without regulation of several users simultaneously is destined to failure, and even quite harsh regulations do not double the critical chinook escapement. Finally, it is found that "enhancement" of chinook and coho will lead to a more rapid decline of natural stocks unless regulations are found to reduce overall exploitation rates on these stocks.

Book excerpt: This report presents the results of the second year of data collected throughthe Strait of Georgia Port Sampling program.

In addition, there was a decrease in the shaker/keeper ratio (lower incidence of shakers) and adramatic increase in size for chinook between 1983 and 1984. Totalinterviewed catch for 1984 was 69% of the 1983 catch.
