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.

This book was released on 1989 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of the incidental catch of chinook and coho salmon from 1982-85 in pink and sockeye salmon seine and troll test fisheries in central and northern British Columbia. The use of the term test fisheries refers to vessels that were under charter to the Government of Canada and where the total catch, the location of the catch and the time of the catch were known without error. The magnitude and seasonal pattern of the incidental catch of chinook and coho salmon from the test fishing vessels were then compared with that reported for the commercial fishing fleet in the same areas.
