The Atlas of British Columbia is the first major cartographic study of the province to be published since 1956. Created through close co-operation between government, the private sector, and the unviersity, it is the successor to the British Columbia Atlas of Resources which, for twenty years, has been the standard reference work used by schools, industry, government, and the general public. The most recent data available have been used to give an accurate, comprehensive picture of British Columbia's economy as it is today. Comparative studies show the development orf the province's manpower and natural resources as well as the rapid growth of industry and technology since the beginning of the century. In party, the emphasis of the atlas reflects thousands of specific requests for up-to-date resource information rercorded over the last ten years.

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.
