Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

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.
