Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Department of Fisheries and Oceans Canada, the Alaska Department of Fish and Game, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River in 2003 with a mark-recapture experiment. Fish were captured at Canyon Island on the lower Taku River with fish wheels from May through August and were individually marked with back-sewn, solid-core spaghetti tags. All tagged fish were also batch marked with an opercle punch plus removal of the left axillary appendage. Sampling on the spawning grounds in tributaries was used to estimate the fraction of the population that had been marked. The estimated spawning abundance of small Chinook salmon ( 400 mm long; mid-eye to fork of tail) was 3,489 (SE = 1,052). Spawning abundance of medium-size Chinook salmon (401-659 mm) was estimated to be 16,780 (SE = 2,274). Finally, spawning abundance of large-size fish (= 660 mm) was estimated to be 36,435 (SE = 6,705), and the estimated total of all fish was 56,704 (SE = 7,158). The sum of the peak aerial survey counts of large spawning Chinook salmon conducted at five index tributaries of the Taku River was 16% of the mark-recapture estimate. Age 1.3 fish (1998 brood year) constituted an estimated 40% of the spawning population, followed by age 1.2 fish (1999 brood year), which constituted an estimated 29% of the population

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.
