Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Ecology of Salmonids in Estuaries around the World written by Colin D. Levings and published by UBC Press. This book was released on 2016-08-03 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to salt water. This book explains the critical role estuaries play in salmonid survival. Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus) explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat discuss key fitness elements salmonids need for survival (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions) provide guidance on how to conduct estuarine sampling and scientific aspects of management and recovery plans offer directions for future research. The critical reference is further enhanced by extensive supplementary appendices that are available online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.
