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 Declines in Canadian Amphibian Populations written by Christine Annette Bishop and published by . This book was released on 1992 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1991, a workshop was held to examine the data related to declines in Canadian amphibian populations and associated causes and, in particular, to develop a protocol to address the issue. Participants were invited to present reports on the current status of knowledge on amphibians in Canada, particularly species that appear to be threatened. Summaries of this information are presented in this report, along with the factors that may be contributing to fluctuations in amphibian populations. Methodologies and tribulations involved in accurately assessing amphibian population size and recruitment are given. A framework for environmental monitoring was presented and the data needed, both intensive and extensive, was discussed.
Download or read book Sockeye Salmon Oncorhynchus Nerka written by Canada. Department of Fisheries and Oceans and published by Fisheries and Oceans, Information and Publications Branch. This book was released on 1987 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-day symposium was organized by the Department of Fisheries and Oceans and convened at Nanaimo, British Columbia in November 1985. Advice on subject matter and participation came from an external committee of senior scientists and administrators in contributing agencies in Canada, Japan, the United States, and the Union of Soviet Socialist Republics. The papers included in the proceedings deal with sockeye biology and stock management. Papers on sockeye biology are divided into those concerned primarily with life history strategies and enhancement and development. Papers dealing with management are divided into the tools of management and management of some principal stocks.

This book was released on 1989 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objectives of LARS were 1) To produce reliable estimates of fish yield by: a) reviewing existing estimators of production and standing stocks in large rivers and b) summarizing current river inventory and assessment techniques for biotic and abiotic variables; 2) To publish the case studies and synthesis papers; 3) To identify areas requiring further study to improve river resource management; and 4) To improve communication and liaison between scientists in research and management, university and government.

This book was released on 1994 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present publication follows an earlier report by Vermeer and Butler (1989) that described the physical and biological environment, prey organisms, and ecology of waterbirds in the Strait of Georgia. Here, we compare the year-round abundance, distribution, and energy consumption of birds in five large estuaries and one small urban estuary in the Strait of Georgia. We use the traditional definition of an estuary: the lower deltaic portion of a river and the nearby shallow waters in the freshwater plume"--Introd.
