Download or read book Estuarine Comparisons written by Victor S Kennedy and published by Elsevier. This book was released on 2013-09-25 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuarine Comparisons compares the knowledge gained about many of the world's estuaries. The book compares the Pacific, Gulf, and Atlantic coast estuaries, and the physical, chemical, and biological parameters in estuaries throughout the world. The text also compares the features of North Sea, east and West Atlantic, Gulf, and Pacific estuaries, as well as of pioneering work in the Chang Jiang estuary of China, one of the largest in the world. Comparisons of anadromous fisheries, estuarine microbiology, and many other interactive features over a wide variety of latitudinal and longitudinal variation are also encompassed. People interested in estuaries, including ecologists, will find the book invaluable.

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 The Behavior and Ecology of Pacific Salmon and Trout written by Thomas P. Quinn and published by UBC Press. This book was released on 2011-11-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Download or read book Trends in the Abundance of Chinook Salmon Oncorhynchus Tshawytscha of the Nechako River British Columbia written by and published by . This book was released on 1994 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes trends in the abundance of chinook salmon to quantify the ecological effects of water abstraction for electricity generation on the Nechako River. Trends of the escapement of Nechako chinook are compared with a composite trend derived from the abundance of chinook spawners from nearby unregulated streams. This method relies on the assumption that variation in mortality after residence in the natal stream will be similar for both the Nechako chinook and the aggregate of stocks from unregulated streams, so that any differences in population trends will be due to the effects specific to the Nechako River. The paper also tests the hypothesis that proportionately smaller flows in the upper Nechako have had a greater impact on chinook productivity compared with further downstream, where the discharge regime is closer to the historical hydrograph.
