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.

Book excerpt: Fishes of the Salish Sea is the definitive guide to the identification and history of the marine and anadromous fishes of Puget Sound and the Straits of Georgia and Juan de Fuca. This comprehensive three-volume set, featuring striking illustrations of the Salish Sea's 260 fish species by noted illustrator Joseph Tomelleri, details the ecology and life history of each species and recounts the region's rich heritage of marine research and exploration. Beginning with jawless hagfishes and lampreys and ending with the distinctive Ocean Sunfish, leading scientists Theodore Wells Pietsch and James Orr present the taxa in phylogenetic order, based on classifications that reflect the most current scientific knowledge. Illustrated taxonomic keys facilitate fast and accurate species identification.

Download or read book River of the Angry Moon written by Mark Hume and published by Greystone Books. This book was released on 2000-01-01 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Roderick-Haig Brown Prize. The Bella Coola River, now closed to steelhead fishing because the stocks are endangered, is a magnificent sight. Flowing through the stunning richness of British Columbia's temperate rain forest, the Bella Coola River is one of the worldÌs celebrated fishing streams. In this poetic and powerful book, Mark Hume describes a year in the life of the river as he fly-fishes for the fairylike whitefish, the legendary bull trout, the spirited cutthroat or the elusive steelhead. Along the way he describes the incredible beauty and fecundity of the valley ecosystem through the seasons, examines what has happened to that increasingly endangered ecosystem and its inhabitants in recent times, and encounters other anglers, old-timers who have fished the river for decades, and an abundance of wildlife. In January, Hume portrays the deep winter, when wood frogs, beetles and butterfly larvae may become frozen alive, when the snow on the mountains is stacked in steeples and when it is often too cold to fish. In June, when the river is discoloured by glacial silt and the rapids between pools deepen, he observes a clot of men fishing, their spinning rods propped on the river bank while they drink coffee, and wages a dramatic battle with a chinook salmon. And in October, he witnesses the miracle of salmon spawning, draws an intriguing parallel between commercial hunting and commercial fishing, meets a buck with tattered velvet hanging from one horn, and catches and releases a spectacular steelhead. Also available in hardcover.

Download or read book Tropical Fish Otoliths: Information for Assessment, Management and Ecology written by Bridget S. Green and published by Springer Science & Business Media. This book was released on 2009-08-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.
