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

Available in PDF, EPUB and Kindle. Book excerpt: The North Pacific temperate rainforest, stretching from southern Alaska to northern California, is the largest temperate rainforest on earth. This book provides a multidisciplinary overview of key issues important for the management and conservation of the northern portion of this rainforest, located in northern British Columbia and southeastern Alaska. This region encompasses thousands of islands and millions of acres of relatively pristine rainforest, providing an opportunity to compare the ecological functioning of a largely intact forest ecosystem with the highly modified ecosystems that typify most of the world's temperate zone. The book examines the basic processes that drive the dynamic behavior of such ecosystems and considers how managers can use that knowledge to sustainably manage the rainforest and balance ecosystem integrity with human use. Together, the contributors offer a broad understanding of the challenges and opportunities faced by scientists, managers, and conservationists in the northern portion of the North Pacific rainforest that will be of interest to conservation practitioners seeking to balance economic sustainability and biodiversity conservation across the globe.

Available in PDF, EPUB and Kindle. Book excerpt: Rivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. - Provides a single source of information on North America's major rivers - Features authoritative information on more than 200 rivers from regional specialists - Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system - Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

Available in PDF, EPUB and Kindle. Book excerpt: Mark-recapture studies of adult Taku River sockeye salmon (Oncorhyncus nerka) stocks were conducted by the Alaska Department of Fish and Game and the Taku River Tlingit First Nation in 2003. The objectives of the studies were to provide inseason estimates of the inriver abundance of sockeye O. nerka and to document biological charactieristics (migratory timing, migratory raes and age, sex, and size composition) of Taku River sockeye stocks. Tagged-to-untaggedratios of salmon harvested in the Canadian inriver gillnet fisheries were used to develop the estimates of the inriver abundance of sockeye. A total of 5,969 sockeye salmon were captured in fish wheels located in Canyon Island, Alaska, of which 5,463, were tagged and 1,744 (31.9%) were subsequently recovered in fisheries or on the spawning grouds. The inriver run of sockeye salmon past Canyon Island from June 5 to September 17 was estimated to be 200,918 fish (95% confidence interval 180,905 to 220,931). Canadian commercial, aboriginal and test fisheries harvested 32,933, 267 and 27 sockeye, respectively, resulting in a spawning escapement estimate estimate of 167,691 sockeye salmon. Based on mean date and standard deviation of migration timing the sockeye salmon run was approximately one day earlier and more compressed than the 1984-2002 average. The Kuthai Lake sockeye salmon stocks dominated the early portion of the run, the Little Trapper Lake the middle portion, and the Tatsamenie Lake and mainstem stocks the late portion. The fish wheel catches of 15,604 pink salmon, 262 chum salmon, and 49steelhead salmon were 2.8%, 50.8% below average and 29,7% above average, respectively. The pinksalmon run was five days earlier and slightly more compressed than average.
