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

Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

Download or read book Haa Aan written by Walter Goldschmidt and published by University of Washington Press. This book was released on 1998 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1940s, a boom in white migration to Southeast Alaska brought up questions of land and resource rights. In 1946, the Commissioner of Indian Affairs assigned a team of researchers to interview old and young villagers to discover who owned and used the lands and waters of the region and under what rules. Their report is published here for the first time in book form, along with text of interviews with 88 natives, a reminiscence by an anthropologist on the research team, and an introduction explaining the context and significance of the original report.

Available in PDF, EPUB and Kindle. Book excerpt: "Nelson spent a year among the Koyukon people of western Alaska, studying their intimate relationship with animals and the land. His chronicle of that visit represents a thorough and elegant account of the mystical connection between Native Americans and the natural world."—Outside "This admirable reflection on the natural history of the Koyukon River drainage in Alaska is founded on knowledge the author gained as a student of the Koyukon culture, indigenous to that region. He presents these Athapascan views of the land—principally of its animals and Koyukon relationships with those creatures—together with a measured account of his own experiences and doubts. . . . For someone in search of a native American expression of 'ecology' and natural history, I can think of no better place to begin than with this work."—Barry Lopez, Orion Nature Quarterly "Far from being a romantic attempt to pass on the spiritual lore of Native Americans for a quick fix by others, this is a very serious ethnographic study of some Alaskan Indians in the Northern Forest area. . . . He has painstakingly regarded their views of earth, sky, water, mammals and every creeping thing that creepeth upon the earth. He does admire their love of nature and spirit. Those who see the world through his eyes using their eyes will likely come away with new respect for the boreal forest and those who live with it and in it, not against it."—The Christian Century "In Make Prayers to the Raven Nelson reveals to us the Koyukon beliefs and attitudes toward the fauna that surround them in their forested habitat close to the lower Yukon. . . . Nelson's presentation also gives rich insights into the Koyukon subsistence cycle through the year and into the hardships of life in this northern region. The book is written with both brain and heart. . . . This book represents a landmark: never before has the integration of American Indians with their environment been so well spelled out."—Ake Hultkrantz, Journal of Forest History
Download or read book North Pacific Temperate Rainforests written by Gordon H. Orians and published by University of Washington Press. This book was released on 2013 with total page 0 pages. 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. Gordon Orians is professor emeritus of biology at the University of Washington. John Schoen is a senior science advisor at Audubon Alaska. Other contributors include Paul Alaback, Bill Beese, Frances Biles, Todd Brinkman, Joe Cook, Lisa Crone, Dave D'Amore, Rick Edwards, Jerry Franklin, Ken Lertzman, Stephen MacDonald, Andy MacKinnon, Bruce Marcot, Joe Mehrkens, Eric Norberg, Gregory Nowacki, Dave Person, and Sari Saunders.
Download or read book Endocrine Disruption in Fish written by David E. Kime and published by Springer Science & Business Media. This book was released on 1998-10-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
