This book was released on 1996 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: To fulfill one objective of the present study, genetic characteristics of Oregon bull trout will be determined by analysis of mitochondrial and nuclear DNA. During 1995, the authors collected and sampled a total of 1,217 bull trout from 46 streams in the Columbia River Basin. DNA analysis of those samples will be conducted at University of Montana. They primarily sampled juvenile fish near natal areas to increase the likelihood of identifying discrete populations while minimizing risk of injury to large spawners. Fork lengths of all fish sampled ranged from 2.6 to 60.5 cm with a median of 12 cm. Eighty-four percent of all bull trout sampled were less than 19 cm while two percent were larger than 27 cm. Bull trout were collected by several methods, mostly by electrofishing. Eighty-six percent of all bull trout sampled were collected by electrofishing with a programmable waveform electrofisher. They observed injuries caused by electrofishing to 8% of that proportion. Based on preliminary analysis, no waveform combination used appeared less injurious than others. Highest voltages appeared less injurious than some that were lower. Frequency of electrofishing injury was significantly correlated to fork length over the range-from 4 to 26 cm. There were indications for substantial risk for such injury to bull trout larger than 26 cm. Other species found in association with bull trout included chinook salmon Oncorhynchus tshawytscha, mountain whitefish Prosopium williamsoni, rainbow trout Oncorhynchus mykiss, sculpins Cottus spp., cutthroat trout Oncorhynchus clarki, non-native brook trout Salvelinus fontinalis, and tailed frogs Ascaphus truei. Rainbow trout was the species most frequently associated with bull trout. No injury or mortality was observed for any of the associated species captured.
Book Synopsis Factors Influencing Spawning Migration of Bull Trout (Salvelinus Confluentus) in the North Fork Skokomish River, Olympic National Park, Washington by : Samuel J. Brenkman
Download or read book Factors Influencing Spawning Migration of Bull Trout (Salvelinus Confluentus) in the North Fork Skokomish River, Olympic National Park, Washington written by Samuel J. Brenkman and published by . This book was released on 1998 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distribution and life history characteristics of lacustrine-adfluvial bull trout (Salvelinus confluentus) were described in the North Fork Skokomish River Basin (including Lake Cushman, a reservoir) from 1994 to 1996. Day snorkeling was conducted in the river to determine initiation of the bull trout spawning migration, abundance of spawners, and duration of spawning. Declining photoperiod, increased river discharge, and decreased water temperature appeared to influence timing of migration and spawning. Lacustrine-adfluvial bull trout typically entered the North Fork Skokomish River in October although some fish entered as early as May. Mean lengths of spawners consistently increased from June to December 1996, and early migrating bull trout were shorter than those fish that entered after river discharge increased in October. The presence of two phases of the spawning migration may be indicative of two populations spawning in the river. Bull trout spawned between mid-September and December in the river and tributaries after water temperatures declined. All spawning occurred at temperatures less than 7.5°C. Comparisons with studies of other lacustrine-adfiuvial bull trout populations that inhabit river and reservoir complexes suggested that bull trout exhibit specific migratory strategies related to local environmental conditions. In the North Fork Skokomish River, changes in abundance of bull trout, mountain whitefish (Prosopium wilhamsom), cutthroat trout (Oncorhynchus dark), and rainbow trout (Oncorhynchus mykiss) revealed distinct temporal segregation among these species. Olympic National Park, a designated Biosphere Reserve, contains one of the largest remaining areas of relatively pristine habitat in the range of bull trout. Knowledge of responses of bull trout to changes in river discharge and temperature from relatively undisturbed systems, such as the North Fork Skokomish River, may be useful in understanding patterns observed in degraded environments.

Book Synopsis Upstream by : National Research Council
Download or read book Upstream written by National Research Council and published by National Academies Press. This book was released on 1996-07-17 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.
Book Synopsis Fisheries Ecology and Management by : Carl J. Walters
Download or read book Fisheries Ecology and Management written by Carl J. Walters and published by Princeton University Press. This book was released on 2020-06-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.
Book Synopsis Fisherman's Spring by : Roderick L. Haig-Brown
Download or read book Fisherman's Spring written by Roderick L. Haig-Brown and published by Skyhorse Publishing, Inc.. This book was released on 2014-03-04 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most prolific fly-fishing writers of the twentieth century, Roderick L. Haig-Brown continues his “seasons” cycle with Fisherman’s Spring, a book that is as much about the deep philosophical aspects of fly fishing as it is about fly fishing itself. Readers will learn about the abundance of spring life in the streams of British Columbia while also being treated to Haig-Brown’s thoughtful musings and ideas about the rewards of fly fishing streams. Chapters readers will encounter include: Spring Defined Early Cutthroat Lakes Fly Types The Secret Life Fishing and the Common Man On Wading Fishermen and Forestry Fishing and Milkmaids The Forecast Recognizing Birds Putting Fish Back A Boy and a Fish Pole And many more Discover within these pages how fly fishing can enrich life and bring joy to every fisher. Both novices and experts alike will find a wealth of knowledge in Fisherman’s Spring. Originally published in 1964, Fisherman’s Fall brings a unique perspective to the world of fall fishing. In the preface, Robert L. Haig-Brown ruminates on the attempts to preserve the salmon and trout in the rivers of British Columbia. What we know could save them, yet what we do contradicts that knowledge. Gaining the knowledge in this book will help fishers learn the nature of the fish and might even inspire some to contribute to their preservation. Fisherman’s Fall gives fishers all the tools to become adept at fishing the rivers of British Columbia as well as firsthand knowledge of the fish of those rivers and their habits. In fabulous prose, readers will discover the unique fishing facts and techniques that accompany the fall season, differences between salmon in salt water and fresh water, the ocean years of salmon, the nature of estuaries, steelhead mysteries, and what makes an ideal stream. Besides gathering wise information, readers get to glimpse the inner thoughts of a fisherman in the chapters of Haig-Brown’s own thoughts while fishing. These wise words will speak to any fisher, and they will even speak to those who have never been on a river. Combining angling advice and inner reflection, this book is a must-have for fishermen and fisherwomen of all ages. Skyhorse Publishing is proud to publish a broad range of books for fishermen. Our books for anglers include titles that focus on fly fishing, bait fishing, fly-casting, spin casting, deep sea fishing, and surf fishing. Our books offer both practical advice on tackle, techniques, knots, and more, as well as lyrical prose on fishing for bass, trout, salmon, crappie, baitfish, catfish, and more. While not every title we publish becomes a New York Times bestseller or a national bestseller, we are committed to publishing books on subjects that are sometimes overlooked by other publishers and to authors whose work might not otherwise find a home.
