Book Synopsis Evaluating the Migration and Spawning Behaviors of Upper Columbia Summer Steelhead Using Radio Telemetry and Accelerometer Biotelemetry by : Nate T. Fuchs
Download or read book Evaluating the Migration and Spawning Behaviors of Upper Columbia Summer Steelhead Using Radio Telemetry and Accelerometer Biotelemetry written by Nate T. Fuchs and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding population migration trends is of importance to fisheries managers especially for populations listed under the Endangered Species Act. In recent years passive integrated transponder tags (PIT) have been increasingly used to monitor tributary escapement of adult summer Steelhead (Oncorhynchus mykiss) returning to the Upper Columbia River, but do not fully characterize behavior and survival. We evaluated the migration, overwintering distribution, and survival of Upper Columbia using radio telemetry. Additionally we monitored post spawn exit from spawning tributaries ("kelting" rate). We also analyzed the efficacy of newly developed, gastrically implanted acceleration sensing tags applied with the primary aim of detecting spawning behaviors. Using video observations, we collected movement data from telemetered steelhead within an enclosure. We developed criteria for analyzing acceleration data to infer the behaviors of tagged steelhead, released at-liberty in the natural environment. Monitoring of at-liberty steelhead revealed spawning behaviors similar to those observed among enclosure steelhead

Book Synopsis Spawning Stocks and Juvenile Summer Habitat of Rainbow Trout and Steelhead, Gulkana River, Alaska by : Thomas Christopher Stark
Download or read book Spawning Stocks and Juvenile Summer Habitat of Rainbow Trout and Steelhead, Gulkana River, Alaska written by Thomas Christopher Stark and published by . This book was released on 1999 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Gulkana River supports the northernmost population of steelhead and rainbow trout Oncorhynchus mykiss in North America. The summer habitat of Gulkana River juvenile trout (i.e., steelhead and rainbow trout) was identified and described. Analysis of geomorphological features of stream reaches (stream entrenchment, bankfull width-to-depth ratio, sinuosity, channel material, and slope) in relation to differential use of habitat by juvenile trout indicated a strong preference for type C reaches (predominately riffle/run habitat) over type E reaches (predominately slow run habitat). A comparison of micro-habitats (riffle, run, pool, slow run) within those same reaches and distribution of juvenile trout indicated a preference for riffle and run habitat. Most type C reaches in the Mainstem were sparsely populated by juveniles throughout summer. The Middle Fork was devoid of juveniles in early summer. In mid- and late summer, coinciding with the arrival of spawning chinook O. tshawytscha and sockeye salmon O. nerka, most riffle/run reaches in the Middle Fork were occupied by juvenile trout. The steelhead spawning population has declined from an estimated 200-1,000 fish two decades ago to 20-50 fish during this study (1993-1995). Rainbow trout stocks are also apparently low. Monitoring of Copper River fisheries and Gulkana spawning populations and an investigation into other steelhead spawning populations in the Copper River basin are recommended"--3.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to provide managers with national-level data on current conditions of vegetation and fuels developed from ecologically based methods to address these questions: How do current vegetation and fuels differ from those that existed historically? Where on the landscape do vegetation and fuels differ from historical levels? In particular, where are high fuel accumulations? When considered at a coarse scale, which areas estimated to have high fuel accumulations represent the highest priorities for treatment?
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.
