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 Synopsis Risk Assessment Methods by : V.T. Covello
Download or read book Risk Assessment Methods written by V.T. Covello and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has already been written about risk assessment. Epidemiologists write books on how risk assessment is used to explore the factors that influence the distribution of disease in populations of people. Toxicologists write books on how risk assess ment involves exposing animals to risk agents and concluding from the results what risks people might experience if similarly exposed. Engineers write books on how risk assessment is utilized to estimate the risks of constructing a new facility such as a nuclear power plant. Statisticians write books on how risk assessment may be used to analyze mortality or accident data to determine risks. There are already many books on risk assessment-the trouble is that they all seem to be about different sUbjects! This book takes another approach. It brings together all the methods for assessing risk into a common framework, thus demonstrating how the various methods relate to one another. This produces four important benefits: • First, it provides a comprehensive reference for risk assessment. This one source offers readers concise explanations of the many methods currently available for describing and quantifying diverse types of risks. • Second, it consistently evaluates and compares available risk assessment methods and identifies their specific strengths and limitations. Understand ing the limitations of risk assessment methods is important. The field is still in its infancy, and the problems with available methods are disappoint ingly numerous. At the same time, risk assessment is being used.

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.

This book was released on 1996-07-31 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwest--economic, recreational, symbolic--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 runs--and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problem--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 geography--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 activities--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 issue--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.
