The brown trout and quantitative ecology -- The brown trout: a successful polytypic species -- Case-study: population dynamics of migratory brown trout in Black Brows Beck, 1966-90 -- Growth and energetics of brown trout -- Case-study: growth and production of migratory brown trout in Black Brows Beck, 1966-90 -- Ecological differences between brown trout populations -- Natural selection and genetic differences between brown trout -- Mechanisms responsible for population regulation in young brown trout -- General conclusions. "This book provides, for the first time, a synthesis of quantitative information on the ecology of the brown trout, including seatrout, and comparisons with closely related species such as Atlantic salmon, Pacific salmon, and rainbow trout. Much of this work, especially the case studies, is relevant to general problems in quantitative animal ecology as well as to fisheries management. One theme emphasized throughout is the development, testing, and use of realistic mathematical models as important tools for consecration and management of fish and other animals." "The first eight chapters deal with: the global success of the polytypic brown trout; growth and energetics; natural selection and genetic differences between individuals and populations; population dynamics of both adults and juveniles; and detailed case studies of one sea-trout population in the English Lake District. The ninth chapter highlights the main conclusions that can be drawn from the earlier chapters and identifies remaining major gaps in knowledge. This volume will be of interest to all students of population ecology and fish biology, and especially to biologists engaged in managing fisheries." "Few books illustrate so well the value of long-term studies in ecology."--Jacket.
