Book excerpt: "Non-native salmonids have been stocked into the Great Lakes since the 1870s and now naturalized populations use tributary environments to reproduce and for their juvenile life stage. Historically, brook trout were the only salmonid to inhabit the tributary environment and numerous studies suggest that exotic salmonids negatively affect brook trout by competing for limited resources. Other studies have been successful at removing non-native salmonids and the native populations increased. During this project 5,320 exotic salmonids were removed from a tributary of Lake Superior from 2008 to 2010 significantly reducing their density and young-of-year brook trout density increased by 260% the year after the study suggesting interspecific competition may be occurring. In order to monitor the salmonid populations closely, three techniques were used to assess population size of this small brook trout population. Mark-recapture estimates had large confidence intervals, so changes in population size could not be detected. Depletion estimates were hampered by sample size constraints and likely underestimated the population size. Relative abundance seemed to be the least likely to be biased because sampling was done on a frequent basis, which helped identify apparent changes in capture probability making it the best option to monitor changes in population size."--Abstract.
Book Synopsis Brown Trout by : Javier Lobón-Cerviá
Download or read book Brown Trout written by Javier Lobón-Cerviá and published by John Wiley & Sons. This book was released on 2017-12-18 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.
Book Synopsis Strategies for Conserving Native Salmonid Populations at Risk from Nonnative Fish Invasions by : Kurt D. Fausch
Download or read book Strategies for Conserving Native Salmonid Populations at Risk from Nonnative Fish Invasions written by Kurt D. Fausch and published by . This book was released on 2006 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native salmonid populations in the inland West are often restricted to small isolated habitats at risk from invasion by nonnative salmonids. However, further isolating these populations using barriers to prevent invasions can increase their extinction risk. This monograph reviews the state of knowledge about this tradeoff between invasion and isolation. We present a conceptual framework to guide analysis, focusing on four main questions concerning conservation value, vulnerability to invasion, persistence given isolation, and priorities when conserving multiple populations. Two examples illustrate use of the framework, and a final section discusses opportunities for making strategic decisions when faced with the invasion-isolation tradeoff.

Book Synopsis Estimating the Effective Number of Breeders of Brook Trout, Salvelinus Fontinalis, Over Multiple Generations in Two Stream Systems by : Matthew R. Cembrola
Download or read book Estimating the Effective Number of Breeders of Brook Trout, Salvelinus Fontinalis, Over Multiple Generations in Two Stream Systems written by Matthew R. Cembrola and published by . This book was released on 2014 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of genetic markers in monitoring populations has become increasingly important for conservation purposes, and can take many forms. While effective population size (Ne) is of great interest to conservation genetics, it may be much easier and more practical to estimate the effective number of breeders (Nb) per cohort as a tool for genetic monitoring of populations. Few studies have estimated Nb for the same species over long periods of time in comparison with demographic or environmental variables. I estimated Nb of the eastern brook trout, Salvelinus fontinalis, as part of long-term studies of two stream systems: West Brook (WB) in Massachusetts and Stanley Brook (SB) in Maine. I used eight microsatellite loci for all available young of the year (YOY) from each cohort in WB and a random subset of YOY distributed evenly throughout SB to obtain genetic-based estimates. I estimated adult abundance (NC) from mark-recapture data, and used seasonal stream flow as an environmental variable. I performed linear models with Nb as the response variable and family structure (number of families and variance in family size), NC, and seasonal stream flow as predictor variables. I found that both the number of families and variance in family size had a strong influence on Nb. Compared to abundance of adults and YOY, Nb was relatively stable over time.Stream flow in both autumn and spring showed a quadratic relationship with Nb in WB, suggesting that intermediate flows are optimal for maintaining a higher Nb. SB, with fewer years of data, did not show these relationships. If incorporated into monitoring programs, Nb can be a useful tool for detecting changes in population status and for informing management decisions.

Book Synopsis Sex Control in Aquaculture by : Hanping Wang
Download or read book Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 1969 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Book Synopsis Trout and Salmon of North America by : Robert Behnke
Download or read book Trout and Salmon of North America written by Robert Behnke and published by Simon and Schuster. This book was released on 2010-07-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.
Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
