This book was released on 2006 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The arrowtooth flounder Atheresthes stomias (ATF) population in the Gulf of Alaska has increased dramatically over the past 25 years and the resulting ecosystem impacts are unclear. Arrowtooth flounder diet and prey consumption was studied to more accurately assess the predator-prey relationships of this key predator near Kodiak Island, Alaska. Temporal and ontogenetic diet trends were quantified from the analysis of 742 ATF stomachs sampled from annual bottom trawl surveys conducted in May and August from 2002 to 2004. Several significant dietary trends were found, most notably: 1) euphausiids decreased in dietary importance from May to August whereas the importance of capelin Mallotus villosus increased and 2) smaller ATF consumed more capelin and larger ATF consumed more walleye pollock Theragra chalcogramma and Pacific sand lance Ammodytes hexapterus. A bioenergetics model was used to estimate ATF prey consumption. Within the study area, the ATF population was dominated by large individuals ([great than or equal to] 50 cm total length) that accounted for > 75 % of the population's total prey biomass consumption. Arrowtooth flounder were significant predators and consumed an estimated 339 t of fish prey including Pacific sand lance and walleye pollock and 222 t of invertebrate prey such as euphausiids and shrimps"--Leaf iii.

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.

Download or read book Seafood Proteins written by Z. Sikorski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish and marine invertebrates are important sources of nutrients for the world's population, and many species have exceptionally high market value because of their exquisite sensory properties. Both the utilization of the available catch in different forms and the market price are affected by the quality of the fish. Proteins and nonprotein nitroge nous compounds playa crucial role in the nutritional value and sensory quality of seafoods as well as in the suitability of different species to various forms of processing, preservation, and use in other branches of the food industry. This role of proteins results from their basic chemical and biochemical properties and functions in different tissues. A presenta tion of the actual state of knowledge on seafood nitrogenous compounds in one volume may contribute to a better understanding of the involve ment of these components in all stages of handling and processing fish. It has been possible to prepare this text thanks to the cooperative effort of an international group of specialists. The editors of the book are greatly indebted to all colleagues who have willingly contributed to this volume, sharing their knowledge and experience, as well as to all persons who have granted permission to use their previously published materials. viii Preface ix A large part of the book has been prepared during my sabbatical in the Department of Marine Food Science, National Taiwan Ocean University (NTOU) in Keelung, Taiwan.

Available in PDF, EPUB and Kindle. Book excerpt: This publication comprises the proceedings of an international workshop convened in St. John's, Nfld, Nov. 26-29, 1979. The purpose of the workshop was to discuss the results of recent multispecies research, its applications to management, and to consider future directions for research in this field. A total of 26 papers were presented, including a combination of experience papers, state-of-the-art review, and new scientific findings. Sequential sessions were held on fisheries systems research by the Department of Fisheries and Oceans, multispecies considerations in fisheries research and management advice in the ICES area, species interactions in the Northeast Pacific and Northwest Atlantic, fisheries interactions, and applications to fisheries management. The workshop concluded with a substantial discussion of implications of present knowledge for advice to fisheries managers and implications for research program planning. The Workshop Report comprises the Chairman's opening remarks, a report on main elements of discussion in the sessions, and a summarization of workshop conclusions.
