Marine Invertebrate Fisheries

Systems Analysis and Simulation in Wildlife and Fisheries Sciences William E. Grant This hands-on approach provides guidance to the step-by-step applications of systems analysis and simulation to questions about ecological systems. At the same time, it explains general principles without requiring that readers have a strong background in mathematics, statistics, or computer science. Chapter 1 traces the development of systems ecology introducing basic concepts, while Chapters 2 through 5 present the four phases of systems analysis: conceptual model formulation, quantitative specification of the model, model validation, and model use. 1986 (0 471-89236-X) 338 pp. Bioeconomic Modelling and Fisheries Management Colin W. Clark Discusses the management of commercial marine fisheries and the relationship between the economic forces affecting the fishing industry and the biological factors that determine the production and supply of fish in the sea. Topics focus on methods of preventing overfishing and overcapitalization, economically effective and practical forms of regulation, management of developing fisheries, natural fluctuations of fish stocks, and complexities of marine ecosystems. 1985 (0 471-87394-2) 291 pp. Methods in Marine Zooplankton Ecology Makoto Omori and Tsutomu Ikeda Encompassing basic principles, procedures, and research problems, this book serves as a complete guide to current methods used in the study of marine zooplankton. The techniques are equally applicable to small organisms and to the larval stages of larger, commercially important organisms. Chapters start with a brief, but well-summarized introduction to zooplankton, followed by field sampling strategies and laboratory methods, and then conclude with estimates of productivity and analysis of community structure. Each method is described in detail, including a discussion of the problems inherent in using it. 1984 (0 471-80107-0) 322 pp. Partial table of contents:

Index. About the editor John F. Caddy has been actively involved in fisheries research and its application to managing fisheries since he completed his doctoral research on the ecology of an estuarine shellfish at the University of London twenty years ago. Much of his professional career with the Government of Canada was concerned with the population dynamics of marine invertebrates, and he is the author of numerous scientific papers on this subject. He is currently employed as Senior Fishery Resource Officer in the Food and Agricultural Organization of the United Nations in Rome, and permission from the Organization to undertake this work is gratefully acknowledged. In his present position, he has been able to draw upon his experience in a wide range of national and international fisheries in selected chapters that illustrate the main research approaches currently used in invertebrate fisheries today. Until recently, methods of assessing and managing most invertebrate fisheries have been based on empirical knowledge and procedures, supplemented in the scientific literature by assessment techniques transplanted largely unchanged from the study of finfish populations. However, considerable progress has been made over the last twenty years in our knowledge of the ecology and dynamics of exploited marine invertebrates. This volume brings the reader up to date on these developments, as well as providing a wealth of ancillary information on related areas of marine affairs. For the first time, Marine Invertebrate Fisheries brings together, in one volume, the breadth of experience gained in research and management for the wide range of commercially exploited marine invertebrates. Over thirty different studies illustrate theoretical knowledge and the practical experience to be gained in its application. It includes both case studies and chapters of general interest. All of this information is documented by reviews of current literature. This combination of study and review illustrates many applications of marine biology, as well as the associated social and economic implications of resource management and, at the same time, assesses the most promising approaches for the future. Case studies focus on crustacean fisheries for krill, lobster, crab and shrimps, and fisheries for molluscan resources such as clams, scallops, squid and octopus. Other chapters deal with echinoderms, precious corals, and rare shell harvests. Examples are drawn from tropical and temperate seas, and from arctic and antarctic ecosystems. Among the review chapters are wideranging, state-of-the-art examinations of the population dynamics of crustacean and molluscan resources—on scallops and penaeid shrimp fisheries, for example—as well as on special topics such as fisheries forecasting, the philosophy of fisheries regulation, and the principles of gear (lobster trap) design. Marine Invertebrate Fisheries will be of practical interest to a broad spectrum of readers, ranging from those in the fishing industry to the academic community, as well as members of the public concerned with marine ecology and conservation. It will be particularly valuable to experts from a range of disciplines actively engaged in marine resource management and research who will be able to draw on a diversity of examples of the practical application of marine biology to human affairs.
