The text is intended as supplementary reading for fisheries workers, especially in developing countries, who do not always have ready access to current literature on applied marine ecology. An attempt is made to develop a wide range of concepts in a form that will hopefully encourage their incorporation into a practical, decision-making context. The food web and associated trophic interactions form the principal theme, in an approach that gives equal emphasis to qualitative, as well as the less easily measured quantitative considerations. An attempt is made to illustrate the consequences of the aggregated nature of much of marine production, as well as the subsequent dispersal of production in space and time, and how these processes affect the potential for economic harvest of commercial components of the ecosystem. Separate sections touch on environmental influences on production, relevant spatial and temporal scales for ecosystem analysis, life history strategies, diversity and stability, the concepts of the ecological niche, the community and the assemblage, and outline some first steps towards quantifiying production in marine ecosystems. Different approaches to representing trophic and other interactions are discussed, with examples from the literature. Reference is made to several ecological subsystems, in order to illustrate the main concepts presented. These include the mangrove ecosystem, the arcto-boreal macrophyte community, a mediterranean demersal fish assemblage, and the oceanic ecosystem associated with high seas tuna stocks. In practical terms, it is concluded that the first and simplest approach to multispecies resource management is not necessarily the manipulation of individual food web components, but the identification, mapping and conservation of critical habitats, especially centres of local production, and their associated ecological dissipation structures.

"The annual global catch of tropical or "penaeid" shrimp amounts to 700,000 tons. Some of the largest fisheries for shrimp appear to be in waters off Indonesia, Thailand, India and in the Gulf of Mexico. Shrimp are extremely valuable, often of importance for domestic use, but also as a valuable export item. The great value of the shrimp emphasizes the importance of shrimp management, especially since substantial increases in global shrimp production are not expected, hence, making it important to improve management and make most efficient use of stocks in existing fisheries"--Introduction, paragraph 1

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.
