Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Coastal populations of shellfish have been exploited by humans for millennia as an easily accessible source of fresh protein. Unfortunately, because the intertidal zone and the shallow coastal margins are so intertwined with man's activities, these shellfish stocks are now severely threatened around the world. Issues such as anthropogenic pollution, harmful algal blooms, overfishing, loss of habitat, and local stakeholder conflicts are all contributing to an alarming decline in the natural productivity of these regions. There have now been five International Conferences on Shellfish Restoration (ICSR) since 1996, which have focused the attention on transferring scientific knowledge into practical remedial and restorative actions for shellfish populations. This volume represents a selection of contributions from the third meeting in Cork, Ireland, 1999. It includes papers on lobsters, sea urchins, whelks, clams, mussels, and scallops, with a thematic emphasis on ranching, disease, environmental interactions, fisheries management, aquaculture, restoration, toxic algal blooms, and toxicity testing.

This document reviews the several fish stock assessment methods based on length-frequency analysis. Emphasis is placed on sampling and collection of length-frequency data, to the estimation of population parameters such as growth, mortality and recruitment and the estimation of catch selectivity. Attention is given to the conversion of length to age using age-length keys, slicing length-frequency composition, and using modes. It reviews long-and short-term effects of changes in selection and fishing mortality, and discusses methods for long-term assessments and for short-term projections. The manual gives several examples of the most common methods used and stresses the advantages of using personal computers and the most recent software for data processing and analysis.

Stock Assessment: Quantitative Methods and Applications for Small Scale Fisheries is a book about stock assessment as it is practiced. It focuses on applications for small scale or artisanal fisheries in developing countries, however it is not limited in applicability to tropical waters and should also be considered a resource for students of temperate fishery management problems. It incorporates a careful sample design, various mathematical models as a basis for predicting consequences for stock exploitation, and discusses the impact of exploitation on non-targeted species. This was a unique concept involving a collaborative effort between U.S. and host country scientists to address issues of regional and global concern through innovative research. Unlike other books on stock assessment that show mathematical models, this is the only book of its kind that discusses how an assessment is carried out. It looks at the field as a whole and includes sampling, age determination and acoustics. The book represents the culmination of a nine-year program financed by the United States Agency for International Development to provide new or improved methods of stock assessment for artisanal 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.

Fish are one of the most important global food sources, supplying a significant share of the world’s protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity—insights that classic age-based theory can’t provide—and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.
