This work is concerned with the ecology of exploited fish populations. It takes a broad view of the subject, including a consideration of fish as elements in a delicately-balanced ecosystem. It also discusses the economics of fisheries in terms of a throughput of both energy and finance.

This is the second edition of an extremely important and well received book. The editor has brought together an international team of experts in the subject, producing a book which contains vital information on major aspects of this important subject. It should appear on the shelves of animal behaviourists, fish biologists and fisheries scientists.

In the past, the majority of work in animal behaviour has concentrated on birds and mammals. However, a growing body of information is now available concerning fish. In 1986 the first edition of this book was published and an ever growing demand, together with the availability of much new information, has prompted the production of this revised, rewritten and updated second edition. As well as there being an increasing interest in fish biology and fisheries for commercial reasons, fish behaviour is providing interesting data for workers in animal behaviour generally. Although constrained by the same general evolutionary and ecological rules as birds and mammals, the details of teleost behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment. "Behaviour of Teleost Fishes" reviews major topics in the subject, ranging from genetic and motivational inputs to behaviour, through the main sensory modalities, to behavioural ecology and case studies. The book also includes important information relating the behaviour of fish to their commercial exploitation.The book is aimed at those with an interest in animal behaviour, as well as workers in fish biology and fisheries.

The African lakes are an extremely important ecosystem and the subject of much study relating to species introductions and loss of biodiversity. This text examines the effect that species changes has on such ecosystems. It should be of interest to fish biologists, fisheries scientists, ecologists, freshwater biologists, conservation biologists and environmental scientists.

Over two million tonnes of hake from a dozen species are caught worldwide each year. Hake imported to the fish processing industry of developed nations is especially important in the commercial production of processed high value and high quality food. This book presents the stock biology and stock assessment, product and product development, and markets and economics of the major hake fisheries of the world. Each of the major world fisheries for hake is discussed in separate chapters by international experts. Coverage includes oceanographic features, seasonal changes, growth, migration, spawning, fleet and stock structure, current status and assessment in the fishery, current management, future prospects and the possibilities of current under-exploitation. Markets, products and quality aspects are also covered. This work should interest anyone working with the Merluccidae family of fishes, including fisheries workers, marine and fish biologists, ecologists, food scientists and technologists, purchasing and product development personnel and fish quality managers.

If judged by a dismaying track record, and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention. Fish communities are shifting towards small rapid-growing species. These symptoms have been accopmanied by a series of fisheries collapses that have not only been largely unforeseen by our most advanced assessment methods, but have also brought about disastrous economic consequences. Such things have even occurred in Canada, a nation with probably more top-rate fishery scientists "per capita" than any other. So fisheries science is now in a state of flux, and many feel it is at a cross-roads where new paradigms compete for attention and demand evidence of their utility. This book is organized into five section: why does fisheries managment need reinventing?; new policies for a reinvented fisheries management; the role of the social sciences in a reinvented fisheries mangagement; coping with ecology in a reinvented fisheries management; and modelling through in a reinvented fisheries management.

A number of major advances in our understanding of how physiological processes, and related behaviour patterns, are controlled and integrated in fish are presented in this book. Such information is not merely of academic interest since it is also fundamental to the scientific basis of fish farming and fisheries. The contributors are acknowledged experts from Europe and North America. The major themes covered are the autonomic and central nervous systems, the control of digestion, respiration and circulation, kidney function, endocrinology, and control of metabolism. Particular attention is given to reproduction in chapters on trout and teleost reproduction. Each key chapter contains much up-to-date material which will interest specialist and general readers alike.

Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is a candidate for reinvention, with many world leaders in this area holding the view that no fishery has ever been properly understood or managed. This study seeks a new paradigm that will place the flux of ideas in perspective and help to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: why does fisheries science need reinventing?; new policies; the role of the social sciences; ecology; modelling.

The African lakes are an extremely important ecosystem and the subject of much study relating to species introductions and loss of biodiversity. This book provides a thorough review of the whole subject and will be of great interest to fish biologists, fisheries workers, ecologists, environmental scientists and conservationists.
