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.

This book is about the behaviour of teleosts, a well-defined, highly successful taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are over 22000 living species of teleosts, including nearly all the fish of importance in commercial fisheries and aquaculture. Teleosts are represented in just about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour forms the primary interface between these effective survival machines and their environ­ ment; behavioural plasticity is the key to the success of the teleost fishes. In the decade before the publication of the first edition of this book (1986) the study of animal behaviour underwent revolutionary changes under the dual impact of the new fields of behavioural ecology and sociobiology. Quantitative, experimentally-verifiable hypotheses about why individual animals behave were formulated for the first time and met with considerable success. Much of the early work in these new fields concentrated on birds and mammals, but material presented in the first edition of this book helped to demonstrate that fish behaviour is not just a simplified version of that seen in birds and mammals. but obeys the same ecological and evolutionary rules. In the five years since the first edition. much of the early theory has matured: optimal solutions to the problems of feeding and mating require subtle trade-offs of energy balance.

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.

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 certainly a candidate for calls for reinvention, with many of the world leaders in this area holding the view that no fishery has ever been properly understood or managed. With fisheries science in a state of flux, this extremely important book seeks a new paradigm that will place this flux of ideas in perspective and help us 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. Carefully integrated and edited by three of the world's leading fishery scientists, this stimulating book should find a place on the shelves of all fishery scientists throughout the world. It will be an invaluable reference source to those studying fish biology, fisheries and oceanography and all those involved in fisheries policy decisions in government and university research establishments.

The Chapman and Hall Fish and Fisheries Series occasionally includes books devoted to a single taxon of fish that are of particular interest to fish and fisheries science. All three previous books of this type (Cichlid Fishes, Cyprinid Fishes, Sea Bass) have included important material on commercial fishery exploitation, but Hake: Biology, fisheries and markets, number 15 in the Series, is the first book that focuses on a major global fishery resource. This book brings together detailed analyses of the ocean habitats, biology, ecology, assessment and management of all the hake fisheries of the world for the first time. Globally, there are ten major world fisheries for 12 species of hake on both sides of the North and the South Atlantic, the Mediterra­ nean, the eastern North and South Pacific and New Zealand. The book includes an overview of industrial markets and products of hake. Hake fisheries are of particular economic interest as their location spans almost a complete spectrum of industrial development from major industrial countries like USA, Canada, Spain and Italy through New Zealand, South Africa, Argentina and Chile to Morocco, Peru, Mauritania, Namibia and Angola.
