This book provides cutting-edge scientific idea and novel concepts on the ecosystem-based approach to fisheries management. It begins by reviewing the scientific fundamentals and problems currently faced by conventional fisheries science, based on population dynamics. In turn, it reviews the theoretical basis of ecosystem dynamics, including selected ecosystem indicators. Surplus production and balanced harvests are discussed in the ecosystem dynamics context. Several ecosystem-holistic indicators are described, but particular emphasis is placed on two: the noxicline (gain in entropy due to loss of biomass) and resilience, which are expressed as ecosystem (holistic) points of reference for defining allowable harvest rates. Both biological (population) and ecosystem (holistic) points of reference are subsequently analyzed in the context of fisheries management and conservation. An adaptability concept is also discussed as a management policy for facing climate change. In closing, the concepts presented are applied to six study cases involving a range of different ecosystems and fisheries.

This auto-translation book overviews the fish population and its research methods, help readers in understanding the concept of fish population and population identification.

This cutting-edge book presents novel strategies to meet the growing demand for vaccines in finfish aquaculture. The book is useful to students, academics, clinicians, and professionals in the field of fisheries sciences, aquaculture, and veterinary sciences.

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.

A comprehensive review of current knowledge of the deep-water fishes of the North Atlantic and their exploitation. Individual countries and research institutions have carried out their own investigations and surveys in the past, but these results have rarely been coordinated, nor has there been a proper sharing of results and data. But there is a need to assess the total size of the deep-water stocks and the extent to which they can safely be exploited. The book also contains a number of papers describing present and past research and the present exploitation of resources, together with papers on the technical problems encountered in capturing and processing these fishes. An assessment of the requirements for future research is presented.

This book deals with the bottom-living fishes of the world's largest ecosystem, the deep-sea. After a brief review of the oceanographic setting, the diversity and ecology of this unique ichthyofauna are considered in detail. The book goes on to deal explicitly with slope fisheries, both developed and developing. The interaction of the ecology of the species involved (examples include orange roughy, grenadier, Greenland halibut and black scabbardfish) with fishing practices and management regimes is then discussed. An ecological framework for management is necessary for the resources to be sustainable it is argued, rather than simply extending approaches used on the Continental Shelf to the deep-sea.

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 ofconsiderable importance to the survival ofthe human species in the form of nutritious and delicious food of numerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and 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 ofnon specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries."

The ciliated protozoa are important members of the interstitial biotope by virtue of their numbers and biomass. These single celled organisms form complex communities in the spaces between sandgrains in many marine sediments. Despite their important role in benthic ecology, there has been a lack of detailed studies on this large and fascinating group. Although difficult and demanding to work with, the most important aspect that has hampered research on these fragile organisms has been the lack of a suitable identification guide. This book describes all the specialized techniques necessary for the collection and transport and covers in detail many laboratory procedures that have been developed for these organisms. The bulk of the book is taken up by an identification guide to all species inhabiting marine sands worldwide. Diagnostic keys to 67 families, together with 179 generic descriptions are followed by keys to all 937 species considered valid. Detailed species descriptions are given, many in English for the first time, together with all essential diagrams in a total of 108 plates. The keys are easy to interpret and there is a glossary of specialist terms. There is a list of references and a systematic index to all species and their synonyms. A diagnostic key to species is a useful prerequisite to further studies of the ciliates, consequently this key has been eagerly awaited by many workers in marine life sciences. This guide should enable both specialist and non-specialist to identify to species level and should be fundamental to future meiobenthic research. This book should be of interest to research and professional marine biologists, ecologists and marine microbiologists.

The presence of concentrations of organic substances and cations in sea water is a matter of increasing concern to the water industry, environmentalists and the general public alike. There is a threat of possible health hazards to both human, fish and crustacea. Occurrence, Toxicity and Analysis of Marine Biota discusses bioaccumulation in biota as well as occurrence and analysis of toxicants in biota. The main thrust of this book will be a review of the levels of toxicants found in the tissues of fish and invertebrates at various sites throughout the world. In addition, results will be reported on the levels of toxicants found in marine biota enabling ill health or death to occur. This will involve a discussion of toxicity index LC50 and percentile S95 concentration of toxicants and their implications on animal health and mortality, also that of humans who eat these sea creatures. The book will be a complete logical survey of this topic.

This comprehensive book brings together experts from both the marine science and pharmacy disciplines to relay important aspects on the pharmaceutical and nutraceutical values of 175 species of bony and cartilaginous fishes as well as the uses of fish processing byproducts and wastes.Presented in an easy-to-read style, the volume provides precise identification of freshwater and marine fishes possessing pharmaceutical and nutraceutical compounds along with over 180 photographs. Aspects covered include biology, ecology, diagnostic features, and pharmaceutical and nutraceutical compounds along with their activities for each of the fish included. The book details the bioactive compounds, including fish muscle proteins, peptides, collagen and gelatin, fish oil, etc., from such species, as well as the bioactive peptides that are derived from various fish muscle proteins, which have various biological activities, including cardio protective, antihypertensive, anticancer, anti-diabetic, antibacterial, anticoagulant, anti-inflammatory, and antioxidant activities. Also discussed are the nutritional benefits of fish consumption, which are largely due to the presence of proteins, unsaturated essential fatty acids, minerals, and vitamins. The waste products obtained during fish processing are also a potential source of bioactive peptides that can be used as a source of nitrogen and amino acids, which have immunomodulatory, antibacterial, antitrombotic, and antihypertensive properties. This volume provides the information needed to tap into these vast pharmaceutical and nutraceutical benefits. Pharmaceuticals and Nutraceuticals from Fish and Fish Wastes will be of great use for students and researchers of disciplines such as pharmaceutical sciences, marine/fisheries sciences, marine microbiology, and marine biotechnology.

To date textbooks on viruses infecting fish, crustaceans and molluscs, the three main aquatic animal farmed groups, have been on the whole "diseases-centric" and individual viral diseases selected based on "epizoo-centric" approaches with little to no coverage of the basic biology of the viruses, in contrast to textbooks on viruses infecting terrestrial - farmed, pet, and free-range (wild) - animals and humans. Despite considerable advances in animal virology in recent years coupled with an economically important global aquaculture industry, knowledge of viruses of animal aquaculture is still sparse and in some cases outdated although these viruses are closely related to well-known virus families. The last book in fish virology (Fish viruses and fish viral diseases 1988, Wolf, K.) was published in the 1980s. A lot of work has been done on fish viruses and many new aquatic animal viruses continue to be discovered. Aquaculture Virology provides the current state of knowledge of aquatic animal viruses within the current virus classification and taxonomic context thereby allowing the reader to draw on the principles of general virology. This book is a systematic and concise resource useful to anyone involved with or looking to move into aquaculture and fisheries. Clinical veterinarians, aquaculture disease practitioners, biologists, farmers, and all those in industry, government or academia who are interested in aquatic animal virology will find this book extremely useful.
