Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance. Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins. With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Why are some marine fish super abundant, attracting the attention of commercial fisheries? The full answer to this question can only be found by looking not just at biological aspects, such as reproduction and population dynamics, but also at the surrounding oceanic conditions, by analysing physical, chemical, geomorphological and other data. The sciences of fisheries and oceanography have in the past followed separate developments, but with the advent of the new science of fisheries oceanography, oceanographic information is being used to solve ecological problems in fisheries. Fisheries Oceanography provides thorough coverage of the major aspects of this important subject. The editors of this text book have drawn together an impressive list of contributing authors who offer vital insights into early life history, migration, genetic variability, climate change effects, models and the use of satellites in fisheries oceanography. An important aspect of the book is the inclusion of chapter commentaries by leading world authorities. The book concludes with an overview of problems facing fisheries, and how fisheries oceanography can be utilized to resolve some of these problems in the future. Fisheries workers, oceanographers and marine scientists will find a great deal of current information vital to their work in Fisheries Oceanography. As a text book it will be of great use to all those studying and researching marine fisheries, including BSc, MSc and other postgraduate students particularly in fisheries, fish biology, marine biology, oceanography and ecology.

The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery catch data. This groundbreaking information has been gathered from independent sources by the world's foremost fisheries experts. Edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project, the Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. Each national report describes the current state of the country's fishery; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations.

Unique in the reference literature, this Companion provides students with an introduction to all the major concepts and contemporary issues in the environmental sciences. The text is divided into six sections (Environmental Sciences, Environments, Paradigms and Concepts, Processes and Dynamic, Scales and Techniques, Environmental Issues), with over 200 entries alphabetically organized and authored by key names in the environmental science disciplines. Entries are concise, informative, richly visual and fully referenced and cross referenced. They introduce key concepts and processes that are included in the index, cite relevant websites, and reflect the latest thinking.

Scallops are among the better known shellfish and are widely distributed throughout the world. They are of great economic importance, support both commercial fisheries and mariculture efforts and occupy a unique niche in the marine environment. Contributions from world leaders in scallop research and culture cover all facets of scallop biology including anatomy, taxonomy, physiology, ecology, larval biology and neurobiology. Chapters are also devoted to diseases and parasites, genetics, population dynamics and the adductor muscle, with extensive reference lists provided for each chapter. Since the publication of the first edition of Scallops: Biology, Ecology and Aquaculture in 1991, commercial interest in scallops has grown globally and this is reflected in the seventeen extensive chapters covering both fisheries and aquaculture for all species of scallops in all countries where they are fished or cultured. The Second Edition is the only comprehensive treatise on the biology of scallops and is the definitive reference source for advanced undergraduate and graduate students, mariculturists, managers and researchers. It is a valuable reference for anyone interested in staying abreast of the latest advances in scallops. * Offers over 30 detailed chapters on the developments and ecology of scallops* Provides chapters on various cultures of scallops in China, Japan, Scandinivia, Eastern North American, Europe, and Eastern North America* Includes details of their reproduction, nervous system and behavior, genetics, disease and parasites, and much more* Complete updated version of the first edition
