Fish and shellfish comprise annually nearly 70-million tons of the world's edible animal protein. However, because of this demand, previously vast stocks have often been exhausted to the point of near extinction. The first book of its kind in the area of freshwater/marine biodiversity, this extensive work reviews the present status of genetic resource management, its needs and constraints, various intervening human factors such as pollution and overfishing, and problems posed by different species and life-styles. This discussion of the conservation of fish and shellfish resources is illustrated by four diverse groups: Atlantic salmon, cupped oysters, common and Chinese carp, and Nile tilapia. These results, produced by the collaboration of nine leading population and production geneticists, aquaculturists, and behavioral and developmental ecologists should become a fundamental resource useful to biologists, scientists and advisors exploring current issues in the fishery sciences.

Living Marine Resources provides a thorough, up-to-date introduction to all aspects of fisheries science. This clearly written text offers insight into a topic of increasing importance--the wise utilization and management of sea fisheries to maximize production without exceeding their carrying capacity. Adoption of the approaches presented will improve the conservation and management of the many world fisheries that are suffering from years of inefficient practices. The book is divided into five sections, beginning with an introduction to the ocean environment and the various resource species. Part two examines fisheries biology, including age, growth, fecundity, and mortality, enabling readers to appreciate yield models designed to give estimates of maximum sustainable yield and maximum economic yield. The third part covers gear, methods, and landings and includes material on the handling and processing of seafood as well as aquaculture. In part four, yield models are presented to introduce students to theories on population dynamics, stock assessment, and management. The book concludes with coverage of recreational fisheries, including socioeconomic importance, catch and effort research, management techniques, and their interface with commercial fisheries. Living Marine Resources is an invaluable introduction to the subject for advanced undergraduate and graduate students of fisheries science. In addition, the material presented will be valuable to fishery and social scientists, fishery officers and administrators, and students in biology, engineering, economics, and law.

Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.
Overfishing. For the world’s oceans, it’s long been a worrisome problem with few answers. Many of the global fish stocks are at a dangerous tipping point, some spiraling toward extinction. But as older fishing fleets retire and new technologies develop, a better, more sustainable way to farm this popular protein has emerged to profoundly shift the balance. The Blue Revolution tells the story of the recent transformation of commercial fishing: an encouraging change from maximizing volume through unrestrained wild hunting to maximizing value through controlled harvesting and farming. Entrepreneurs applying newer, smarter technologies are modernizing fisheries in unprecedented ways. In many parts of the world, the seafood on our plates is increasingly the product of smart decisions about ecosystems, waste, efficiency, transparency, and quality. Nicholas P. Sullivan presents this new way of thinking about fish, food, and oceans by profiling the people and policies transforming an aging industry into one that is “post-industrial”—fueled by “sea-foodies” and locavores interested in sustainable, traceable, quality seafood. Catch quotas can work when local fishers feel they have a stake in the outcome; shellfish farming requires zero inputs and restores nearshore ecosystems; new markets are developing for kelp products, as well as unloved and “underutilized” fish species. Sullivan shows how the practices of thirty years ago that perpetuated an overfishing crisis are rapidly changing. In the book’s final chapters, Sullivan discusses the global challenges to preserving healthy oceans, including conservation mechanisms, the impact of climate change, and unregulated and criminal fishing in international waters. In a fast-growing world where more people are eating more fish than ever before, The Blue Revolution brings encouraging news for conservationists and seafood lovers about the transformation of an industry historically averse to change, and it presents fresh inspiration for entrepreneurs and investors eager for new opportunities in a blue-green economy.
