Nature : Fish

With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution, maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers. more...

This important book draws together, for the first time, a vast wealth of information on all major aspects of the farming of Arctic charr, a highly prized and commercially valuable salmonid. The author, Gavin Johnston who has many years' experience of farming Arctic charr, teaching about and researching the species, has produced a book that is a landmark publication and an essential purchase for all those involved with the species. The book is broadly divided into three sections. The first section covers Arctic charr interactions with humans and the charr's biological requirements for culture. Section two is a practical guide to the art and science of early-rearing Arctic charr; a hands on application of current knowledge in Arctic charr aquaculture. The final section of the book focuses on the commercial production of Arctic charr, providing cutting-edge information for all those involved in the exploitation of this valuable species. Arctic Charr Aquaculture is an essential purchase for anyone involved in, or considering involvement in farming of this species. Farm managers and other personnel in fish farms and experimental aquaculture units, fish and aquatic biologists will find a huge amount of useful data in this book. Libraries in all university departments and research establishments where aquaculture, fisheries and fish biology are studies and taught should have copies of this book on their shelves. This book brings together for the first time the knowledge needed to farm and market Arctic Charr. Part One is an overview of Arctic Charr aquaculture beginning with the history and development of Charr aquaculture, the biological attributes of Arctic Charr, the physical requirements for growth and commercial production requirements. Other chapters are devoted to Charr health, nutrition and feeding. Part Two is a practical guide for the producer operating an Arctic Charr farm either as a vertically integrated operation or as discrete hatcheries and grow out farms. more...
