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...

With the continuing decline of commercial stocks of wild-caught fish, the interest in the culture of cold-water marine fish is rapidly growing, with much ongoing research into the development of this area. This important and timely book reviews the current and potential future situation concerning the major exploited marine fish species, such as cod, haddock, hake, wolf-fish, halibut, turbot and sole. The editors of Culture of Cold-Water Marine Fish have drawn together and carefully edited chapters from a wide range of international scientists. The contents list includes detailed reviews of abiotic factors, microbial interactions, prophylaxis and disease, live food and first feeding technologies, brood stock and egg production, functional development, weaning and nursery, on-growing to market size, status and perspectives for the species covered, stock enhancement and sea ranching, and an analysis of the finances, economics and markets for the fish species used in marine aquaculture. Culture of Cold-Water Marine Fish is an essential purchase for personnel involved in marine aquaculture, whether managing fish farms, supplying equipment and feed to the industry, or researching, studying or teaching the subject. Marine biologists, fisheries scientists, fish biologists, ecologists and environmental scientists will all find much of use and interest in this timely book. Libraries in all universities and research establishments where these subjects are studied and taught should have copies. E.

Kayaking Alone is a narrative of man and nature, one-on-one, but also of man and nature writ large. In the stories of the river guides and rangers, biologists and ranchers, American Indians and dam workers he meets along the way, the rich and complicated life of the river emerges in a striking, often painfully clear panorama. Through his journey, the ecology, history, and politics of Pacific salmon unfold in fascinating detail, and with this firsthand knowledge and experience the reader gains a new and personal sense of the nature that unites and divides us. more...
