Book Description
The farming of aquatic organisms is one of the most promising but controversial new industries in Canada. The industry has the potential to solve food supply problems, but critics believe it poses unacceptable threats to human health, local communities, and the environment. This book is not about the methods and techniques of aquaculture, but it is an exploration of the controversy itself. The authors present the controversy as a multi-layered conflict about knowledge, rights, and development. Comprehensive and balanced, this book addresses one of the most contentious public policy and environmental issues facing the world today.

Book Description
This discussion paper on Canadian aquaculture was prepared by the federal Department of Fisheries and Oceans (DFO), for review with Provincial Government officials, as one of several agenda items at the following meetings: the Federal-Provincial Freshwater Fisheries Committee (comprising DFO, Alberta, Saskatchewan, Manitoba, Ontario and the Northwest Territories) held Sept. 18, 1985 in Regina; the Federal-Provincial Atlantic Fisheries Committee (comprising DFO, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador) held Oct. 18, 1985 in Mont Ste. Marie; and the Federal-Provincial British Columbia Fisheries Committee (comprising DFO and British Columbia) held Oct. 22, 1985 in Vancouver. In those meetings, there was general agreement that DFO and the provinces should work closely to facilitate the development of the commercial aquaculture industry in Canada. Follow-up discussions have been ongoing to sort out the basis for that cooperation, as well as specific initiatives in each Province. This document is now being released because of the growing public interest about the potential for the aquaculture industry in Canada.

Book Description
Volume 3. This document identifies elements of a legislation that will encourage the emergence of a sustainable commercial aquaculture. The aquaculture law of an individual country must provide the operator with a secure right to conduct aquaculture operations, to the property on which the farm will be located, to good quality water and to the produce. It must also ensure environmental sustainability, through permit or licence systems, without imposing unnecessary costs on applicants. Only proposals with the potential for serious environmental harm should be subjected to a full environmental impact assessment. Environmental supervision must extend to controls over the use of exotic species and products from modern biotechnology including genetically modified organisms, disease control and health management and to any water quality concerns created by the proposed project. To minimise costs, countries are encouraged to adopt a single window approach for the numerous approvals usually required for an aquaculture operation and screen initial applications. They could also consider creating a single agency to promote aquaculture and to monitor the progress of applications. Aquaculture regimes of selected African countries are measured against the elements required to encourage sustainable commercial aquaculture, and improvements that are applicable to all countries in sub-Sahara are suggested.

Book Description
As traditional commercial fishing becomes increasingly expensive and restrictive, aquacultural fish production emerges as a practical viable alternative. The Aquaculture Sourcebook is an introductory text and ready reference for information on the fresh-, brackish-, and salt-water farming of both fish and shellfish, as well as of several important algae. Until now, such material has been available only in scattered publications; but the Aquaculture Sourcebook incorporates all the feasibility data pertinent to farming aquacultural species in North America into one easy-to-use text. It will be welcomed not only by current and future aquaculturists, but also by fisheries, seafood company managers, biologists, teachers, and students. The Aquaculture Sourcebook has been designed to satisfy the needs of fisheries, scientists, and commercial aquaculturists by providing, in a handy and well-organized format, information vital for successful North American aquacultural ventures. Concise details are given for over a hundred individual speices, including not only those raised for human consumption, but also organisms reared for feed, bait, or other purposes. Each entry in this valuable volume covers such relevant material as: *the scientific and common names of the organism *its visual appearance and distinctive characteristics *habitat range specifications *species reproduction and development *age- and growth-related factors *specific parasites an diseases *potential predators and/or competitive species *its prospects for future aquacultural success Key groups of closely related species are discussed in a geographical context, highlighting areas which each will find the habitat best for its survival. Great care has been taken to specify ranges of tolerable salinity and optimum temperature for candidate species, and emphasis has been placed on creating aquacultural environments that replicate those normally habitated in nature. Comprehensive, informative, and accessible to layperson and scientist alike, the Aqualculture Sourcebook is both the perfect desktop reference for anyone establishing an aquacultural facility, and a ready reference to help maintain one.

Book Description
This book deals with Canada's oceans management policies since the conclusion of the 1982 Convention of the Law of the Sea. That Convention set out a jurisdictional framework for the management of the world's oceans, but it did not provide states with precise guidance on all the issues that can arise. As a state with one of the world's longest coastlines, Canada was one of the principal beneficiaries under the 1982 Convention regime. A study of Canadian policy is particularly significant, as Canadian oceans management places in relief many of the difficult questions yet to be resolved.

Book Description
This important book draws together, for the first time, a vastwealth of information on all major aspects of the farming of Arcticcharr, a highly prized and commercially valuable salmonid. Theauthor, Gavin Johnston who has many years' experience of farmingArctic charr, teaching about and researching the species, hasproduced a book that is a landmark publication and an essentialpurchase for all those involved with the species. The book is broadly divided into three sections. The firstsection covers Arctic charr interactions with humans and thecharr's biological requirements for culture. Section two is apractical guide to the art and science of early-rearing Arcticcharr; a hands on application of current knowledge in Arctic charraquaculture. The final section of the book focuses on thecommercial production of Arctic charr, providing cutting-edgeinformation for all those involved in the exploitation of thisvaluable species. Arctic Charr Aquaculture is an essential purchase foranyone involved in, or considering involvement in farming of thisspecies. Farm managers and other personnel in fish farms andexperimental aquaculture units, fish and aquatic biologists willfind a huge amount of useful data in this book. Libraries in alluniversity departments and research establishments whereaquaculture, fisheries and fish biology are studies and taughtshould have copies of this book on their shelves. This book bringstogether for the first time the knowledge needed to farm and marketArctic Charr. Part One is an overview of Arctic Charr aquaculturebeginning with the history and development of Charr aquaculture,the biological attributes of Arctic Charr, the physicalrequirements 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 ArcticCharr farm either as a vertically integrated operation or asdiscrete hatcheries and grow out farms. Part Three is devoted tothe business of commercially producing Arctic Charr, and althoughit deals specifically with Charr it also covers many businessaspects of farming relevant to any fish species under cold watercultivation. It covers farm business management, the economics andfinance of Arctic Charr farming, marketing Charr products and aclosing section on how to avoid the pitfalls which others includingthe author have experienced.

Book Description
Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the ‘green revolution’ before it, the ‘blue revolution’ in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture’s ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam,nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).
