The Aquaculture Controversy in Canada by Nathan Young,Ralph Matthews Pdf
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.
NATIONAL BESTSELLER Alexandra Morton has been called "the Jane Goodall of Canada" because of her passionate thirty-year fight to save British Columbia's wild salmon. Her account of that fight is both inspiring in its own right and a roadmap of resistance. Alexandra Morton came north from California in the early 1980s, following her first love--the northern resident orca. In remote Echo Bay, in the Broughton Archipelago, she found the perfect place to settle into all she had ever dreamed of: a lifetime of observing and learning what these big-brained mammals are saying to each other. She was lucky enough to get there just in time to witness a place of true natural abundance, and learned how to thrive in the wilderness as a scientist and a single mother. Then, in 1989, industrial aquaculture moved into the region, chasing the whales away. Her fisherman neighbours asked her if she would write letters on their behalf to government explaining the damage the farms were doing to the fisheries, and one thing led to another. Soon Alex had shifted her scientific focus to documenting the infectious diseases and parasites that pour from the ocean farm pens of Atlantic salmon into the migration routes of wild Pacific salmon, and then to proving their disastrous impact on wild salmon and the entire ecosystem of the coast. Alex stood against the farms, first representing her community, then alone, and at last as part of an uprising that built around her as ancient Indigenous governance resisted a province and a country that wouldn't obey their own court rulings. She has used her science, many acts of protest and the legal system in her unrelenting efforts to save wild salmon and ultimately the whales--a story that reveals her own doggedness and bravery but also shines a bright light on the ways other humans doggedly resist the truth. Here, she brilliantly calls those humans to account for the sake of us all.
JAMES BEARD AWARD WINNER IACP Cookbook Award finalist In the face of apocalyptic climate change, a former fisherman shares a bold and hopeful new vision for saving the planet: farming the ocean. Here Bren Smith—pioneer of regenerative ocean agriculture—introduces the world to a groundbreaking solution to the global climate crisis. A genre-defining “climate memoir,” Eat Like a Fish interweaves Smith’s own life—from sailing the high seas aboard commercial fishing trawlers to developing new forms of ocean farming to surfing the frontiers of the food movement—with actionable food policy and practical advice on ocean farming. Written with the humor and swagger of a fisherman telling a late-night tale, it is a powerful story of environmental renewal, and a must-read guide to saving our oceans, feeding the world, and—by creating new jobs up and down the coasts—putting working class Americans back to work.
Economics of Aquaculture Feeding Practices in Selected Asian Countries by Mohammad R. Hasan Pdf
After agreeing on the methodology and outline of the country reports, the authors of the case studies, for each feeding strategy and farming system, analyzed demographic factors (including age and marital status, education and ownership structure), physical characteristics (average number of ponds and average pond size), and other input features (stocking strategies, feeding practices, types of feed, frequency and intensity of feeding and labour utilization). The case studies also identified the principal input costs, assessed the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, break-even prices and production and returns on capital for each feeding strategy. Problem areas were identified for the different farming systems.

Aquaculture Sourcebook by Edwin S. Iversen,K.K. Hale Pdf
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.
Public, Animal, and Environmental Aquaculture Health Issues by Michael L. Jahncke Pdf
The first volume to thoroughly address health concerns in the aquaculture industry Aquaculture-farming aquatic plants and organisms-is one of the fastest growing sectors of agriculture, yet attention to aquaculture health concerns has not been equal to the rate of the industry's expansion. Public, Animal, and Environmental Aquaculture Health Issues serves as a valuable guide to new enterprises, regulatory agencies, and government agencies that are concerned with safe, controlled aquaculture development. The majority of aquaculture products pose no significant health risk; however, like traditional farming operations, aquaculture has associated risks to employees, animals, the environment, and the consumer. This book addresses potential unanticipated risks from the perspectives of both industrialized and nonindustrialized countries, as well as how to mitigate these risks. Chapters include: * Status of World Fisheries and the Role of Aquaculture * Aquaculture Associated Public, Animal, and Environmental Health Issues in Nonindustrialized and Industrialized Countries * Hazard Analysis Critical Control Point and Aquaculture * Aquaculture and International Trade Regulations * Future Considerations of Global Aquaculture Aquaculture business owners, managers, producers, manufacturers, research and academic scientists, government officials, consultants, and food safety specialists will find Public, Animal, and Environmental Aquaculture Health Issues to be a valuable addition to their professional libraries.
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.
