Opis

Aquaculture in the Ecosystem An Introduction The growth of Aquaculture and its future role as a food supplier to human society has environmental, social and economic limitations, affecting marine ecosystems and socio-economic scales from local to global. These are close links with human health requirements and societal needs for various goods and services provided by marine ecosystems. This book shows this broad spectrum of dependencies of the future growth of aquaculture and highlights both relevant problems and expectations. Compensating for stagnant wild capture fisheries and the increasing demand for marine products, marine aquaculture is one of the fastest growing industries in the world, comparable to the computer technology industry (Chapters 9 and 10). The demand for marine products is controlled by a complexity of factors in our society, not least the increasing human population and the increasing global affluence that allows the consumer to buy higher priced marine products such as salmon, tuna and shellfish (Chapter 9). The populations of several of these top-carnivore species are seriously compromised and it will be impossible in the future to maintain wild c- tures at the level of consumer demand. In less affluent areas including SE Asia and Africa, aquaculture for both domestic consumption and export has major nutritional and economic benefits. The production of fish in aquaculture is thus expected to increase under the assumption that the bottlenecks for expansion can be overcome (Chapter 10)."

Recenzje

From the reviews:

"Marine aquaculture is one of the fastest growing industries globally. ... Holmer ... and colleagues have compiled papers that describe the impact of fish waste on ecosystems, monitoring of impacts, competing coastal land demands, genetic pollution of wild stocks, inadvertent release of nonnative species, and challenges to sustainable feeding. ... Summing Up: Recommended. All readers." (J. Burger, Choice, Vol. 46 (2), October, 2008)

The global expansion of aquaculture production and its future role as a food supplier to human society has environmental, social and economic limitations, affecting marine ecosystems and socio-economic scales from local to global. The expansion is closely linked with human health requirements and societal needs for various goods and services provided by marine ecosystems. This book provides a scientific forecast of the development in aquaculture with a focus on the environmental, technological, social and economic constraints that need to be resolved to ensure sustainable development of the industry and allow the industry to be able to feed healthy seafood products to the future generations. The chapters included discuss the most critical bottlenecks of the development encompassing subjects of understanding the environmental impacts, the current state-of-art in monitoring programs and in coastal zone management, the important interactions between wild and cultured organisms including release of non-native species into the wild, the current trends within the development of aquafeeds along with human health aspects as well as the political, socio-economic and economic trends within the industry including a chapter on approaches taken by Non Governmental Organisations (NGOs) to aquaculture. Finally the last chapter provides different future scenarios of the industry based on the identified bottlenecks.
