520 Aquaculture growth worldwide involves the expansion of cultivated areas, a higher density of aquaculture installations and farmed individuals, and greater use of feed resources produced outside the immediate culture area. To ensure that such development of the sector does not carry negative impacts on the environment and on parts of society due to weak regulation or poor management, an ecosystem approach for aquaculture (EAA) is encouraged. These proceedings consider aspects relevant for an ecosystem-based management in aquaculture. The document also includes two comprehensive reviews covering the status of brackish, marine and freshwater aquaculture within an ecosystem approach perspective.--Publisher's description
