• Sommario/riassunto: Aquaculture Ecosystems contains a thorough and exciting synthesis of current information on aquaculture practices and substantial discussion of the way forward in transforming the aquaculture industry by improving its sustainability. This important book includes discussion of all the current major issues relating to aquaculture practices in relation to the ecology of their situations, environmental concerns, and details of how sustainability can be improved. Efforts have been made to include chapters that go beyond the stage of debate on old topics, providing conclusions to provide leads for
