The continuing rapid increases in aquaculture production world-wide raises fears of further environmental degradation of the aquatic environment. The 2nd edition of this well-received book brings together and discusses the available information on the environmental aspects of various aquaculture systems, providing a valuable aid to the preparation of environmental impact assessments of aquaculture projects and shows how potential environmental problems can be reduced or mitigated by sound management.
this second edition of this benchmark book reflects the enormous developments that have occured in aquaculture in the intervening decade or so... this timely book addresses those problems and offers a number of practical solutions to them. It is practical, well researched and well presented Work Boat World, December 2007 The new edition of Aquaculture: Principles and Practices is a useful addition to the literature, and is suitable as a textbook for college and university courses Aquaculture Int (2007) 15:505--506
