Summary

Since the first edition of this book, 17 years ago, aquaculture has consolidated its position as an important means of producing food and as a contributor to global food security. Cage aquaculture too has continued to expand apace. The third edition of this important, useful and well-received book maintains the original aim of providing a thorough synthesis of information on cages and cage aquaculture practices with data and examples encompassing all major world regions.Fully updated, the book's comprehensive contents include details of the origin and principles of cage aquaculture and an overview of its current position. Contents of the chapters following include key information on cage design and construction, site selection, environmental impacts and environmental capacity, management, and potential problems in cage aquaculture systems. A comprehensive reference list and index are included to help readers.The volume is essential reading for all personnel involved in fish and shellfish farms that use cages, and for all those embarking on a career in aquaculture. Cage manufacturers and others supplying the aquaculture trade will find much of commercial use within the book. All those involved in aquaculture research and equipment design should have a copy of this most useful book. All libraries in universities and research establishments where aquaculture, environmental science, aquatic science, fish biology and fisheries are studied and taught should have several copies on their shelves.
