Reviews

“This is the third edition of a book first published seven years ago. The book and cage aquaculture have come a long way in that time.
Doctor Beveridge’s book is quite simply the key text book for the fast growing cage aquaculture industry. The latest edition describes all the most recent developments in this increasingly important and very fast developing sector of the marine industry”
Review appeared in:
Ausmarine (incorporating Professional Fisherman),and Fishing Boat World, both 2006
"This review of fish culture in cages thoroughly discusses water-based systems of aquaculture. The author characterizes and elaborates advantages and disadvantages relative to land-based systems such as ponds and raceways... The book is logically organized and clearly written."
Journal of Environmental Quality, 2006
