This edition includes a chapter on water quality plus the latest findings in yabby farming. It provides a grounding in the basic principles of aquaculture and reflects the considerable advances in aquaculture technology over the last few years. Here is the basic information on the yabby, its habitat, its health and nutrition requirements. The book covers pond management, production systems, equipment, harvesting, post-harvest handling, and marketing of the end product. It includes sections on the farming of those other freshwater crayfish, the redclaw and the marron, and contains a number of useful appendices. Author John Mosig shares his experience of nearly 20 years, giving budding yabby farmers an insight into how they can run a yabby venture while developing their own aquaculture skills and gaining experience in fish husbandry. Practising crayfish farmers might find out how they too can do some things better.
