This book is the most complete, accessible and affordable guide to freshwater aquaculture in Australia, emphasising sustainable use of all resources: whether it be on a small scale in a backyard pond, or in commercial production on broad acres. It includes detailed information from design and construction of ponds to water quality, enhancing production through aeration, filtration and water treatment wetlands, foods and feeding, breeding and propagating aquatic animals and plants, sources of stock and polyculture (mixing fish, crustaceans, other animals, and plants for greater yields).
