Summary The reasons for considering culture-based fisheries as an aquaculture practice are presented. The need to develop culture-based fisheries, which are basically a nonconsumptive user of water compared to conventional aquaculture practices such as pond culture, to augment the aquatic food supplies, in the wake of increasing consumption of aquatic food, dwindling catches from the wild, and the decreasing rate of growth of conventional aquaculture is evaluated.

The well-documented culture-based fishery practices of a number of countries are reviewed, and the development of these is traced. It is suggested that successful practices occur in mainland China, where the production from culture-based fishery in reservoirs is estimated to be 1,165,075 tons (from a total area of 1,567,971 ha), approximating 743 kg ha−1 year−1, and which is reputed to have recorded a yearly growth of 52% from 1979 to 1997. General features of culture-based fisheries and factors responsible for increasing yields are discussed, and the importance of such practices to rural communities in developing countries is emphasised. The constraints facing the development of the practices and the importance of overcoming such constraints, especially in the wake of the increasing challenges the conventional aquaculture industry is encountering, are evaluated.
