Aquaculture worldwide

Aquaculture is defined and global production statistics are given in comparison with the total catch of wild fish. Special emphasis is placed upon the considerable diversity of aquaculture in terms of the various species farmed, the husbandry systems adopted, the varying degrees of control exercised over the life cycle, and the existence of culture-based fisheries, etc. Current trends in aquaculture include more intensive production methods and a better understanding of dietary needs, together with stock improvements stemming from research into fish genetics, health and rearing novel aquatic species.
