AQUACULTURE SYSTEMS RANGE from extensive to intensive depending on the stocking density of the culture organisms, the level of inputs and the degree of farm management.In the Asia-Pacific region, major culture species include diverse freshwater and marine species such as high-value shrimps, molluscs, seaweeds, with carps and seaweeds dominating production, mussels and oysters, red seaweeds etc. Major culture practicesinclude fish ponds, fish pens and fish cages, floating rafts, lines and stakes for molluscs and seaweeds, hanging lines for mussels and pearl oysters, offshore cages for salmon, pond culture for shrimps, tilapia, catfish and milkfish and freshwater pensfor crayfish.
