Total aquaculture production in Indonesia in 1994 was 493 000 tons of finfish, 169 000 tons of shellfish, mainly shrimp and 115 000 tons of seaweed with an estimated value of US$ 2 075 million. In 1994, the production of common carp (Cyprinus carpio) was 135 200 tons, from ponds (52 600 tons), cages (28 600 tons) and ricefields (54 000 tons). The potential for aquaculture in Indonesia is large. The mangrove forest area is estimated to be around 4.29 million ha. It is recommended to use only 20 % of the total mangrove area for aquaculture production (830 900 ha). To day only 37 % of this area is used for aquaculture. The most suitable species for brackishwater aquaculture are shrimp and milkfish. The area for mariculture is 81 million ha, with potential production of about 47 million tons of fish, shellfish and seaweed. The total area of freshwaters is 55 million ha. consisting of lakes, dams, rivers, swamps and other water bodies. Potential area for freshwater pond fish culture is estimated to be 338,121 ha., with a production potential of 8-9004 000 tons per year
