Description

From 1961–1965, there was widespread reclamation for farming and freshwater fish and prawn ponds in Singapore. The Agri-Food & Veterinary Authority of Singapore (AVA) has also developed six Agrotechnology Parks to maximise output from its agricultural land through its Agrotechnology Programme initiated in 1986. Agrotechnology Parks are modern agriculture estates developed with the necessary infrastructure for farming. Out of the six Agrotechnology Parks, four of them houses fish and prawn farms. These are located in Lim Chu Kang, Murai, Sungei Tengah and Loyang. As of September 2010, AVA has registered 75 aquarium fish farms taking up a total area of 174 ha, and 5 food-fish and prawn farms occupying a total area of 28 ha, within its Agrotechnology Parks.

Prawn ponds
Traditional prawn ponds are created by digging a shallow pond in the mangroves and building embankments around it. A sluice gate is also constructed between the pond and the main water source to allow for water exchange.  Modern-day farming methods involves raising prawns in high density polyethylene (HDPE)-lined ponds which are filled with temperature-controlled, recycled water which is 100% treated by reverse osmosis after each cycle. Some coastal fish farms in Singapore also farm prawns in their floating cage nets.

Food-fish farms
Singapore's consumption of fish is estimated to be 100,000 tonnes per year of which about 5% is accounted for by local food-fish aquaculture. This is mainly from coastal fish farms which started in the early 1970s. There are 84 licensed fish farms occupying 46.5 ha of coastal waters. Commercial coastal fish farming in Singapore is mainly the culture of economically important food-fish species as well as prawns in floating cage nets. The basic farm structure is the floating wooden raft with polyethylene cage nets attached it. In the selection of suitable sites for fish farming, availability of sheltered waters and water quality standards that are in line with international standards are considered. Water depth, wave height and tidal velocity are also taken into consideration. Freshwater food-fish farms are also present in Singapore. These farms often make use of ponds and tanks to house the fish and can be situated inland.

Ornamental fish farms
Facilities for the production of ornamental fish are often small compared to major food-fish farms. Fishes are typically raised in small vats and outdoor ponds, usually with indoor facilities as well to house small tanks and aquaria. There is also an increase in the cultivation of ornamental fish in indoor facilities, making use of water filtration technologies and other controlled-environment systems.
