A number of aquaculture practices are used world-wide in three types of environment (freshwater, brackishwater, and marine) for a great variety of culture organisms. Freshwater aquaculture is carried out either in fish ponds, fish pens, fish cages or, on a limited scale, in rice paddies. Brackishwater aquaculture is done mainly in fish ponds located in coastal areas. Marine culture employs either fish cages or substrates for molluscs and seaweeds such as stakes, ropes, and rafts. (Summarized information on major culture systems and practices used for the principal culture organisms on a regional basis, is given in Table 6.)
Culture systems range from extensive to intensive depending on the stocking density of the culture organisms, the level of inputs, and the degree of management. In countries where government priority is directed toward increased fish production from aquaculture to help meet domestic demand, either as a result of the lack of access to large waterbodies (e.g., Nepal, Central African Republic) or the over-exploitation of marine or inland fisheries (e.g., Thailand, Zambia), aquaculture practices are almost exclusively oriented toward production for domestic consumption (UNDP/NORAD/FAO, 1987).
These practices include:
(i) freshwater pond culture;
(ii) rice-fish culture or integrated fish farming;
(iii) brackishwater finfish culture;
(iv) mariculture involving extensive culture and producing fish/shellfish (e.g., oysters, mussels, cockles) which are sold in rural and urban markets at relatively low prices.

Pisiculture is the process of cultivation of fishes. It involves raising of fishes for commercial purposes in artificial tanks or natural lakes and areas for the main purpose of food which is achieved from them. It is the basic principle form of aquaculture and all other falls under marine aquatic culture. Pisciculture has a vital role in augmenting food production as the world demand for fish products is increasing steadily in the world.
