IMS aquaculture is similar to extensive farming in that it doesn't depend on chemical inputs, formulated feed and shrimp larvae but instead relies on natural feed and natural shrimp recruitment from the exchange of tidal water. [2] [4] [8] Silvoaquaculture, is a manageable alternative for small-scale farmers who lack access to financial support.
Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
The United Nations writes that "intensification of animal production was seen as a way of providing food security." [24] In 1966, the United States, United Kingdom and other industrialized nations, commenced factory farming of beef and dairy cattle and domestic pigs. [9] As a result, farming became concentrated on fewer larger farms.
Fish chosen for extensive aquaculture are very hardy and often do well in high densities. Seaweed, prawns, mussels, carp, tilapia, tuna and salmon are the most prominent forms of extensive aqua cultured seafood. Extensive aquaculture facilities have negative impacts on the environment as well.
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [ 2 ]
Marine shrimp farming is an aquaculture business for the cultivation of marine shrimp or prawns [Note 1] for human consumption. Although traditional shrimp farming has been carried out in Asia for centuries, large-scale commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the United States, Japan and Western Europe.
Aquaculture Solutions established and operated a commercial aquaponics farm in South Africa for 9 years, supplying vegetable crops and fish to local supermarkets and delis. The farm utilised deep water culture as well as the ebb and flow techniques to enable the production of lettuce and cucumber which were the primary crops.
