IMTA works by creating a closed-loop system where the by-products such as excess nutrients and organic waste from fish farming, are utilized by other species such as shellfish and seaweed. This process can decrease water pollution, minimize the need for chemical fertilizers, and improve overall ecosystem health.
Integrated farming (IF), integrated production, or integrated farm management is a whole farm management system which aims to deliver more sustainable agriculture without compromising the quality or quantity of agricultural products. Integrated farming combines modern tools and technologies with traditional practices according to a given site ...
Particular kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, pisciculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture , both of which integrate fish farming and aquatic plant farming.
The system was recognized by the FAO in 2002 as one of the first Globally Important Agricultural Heritage Systems. The benefits of rice-fish systems include increased rice yield, the production of an additional (fish) crop on the same land, diversification of farm production, increased food security, and reduced need for inputs of fertilizer ...
Subsets of it include (offshore mariculture), fish farms built on littoral waters (inshore mariculture), or in artificial tanks, ponds or raceways which are filled with seawater (onshore mariculture). An example of the latter is the farming of plankton and seaweed, shellfish like shrimp or oysters, and marine finfish, in saltwater ponds
Traditionally, shrimp farming ranges from intensive to extensive systems. 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.
In a well designed system, the existing water in the raceway is largely replaced by new water when the same volume of new water enters the raceway. Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low. For example, if trout are stocked at 20 kilograms per cubic metre ...
Modern fisheries management is often referred to as a governmental system of appropriate environmental management rules based on defined objectives and a mix of management means to implement the rules, which are put in place by a system of monitoring control and surveillance. An ecosystem approach to fisheries management has started to become a ...
