Types of Aquaculture

Extensive - Usually in earthen ponds, green water system where fish are not fed regularly

Semi-intensive - Ponds (earthen or otherwise green water system, fish fed incomplete ration of feed

Intensive - Tank culture, Fish fed complete ration, clear water system, heavy aeration, circulation and filtration.

Monoculture - Rearing of one species

Polyculture - Rearing of multiple aquatic species within the same body of water

Integrated culture - rearing multiple species, aquatic and semi aquatic within the same enclosure with synergistic effects.
