Freshwater prawn farming

Freshwater prawn farming is the breeding and rearing of freshwater prawns in managed systems for food and other uses. It ranges from small-scale ponds to commercial hatchery and grow-out operations.

Macrobrachium rosenbergii: A large Indo-Pacific freshwater prawn widely farmed for food. This species is the principal prawn in commercial freshwater aquaculture.
Freshwater aquaculture: The cultivation of aquatic organisms in inland freshwater environments. Freshwater prawn farming is one form of this broader production system.
Polyculture: The simultaneous cultivation of multiple species in the same production system. Prawns can be raised with fish when species use different resources or habitats.
Aquaculture biosecurity: Measures that prevent the introduction and spread of pathogens in aquatic production. Hatchery and farm movements can spread disease between prawn stocks and sites.
Freshwater prawn hatchery: A facility that hatches prawn eggs and rears larvae into postlarvae for stocking. Hatcheries supply the postlarvae needed to begin pond production.
Brackish water: Water with salinity between that of freshwater and seawater. Prawn larvae commonly need brackish water even though juveniles and adults grow in freshwater.
Rice–prawn farming: An integrated system that raises prawns in rice fields during some or all of the crop cycle. It combines prawn production with rice cultivation on the same land.
Aquaculture disease: Illness in cultured aquatic organisms caused by pathogens or environmental stressors. Disease outbreaks can cause severe losses in prawn ponds and hatcheries.
Prawn larval rearing: The hatchery stage in which prawn larvae develop in controlled water and feeding conditions. Larvae require brackish water before they can be transferred to freshwater grow-out systems.
Prawn molting: The shedding and replacement of an arthropod's exoskeleton as it grows. Molting makes prawns vulnerable to injury and cannibalism in crowded culture conditions.
