Prawn culture

Raising, processing and marketing of prawns/shrimps as a source of protein food. The most widely cultured fast growing species in the globe as well as in Bangladesh are the giant black tiger shrimp Penaeus monodon and the giant prawn Macrobrachium rosenbergii. Their culture techniques are traditional, extensive, improved extensive, semi-intensive, intensive and super intensive, named mainly based on the stocking density of post larvae (pl) and management techniques of the culture ponds. Both monoculture, polyculture and integrated culture with paddy (rotational and concurrent) and with fin fish (mullets, carps and tilapia) are the common systems practiced. But shrimp culture starts in saline water and prawn culture mainly in freshwater though they all need saline water for hatching of eggs in the hatchery.
