The estimated production of prawn-cum-paddy culture varies from 400 to 1200 kg/ha for six months period. F. indicus forms about 36%–43% of the total yield of shrimp which can go up to 400–900 kg/ha/yr. Extensive culture can be made more productive by construction of artificial ponds, use of aeration and supplementing with artificial diet.
