Abstract
Prawns (Macrobrachium rosenbergii) were cultured in 0.04-ha ponds alone at densities of 25,000 and 50,000/ha, and at 25,000/ha with channel catfish fry (Ictalurus punctatus) at 150,000/ha. Catfish were also cultured alone at the same density. Mean survival was poor (prawns, 14-22%; catfish, 14-18%) and production was low (prawns, 90-270 kg/ha; catfish, 640 - 770kg/ha) after 140 days for prawns and 110 days for catfish. Survival and production values were lowest for prawns in the polyculture ponds (P < 0.05). Resident crayfish (Procambarus clarkii and P. acutus acutus) were harvested from all ponds (490 - 550 kg/ha).This publication has 0 references indexed in Scilit:
