Pond carrying capacity is largely determined by management practices. Earlier work on semiintensive culture of Nile tilapia (Oreochromis niloticus) using manure or inorganic fertilizers indicated that carrying capacity might reach 2,000 to 3,000 kg/ha (Diana et al. 1991a, b; Knud-Hansen et al. 1991). As stocking density is increased in fertilized ponds, carrying capacity remains largely the sam...
