Response of Penaeus vannamei to Dietary Calcium, Phosphorus and Calcium: Phosphorus Ratio Academic Article uri icon


  • Two experiments, consisting of 7 d conditioning periods and 33 d feeding trials, were conducted to evaluate the response of juvenile Penaeus vannamei to dietary calcium, phosphorus and the effects of the calcium to phosphorus ratio on growth and tissue mineralization. In both experiments, the main effects, calcium and phosphorus, and their interaction significantly affected growth and survival of the shrimp. In the absence of supplemental calcium, the basal diet containing 0.35% phosphorus was adequate to maintain good growth and survival of shrimp. In the presence of replete phosphorus, supplementation of 1.0 and 2.0% calcium to the diet depressed survival and did not appear to increase the nutritive value of the diet, indicating that a dietary calcium supplement is not required under these conditions. In the presence of 1.0 and 2.0% supplemental calcium, supplementation of 0.51.0% phosphorus and 1.02.0% phosphorus, respectively, were required to maintain normal growth of the shrimp. At high levels of calcium supplementation, poor growth was observed at the levels of phosphorus supplementation evaluated. Although the calcium and phosphorus content of the hepatopancreas and the carapace responded to dietary supplementation, there was no clear correlation of tissue mineralization to shrimp growth.
