Role of Minerals Supplementation on Growth and Survival of Litopenaeus vannamei in Low Salinity Water

Abstract

In the present study dietary mineral supplementations were tested for the efficiency on survival and growth of L. vannamei in low salinity water. Experiment was conducted at 3ppt salinity bore well water for a period of 7 weeks. Dietary mineral supplementation source proved to be the best option for mineral supply for L. vannamei in low salinity culture. In the dietary mineral supplementation treatments highest growth performance of 3.92 g in potassium and survival (80%) was recorded for potassium and sodium (K+10 g and Na+ 20 g per kg diet) supplementation. Lowest FCR was recorded in potassium incorporated fed among all the treatments. All the dietary mineral supplementation treatments indicated highest growth and survival than control.
