Abstract:

The present study  “Effect of Aqueous and dietary minerals supplementation on growth and survival of Litopenaeus vannamei in low salinity  water” was conducted in the Krishi Vigyan Kendra, Kampasagar, Nalgonda of Professor Jayashankar Telangana state  Agriculture University. L. vannamei culture in inland low salinity water in currently being practiced various parts of the country. These environments are often deficient in key ions essential for normal physiological function of shrimp, which resulted in reduced growth and mortalities. In the present study it has been evaluated to identify the efficient source mineral supplementation for L. vannamei in low salinity waters. Aqueous and dietary mineral supplementations were tested for the efficiency on survival and growth of L. vannamei in low salinity water. Experiments were conducted at 3 ppt salinity bore well water for throughout the period of 7 weeks. Dietary mineral supplementation source was proved to be the best option for mineral supply for L.vannamei in low salinity water culture. In the dietary mineral supplementation treatments highest growth performance of 3.92g and survival (80%) were recorded for potassium (K+10g and Na+ 20g per kg diet) supplementation. FCR lowest is recorded in potassium dietary mineral supplementation treatment. Highest growth performance in vannamei was observed for magnesium (Mg2+ 80mg l-1) addition to that water among all aqueous mineral supplementation treatment. The highest survival of 70% was recorded for potassium (30mg l-1) treatment among all aqueous mineral supplementation treatment. All the aqueous and dietary mineral supplementation treatments indicated highest growth and survival than control treatment.
