Effect of Selected Nutraceuticals on Growth and Metabolism of Penaeus vannamei Juveniles Reared in Inland Saline Water

The objective of this study is to evaluate the individual and combinatorial effects of lipid-utilizing nutraceuticals (L-carnitine, taurine and quercetin) on growth, protein and carbohydrate metabolic enzymes in P. vannamei juveniles reared in ISW of 10 ppt salinity.

A 60-day experiment was conducted to evaluate the individual and combinatorial effects of L-carnitine, taurine and quercetin on the growth and metabolism of P. vannamei juveniles. The shrimps were fed with eight experimental diets, viz. Control, T_C, T_T, T_Q, T_C+Q, T_C+T, T_T+Q and T_C+T+Q to evaluate their effect.

All the nutraceutical-fed groups exhibited significantly higher growth, feed utilization, AST and ALT activities than the control group. Among the nutraceutical fed groups, T_C+T and T_C+T+Q treatment groups exhibited higher growth, AST, ALT and lower LDH and MDH activities than other treatment groups.
