Growth performance, muscle biochemical constituents, amino acid and fatty acid compositions of the giant freshwater prawn, Macrobrachium rosenbergii, fed with herb‐incorporated diet. (29th April 2016) - Muralisankar, T.
Abstract: This study was conducted to evaluate the influence of herbs such as Ocimum sanctum, Phyllanthus amarus and Solanum trilobatum on the freshwater prawn, Macrobrachium rosenbergii, postlarvae (PL). These herbs were powdered and incorporated at 5% with the basal diet separately and in a combination. The M. rosenbergii was fed with these feeds for a period of 90 days. Results indicated that significant ( P < 0.05 ) improvements were observed in the survival, nutritional indices (weight gain, specific growth rate and protein efficiency ratio), proximate muscle biochemical constituents (total protein, amino acid, carbohydrate and lipid), profiles of essential amino acids and fatty acids of prawns fed with herb‐incorporated feeds. Among these herbs supplemented, P . amarus produced significantly ( P < 0.05) better performance followed by S. trilobatum and O. sanctum . However, prawns fed with these herbs combination showed an insignificant ( P > 0.05) improvement in survival and growth performance when compared to individual supplementation. Hence, this study suggests that the herbs ( O. sanctum, P. amarus and S. trilobatum ) can be used as a supplementary feed for a sustainable development of freshwater prawn culture.
