Influence of Ethanolic Extract of Phyllanthus amarus on the Growth of the Prawn Macrobrachium rosenbergii Post-Larvae

The ethanolic extract of Phyllanthus amarus incorporated with artificial feed was found to produce better survival, growth, nutritional indices (weight gain and specific growth rate), activities of digestive enzymes (protease, amylase and lipase), and concentrations of basic biochemical constituents (total protein, amino acid, carbohydrate, and lipid) in M. rosenbergii post larvae when compared with control. The FCR was found to decrease in test prawns, which reflects the better quality of the feed offered. This study suggests that P. amurus have the potency to enhance the general health of test prawn. Thus, this herb is recommended as a feed additive for sustainable culture of Macrobrachium
