Abstract

The possibility of inclusion of hexanic, acetonic and methanolic extracts of Turbinaria ornata as aqua feed additive was assessed by evaluating its growth promoting potential on Macrobrachium rosenbergii post-larvae (PL). The each solvent extract of T. ornata was incorporated at 0.5, 1.0, and 1.5% with basal diet prepared using fish meal, groundnut oilcake, soy bean meal, wheat bran, sun flavor oil, tapioca flour and egg albumin, and fed to M. rosenbergii PL for 90 days. On the final day, the survival and nutritional indices including weight gain, specific growth rate, food conversion ratio and protein efficiency ratio, the contents of basic biochemical constituents (total protein, carbohydrate, lipid, amino acid and fatty acid), and activities of digestive enzymes (protease, amylase and lipase) were found to be improved significantly (P < 0.05). Among the three solvents, methanolic extract of T. ornata incorporated feed, particularly at 1.5% produced the best (P < 0.05) performance in all these parameters. The activities of antioxidant (superoxide dismutase and catalase) and metabolic (glutamate oxaloacetate transaminase and glutamate pyruvate transaminase) enzymes, and the status of lipid peroxidation were found to be insignificantly altered (P > 0.05). Therefore, T. ornata extract was not toxic to M. rosenbergii PL. Thus, it is recommended as a feed additive for sustainable aquaculture development.
