Response of a Freshwater Fish Exposed to a Single Dose of Biofertilizer

The study was carried out to observe the effect of this biofertilizer (MOC) on the Body Muscle Protein (BMP) of Channa punctatus having average length 15.26±0.52cm and weight 28.85±5.028gm. At sub lethal concentration (0.42g.l-1), fishes were exposed for prolonged period and muscle protein was measured on 0, 7th, 14th, 21th and 28th days respectively. Five fishes were sacrificed after each day of exposure to estimate the amount of protein concentration in the muscle following Folin-phenol reagent method. A significant (p<0.05) increase in BMP was observed with the advance of days treatment. After an initial fall, the rise in the BMP concentration, indicating the experimental fish were suffered initially and ultimately victorious and able to increase the protein level in their body.
