Effect of exogenous carbohydrases on growth and survival of catla fry


Author(s): VR Patil, AS Pawase, DI Pathan, RA Pawar, SS Dey and S Swain

Abstract: Catla, Gebelion catla is one of the most important Indian major carp species that involves supplementary feeding comprising a mixture of rice bran and groundnut oil cake. Since, the plant origin feed sources are not utilized to the fullest extent by the fishes, inclusion of enzymes in fish diets has been proved to be an effective method to improve the feed digestibility. In the present study, some of the exogenous enzymes such as cellulase, hemicellulase and alpha-amylase each at 0.5. 1 and 1.5% level were incorporated in the diets of catla fry. The experiment was carried out in circular plastic containers of 125 L capacity with twelve treatments and two replicates for a period of 90 days. The catla fry were grown to 35.8 – 47.9 mm in length and 5.53 –4.84 g in weight from the initial length range of 17 – 19 mm and weight range of 0.37 – 0.45 g. Results showed the maximum length, weight gain, specific growth rate and survival in the treatment incorporated with mixture of exogenous enzymes each at 0.5 g 100 g-1 level in the catla fry diet.
