Abstract
Altogether, two hundred seventy fingerlings of C. carpio (4.71±0.012g) were randomly distributed in six treated groups in triplicates form. Carp were fed with basal diet containing 40% protein supplemented with ethanol extract of lapsi fruit at 0, 0.1, 0.2, 0.4, 0.8 and 1.6 g kg -1 @ 3% of their body weight twice daily for 70 days. Cent per cent survival rate were observed in T3 and T4 diet fed group while the survival rate was 91.11% in T1 control diet fed group. For growth profile final weight gain, final length gain, specific growth rate and feed conversion ratio were measured. Similarly, proximate analyses of all the treated diets were assayed with SGOT, SGPT and ALP. There was significant (p<0.05) differences in weight gain, length gain and specific growth rate in treated diet fed group to that of control diet fed group. Carp fed with T4 diet (0.4%) showed higher length gain, weight gain and SGR as compared to others while higher decreasing trend were observed in feed conversion ratio (FCR) of T4 diet. Growth rate was 87.89% higher in T4 diet fed group while it was only 53.68% in control diet fed group. Significant decreasing trend were observed in SGOT, SGPT and ALP in all the treated diet fed group but the lowest decreasing trend were in T4 diet fed group. It can be concluded that a minimum amount of 0.4 g lapsi fruit extracts kg^-1 is sufficient to be added in diet for good serum enzymes levels and growth performances of common carp.
