This study was conducted to evaluate the effects of dietary lapsi Choerospondias axillaris (Roxb.) on survival, growth and protein profile of Cyprinus carpio (L) fingerlings. Six practical diets were formulated to contain 0.0 (control), 100, 200, 400, 800, and 1600 mg ethanol extract of lapsi fruits equivalent kg (-1) diet. Each diet was fed to triplicate groups of fingerlings of C. carpio (4.71± 0.012 g) in 100-L glass aquaria as T1, T2, T3, T4, T5 and T6 @ 3% of their body weight twice daily for 70 days. The results showed statistically significant (P<0.05) increased in weight gain, SGR, total protein and globulin which may be considered as a sign of improvement in immune system. It may be due to presence of antioxidant properties (vitamin C) in lapsi fruit extract which act as an antioxidant. Finally, it has been concluded that a minimum amount of 0.4 g lapsi fruit extracts kg-1 is sufficient to be added in diet for increment of good growth and serum protein in common carp.
