摘要：The effect of dietary Limonia acidissima L. fruit (LF) on the growth and feed utilization was investigated in Cirrhinus mrigala and Cyprinus carpio. Mrigal fingerlings of about 5.30 ± 0.03 g and Carp fingerlings of about 3.50 ± 1.50 g were fed, diets supplemented with three concentrations (1.5 %, 3 %, and 6 %) of herbal diet for 30 and 60 days. Survival, specific growth rate, feed conversion rate, feed efficiency and relative growth rate parameters were significantly different (p 0.05) and higher in experimental groups compared to control. The highest weight gain (17.75 ±0.19; 50.91 ±0.39) and feed conversion ratio (0.92 ±0.01; 0.64 ±0.03) of C. mrigala were observed at 30 and 60 days respectively in 3% herbal diet fed group and lowest in control. In addition, the highest weight gain (18.97 ±0.10; 51.53 ±0.20) and feed conversion ratio (0.56 ±0.007; 0.42 ±0.005) of C. carpio were observed in 3% herbal diet and lowest in control. Protein efficiency ratio and specific growth rate for C. mrigala and C. carpio respectively were higher in fishes fed with 3% herbal diet and lowest in control. The overall difference in parameters between C. mrigala and C. carpio were significant among experimental group than the control (p 0.05). These results reveal that an underutilized fruit of medicinal plant Limonia acidissima L. enhance the growth and metabolic parameters of C. mrigala and C. carpio fingerlings.
