Abstract

The current research work was undertaken to evaluate the impact of dietary lycopene supplementation in enhancing the growth performance of fresh water fish Channa punctata. The experimental fishes were fed diets containing five different lycopene concentrations (10, 12, 14, 16 and 18mg/ kg) over an eight-week period. Growth performance was evaluated across seven treatment groups including controls. The study resulted in significant gain in weight (6.64±0.08g to 10.11±0.12g) and length (0.8±0.05cm to 3.03±0.33cm) among fishes treated with increasing concentrations of lycopene compared to control. Lycopene concentration of 14mg/ kg displayed the minimum feed conversion ratio (FCR) value of 1.10±0.06. The lycopene supplementation of 14mg/ kg exhibited the maximum (1.98±0.08%. day-1) specific growth rate (SGR). However, diets supplemented with 16mg/ kg and 18mg/ kg of lycopene showed a decline in SGR. A second order polynomial fit analysis between dietary lycopene level and SGR showed the optimal dietary concentration of lycopene for maximum growth (14.29mg/ kg). These findings suggest lycopene as a promising natural growth promoter in aquaculture feed formulations for sustainable fish culture activities as alternate to synthetic chemical growth promoters.
