A preliminary study was conducted to evaluate the effect of dietary propolis extract supplementation on African catfish, Clarias gariepinus growth performance, survival rate and body composition. The African catfish (mean body weight 0.45±0.05 g) were fed with experimental diets prepared by using propolis extract supplementation (0, 5 and 10 g kg-1) for 90 days. The weight gain (12.93±0.48 g), FCR (1.39±0.05) and PER (1.44±0.05) were observed higher in catfish fed with 5 g kg-1 propolis extract than fed with 10 g kg-1 propolis extract significantly (P<0.05) but no statistical difference was found with the control group fish (P>0.05). Whole-body crude protein was significantly higher in catfish fed with 5 g kg-1 propolis extract, than in those fed with control and 10 g kg-1 propolis extract (P<0.05). Based on the results of the present study, it is suggested that feeding fish with 5 g kg-1 of propolis extracts for 90 days has no adverse effect on survival and enhanced the better weight gain and protein in the composition of the African catfish.
