Abstract

The effect of tilapia diet supplemented with activated charcoal (AC) on growth performance and intestinal morphology of Nile Tilapia was examined. The fish were divided into four groups: a control group and three AC-supplementation groups (1%, 2% and 3% of AC in diet), and fed approximately 3% of body weight twice a day for 30 days. Growth performance and intestinal villus height were measured. Results revealed that the 2% AC-supplemented diet group was significantly (P<0.05) better in terms of percentage weight gain, specific growth rate (SGR) and feed conversion ratio (FCR), among the experimental groups. The foregut and midgut villus height of the 3% and 2% AC-supplemented diet groups was similar, but was significantly higher than the control group (P<0.05). Consequently, the supplementation of diet with 2% AC was found to be the most suitable for improving the growth performance and intestinal morphology in tilapia.
