A preliminary study was conducted to evaluate the effect of the Rosemary extract (Rosemaria
officinalis) on growth performance, feed utilization and body composition of the African
catfish (Clarias gariepinus, Burchell, 1822). Fish with an average body weight of 10.59±0.31
g were fed with different concentrations (0, 0.25 and 0.5 %) of Rosemary extract at dietary for
60 days. At the end of experiment, the highest values of weight gain, specific growth rate and
food conversion rate were 17.23±0.08 g, 1.93±0.07 and 1.16±0.06 at 0.5% Rosemary extract
dosage group respectively. The highest survival rates were 100% at 0.25% Rosemary extract
dosage groups. No significant differences were shown in whole body protein and lipid content
among the dietary treatments. These results indicate that treatment of Rosemary extract has
positive effect on growth in African catfish with no apparent effects on health status.
