Abstract

Six diets containing different levels of carbohydrate namely 0, 5,10,15,20 and 25% were tested on Qarias
batrachus fry of 0.9 to 1.14 g body weight for a period of 20 weeks. The levels of protein and lipids were
maintained at an average of 40% and 9.3% respectively for all the diets. The growth, food conversion
efficiency and protein efficiency ratio were compared at the end of the experiment. The diets containing 15%
and 29% carbohydrate produced significantly better growth than the diets containing 0,5,10 and 25% carbohydrate.
No significant difference weight-gains was observed among the fish fed on diets containing
0, 5,10 and 25% as well as between 15 and 20% carbohydrate. A food efficiency of 16.4 and 14.1% and,
protein efficiency ratio of 0.41 and 0.34 obtained by fish fed on 15 and 20% carbohydrates in diets
respectively were also superior to the other four groups. From this experiment 15 or 20% carbohydrates
appeared optimal in the diets of C. batrachus fry.
