This study was carried out to investigate the effect of the use of additional foods and feed ratios for the herbella iden Ctenopharyngodon on some growth indicators in plastic ponds. Fish were distributed on the three treatments. The ratio of the three treatments was (T1) 5% of the body weight and the second treatment (T2) 8% of the body weight and the third treatment (T3) 10% of the body weight, One tub is 70 liters of water. The fish of the three treatments were fed on the same locally produced commercial diet. The study showed that the best growth indicators were obtained in the second treatment, which was fed to a feeding ratio of 8% Fish weight We conclude that feed and feed additives can be used to feed carp fish for their good weight gain by feeding on additional foods.
