Rapid growth is of paramount importance for young fish. Therefore, studies focused on the rate of growth in freshwater and marine fish species were done with a major the objective to study the effects of antraquinone extract from rheum palmatum on the growth of Rutilus frisii kutum. Kutum fingerlings were divided randomly into four groups: a control group fed on basal diet, three treatment groups fed on a basal diet supplemented with 0.5%, 1% and 2% anthraquinone extract respectively. The growth was monitored after 8 weeks. FCR and SGR were higher in supplemented groups with antraquinone extract. The group supplemented with 0.5%-2.0% antraquinone extract from Rheum palmatum significantly had increased in growth. It was shown that that 0.5%-2% anthraquinone extract from Rheum palmatum that was added to basal diet promoted growth of fish.
