Fanners employing crude human chorionic gonadotropin (Sumach, Infar India Ltd.) for inducing breeding of major carps, in India have claimed that it also promotes growth. The present study was undertaken in order to confirm this and its potential statics pure HCG (Sigma Chemicals Ltd), wherein two experiments were conducted in a recirculatory system. In the first experiment of 84 days duration, 10 mg/kg diet Sumach induced significantly higher growth, but not 20mg/kg diet. Both doses of pure HCG tried (1 and 2 mg/kg diet) were ineffective. In the second experiment, growth produced by 5 mg/kg diet pure HCG and 10 mg/kg diet Sumach were comparable and significantly higher than the rest after 42 days, indicating higher potential of pure HCG. The findings are significant as they reveal that a protein hormone like HCG is capable of growth promotion in carp when administered orally
