Growth performance, feed utilization and changes in body composition of Colossoma macropomum (Cuvier) juveniles — in the weight range 2 to 200g — fed an artificial high protein diet, have been analysed against feed ration and fish weight. A polynomic equation is developed which permits prediction of growth and radon parameters in this weight range. The results are compared with the values of other cultured common freshwater fish species. Colossoma macropomum must be considered a very fast grower with good feed utilization.
