The aim of this work was to observe the growth rate and survival of Piaractus mesopotamicus (pacu) and Colossoma macropomum (tambaqui) cultured in the laboratory and fed with natural plankton (phytoplankton and zooplankton), during 40 days. The larvae were 4 days old. They were reared in continuous flow aquaria and fed with natural plankton, daily. The growth rates for each species was relatively similar. The maximum lenght for C. macropomum was 1.8 cm and 1.7 cm for P. mesopotamicus. In relation to fresh weight, a value of 58.1 mg was found for C. macropomum and 57.7 mg for P. mesopotamicus. The final values of dry weight were 13.1 mg and 7.4 mg, respectively.Downloads
