Sumario:The purpose of this work was to evaluate the chemical and bromatological composition of three submerged aquatic plant species originated from mechanical control operations, to later determine the best strategy to discard and/or use the biomass harvested during the mechanical control operations. This study was carried out in the summer and winter of 2001, with the plants being harvested at nine points on Tietê River of the Jupia reservoir. Samples were dried, milled and sent for analysis. Among the three species, the highest concentration of the analyzed elements was observed in plants harvested during the summer with a decrease in concentration being observed in plants harvested in the winter. C. demersum showed the best bromatological concentration with higher rates of crude protein, minerals and digestibility.
