【 摘 要 】

The aim of this work was to study the possible utilization of Thermocyclops decipiens as indicator of the trophic degree and water quality of some watersheds of the state of Minas Gerais. From the beginning of the decade of 90, T. decipiens was recorded in several water collections of the state, including the basins of the rivers Paranaíba, São Francisco, Doce and Grande, within environments mainly of meso and eutrophics characteristics. Of the 28 places of occurrence of the species and according to the water quality index (WQI) used by Environmental Foundation of Minas Gerais (FEAM), 7 of these environments presented WQI good, 16 medium, 4 bad and one very bad. This classification corroborated the hypothesis that T. decipiens could be used as indicator species of eutrophic environments and of low water quality thus constituting an important tool for the biomonitoring of aquatic ecosystems.
