Habitat for organisms in ecosystems include attributes to the ecological significance and resulting from the interactions between its physical, chemical and biological components. In fishponds, one of the important features is the community of the microzooplankton that é key component of marine food webs and food chain in freshwater. An experiment was carried out in an area for fish farming, located in Assis Brasil Village, municipality of Cruzeiro do Sul, State of Acre, aimed to observe the dynamics of fish farming tanks, and the composition and microzooplankton abundance, submitted to two treatments, commercial feed (ad libitum) and tabulated feed. The results showed that environments severely eutrophicated are characterized by high values of phosphorus and nitrogen, and dominance of species of Rotifera, throughout the study. On this basis, it was concluded that researches of this nature contributes for determining the water quality, particularly using potential bioindicator species, that grow excessively in these environments.
