Abstract

The aim of this study was to evaluate the richness and the abundance and biomass of the zooplankton community of different fish farming systems in the Rio de Janeiro state. In the first stage of the study, 30 fish ponds were analyzed and ten of these were selected for the second stage. The total number of taxa found in the samples was 127: 71 rotifers, 13 cladocerans, seven copepods and 26 protozoans. About the abundance, rotifers predominated in the mostly systems and, in the second stage, the copepods showed higher abundance. Although the rotifers have highlighted the richness and abundance, biomass values were in the majority of low carbon systems (µg C L-1) compared to biomass values presented by cladocerans and copepods in the entire study. The species Brachionus calyciflorus and Moina micrura were associated with higher nitrogenous compounds concentration, and were suggested as indicators of eutrophication of these studied systems.
