Resumen:
Abstract The effects of a sewage effluent with notreatment on the mesozooplankton structure and theenvironmental quality were evaluated in the BahíaBlanca Estuary, during June to November 1995. Thehighest values of particulate organic matter, nutrientsand specially phosphate, were observed in the effluentdischarge zone. In addition, taxa richness, mesozooplanktonabundance and Shannon diversity valueswere lower in the sewage discharge area comparedwith the less polluted area. Eurytemora americanaand Acartia tonsa as well as larvae of Balanusglandula, Neohelice granulata and Spionidae werefound in the discharge area with lower densities.These results highlight the importance of sewageeffluent effects on mesozooplankton communityproviding background data to use in other monitoringprogrammes.
