Abstract
The estuary of Bahía Blanca (39° 03′44 ″ S 62° 04′00 ″ W) occupies a large coastal area south of the province of Buenos Aires,
Argentina. This area includes urban centers, several industrial parks and deep-water ports. The parasites sensitivity to pollutants
and environmental disturbances makes many taxa useful indicators of environmental health and anthropogenic impact. In the
present study, the variation in helminth communities of Sympterygia bonapartii was analyzed retrospectively after a period of 18
years. Infra-communities harbored an average of four times more parasites and became less equitable. A gradual increase in organic
matter added to the parameters synergy caused by untreated sewage discharges, seems to have been the most important impact
on helminth communities, altering the abundance, dominance and eveness. The present study proposes fish parasite analysis as a
reliable model to monitor pollution in this ecosystem.
