The metazoan parasites of 403 specimens of the southern ray's breamBrama australisfrom three localities in southern Chile (Lebu 36° 70′ S; 73° 40′ W, Calbuco 41° 50′ S; 73° 08′ W and Punta Arenas 53° 10′ S; 70° 50′ W) were recorded. More than 23 400 parasite specimens belonging to 12 taxa were registered. Metazoan parasites were dominated by the copepodHatschekia conifera, constituting 97% of the total number of parasites; the larval cestodeHepatoxylon trichiuriwas the second most important parasite (2·1% of the total number of parasites). The remaining 10 species constituted <1% of the metazoan parasites. Parasitological evidence, based on univariate and multivariate analysis, does not support the existence of discrete stocks in the studied zone.
