ResumoABSTRACT A population of the Asiatic clam, Corbicula fluminea, and eight species of cohabiting unionid mollusks were examined for the presence of the oligochaete, Chaetogaster limnaei. The mollusks were collected in navigation Pool 19, upper Mississippi River. Infestation of C. limnaei in the Asiatic clam was significantly greater than in unionids. A decline in occurrence and abundance of C. limnaei infesting the Asiatic clam was found in the winter when the Asiatic clam population also declined. Of the unionid mollusks, Leptodea fragilis had the highest rate of infestation and the highest number of C. fluminea per individual.
