This study presents new records of geographical distribution of macroparasites of the marine Odontesthes nigricans (Richardson, 1848) (89 wild specimens),and of the freshwater silversides, Odontesthes bonariensis(Valenciennes, 1835)(43 wild and 108 cultured specimens)and Odontesthes hatcheri (Eigenmann, 1909) (183 wild specimens), from Argentina. These data represent the record of 12 parasite taxa for O. nigricans, 8 for O. bonariensis, and 19 for O. hatcheri, which include digeneans, monogeneans, cestodes, nematodes, acantocephalans, mollusks, copepods, and branchiurans. For cultured O. bonariensis, the records of the present study correspond to the first reports of parasites in the literature. This work provides also data on site of infection, parasite load, and development stages for the parasite species.
