Fishes were collected from Nuevo and San Jose´ gulfs, Argentinean Sea, from April 2003 to February 2005. The following parasites were found: Microsporidia (xenomas); Cestoda: Tetraphyllidea plerocercoid larvae; Digenea: Prosorhynchoides sp. metacercariae (Bucephalidae), Aponurus laguncula, Lecithaster sp. (Lecithasteridae), Proctotrema sp. (Monorchiidae), Diphterostomum sp. (Zoogonidae); Nematoda: Cucullanus marplatensis (Cucullanidae), Huffmanela moraveci (Trichosomoididae), Cosmocephalus obvelatus L3 (Acuariidae), Anisakis sp. L3, Pseudoterranova sp. L3, Contracaecum sp. L3 (Anisakidae); Acanthocephala: Corynosoma sp. cystacanth larvae (Polymorphidae), Hypoechinorhynchussp. (Arhythmacanthidae); Crustacea: Bomolochus globiceps (Bomolochidae) and Peniculus sp. (Penelidae). Odontesthes smitti and O. nigricans are new host records for most these parasites.
