Odontesthes bonariensis is a freshwater teleost fish from the Pampean inland waters, with an important economic potencial. The conditions of its intensive culture systems favour the proliferation of pathogen agents. This work describes the ocurrence of Achlya racemosa Hildebrand on eggs, and of Saprolegnia ferax (Gruith.) Thuret on a juvenile of Argentinian silverside (Odonthestes bonariensis). These represent new records for Argentina and are reported for the first time as agents of saprolegniosis for this native freshwater fish.is a freshwater teleost fish from the Pampean inland waters, with an important economic potencial.
