First Report Of The Hapuku Wreckfish Polyprion Oxygeneios (Polyprionidae) In Argentinian Waters

The hapuku wreckfish Polyprion oxygeneios is recorded for the first time in Argentinian waters. Four specimens were caught off Mar del Plata (38 degrees S, Argentina) in depths between 60 and 260 m during austral summer (three by sport fishers and one in a research cruise). Up to the present, this species was consistently misidentified with its congener, the common wreckfish P. americanus, off Argentina. These records represent a connection between previous records from Brazil and the more austral circumglobal distribution of the species.
