In this study we report the presence of paralarvae and juveniles oflllex argentinus in the waters of Nuevo Gulf (42°45'S-64°45'W, Argentina) during three consecutive years (2004-2007). Paralarvae were caught using a Hensen net of 295 µm mesh size. Juveniles were found stranded on the coast in September 2007. These findings show that the species uses near-shore waters for breeding.
