Chebez & Athor (2009), Cousseau & Rosso (2019), Mabragaña & Cousseau (2021), referring to the book of Gon & Heemstra, but actually meaning the chapter written by Nakamura, considered the Southern Bluefin Tuna to be part of the Argentinean marine ichthyofauna. As a matter of fact Nakamura (1990) indicated this species to be “distributed throughout temperate and cold seas of the Southern Hemisphere, mainly between 30° and 50°S ”, a very general statement with no references to Argentina or even the Southwestern Atlantic Ocean. Galván et al. (2021) even mentioned an “anecdotic occurrence” for the records from Argentina.
