The Real Name and Origin of Chilean Sea Bass

The fish commonly known as Chilean sea bass is not originally from Chile, despite its name. Its real name is Patagonian toothfish (Dissostichus eleginoides), a species native to the cold waters of the Southern Hemisphere. The name "Chilean sea bass" was coined by a fish wholesaler in the 1970s to make the fish more marketable to American consumers.

How Did It Get Its Name?

The renaming of Patagonian toothfish to Chilean sea bass was a marketing strategy that transformed the perception of this fish.
