Mahi mahi a hawaiian dish was once called what?

Mahi mahi is not a Hawaiian dish, it is a type of fish. It is a Hawaiian name, though.

While it is commonly called mahi mahi, it was once called "dolphin" in English. This can cause confusion as it refers to the fish and not the marine mammal.

Today, the term "dolphin" is rarely used for the fish to avoid this confusion.
