“Tuna fish” is a phase used primarily for canned tuna, but not for the live fish or things like tuna steak. It’s because when canned tuna was created in the US in the early 1900’s people who were not right next to the sea (like the majority of the US) did not know what “tuna” was. Firstly, the word is a of Spanish origin and secondly, its a salt water only fish. So in order to sell this to middle America, which was where most of the consumers were at the time but was also made up of people who have never seen the ocean, they added the word “fish” to show like other tinned fish that was commonly purchased: codfish, bluefish, and whitefish, this is also a fish and that is what you can expect when you open this can.
