He also says "tuna fish" sandwich and I've always wondered why. He doesn't say "salmon fish" sandwich or ahi tuna fish sashimi... I know lots of people do say tuna fish - it is just a curiosity to me.
I grew up on tuna fish salad sandwiches. Prickly pear fruits are called tuna but I doubt my family was wanting to make that particular distinction. I also learned cod fish at home, depending on the dish so codfish cakes, creamed codfish (both made with salted cod) but probably cod filet without the fish part.
Edited to add that I did wonder if tuna fish was a regional usage. I grew up in northern NY state and this usage seems less common here in SoCal.
