I understand why add the word fish to make compound words for types of fish that would wouldn’t realize were fish without it, such as swordfish, catfish, sunfish whereas we don’t need to add fish to salmon, mackerel, trout, bass. So why do we add fish to tuna? Is there some other type of tuna than tuna fish?
