In Danish waters are the fish type whitefish. The term covers species such as turbot, cod and pike which I often see in the window of a fishmonger. White fish is a fish that swims slowly therefore the meat is white.
The tuna as also known as one of the ocean’s fastest swimmers that is way meat is red.
