haddock

Haddock is primarily used in culinary and commercial contexts to describe a specific type of white fish. While it is closely related to cod, it is distinguished by a slightly sweeter flavor and a finer flake, making it a staple in British and North Atlantic cuisines, particularly in dishes like fish and chips.

In a biological or commercial sense, the word is often treated as an uncountable mass noun when referring to the fish as a food source or a commodity (e.g., "fresh haddock"). However, it remains countable when referring to individual fish in a biological or fishing context.
