Bottom line
Per 100 g, Cod (Atlantic, Raw) provides 66 kcal, 16.1 g protein, 0 g carbohydrate and 0.7 g fat; Haddock provides 74 kcal, 16.3 g protein, 0 g carbohydrate and 0.5 g fat.

Two white fish from the same family and close enough in the pan that most recipes accept either. Cod comes in thicker flakes and holds together better in a bake; haddock is finer and slightly sweeter, which is why it dominates in smoked form. Cook either to 145°F.
In short: for protein per calorie, cod. If that is not the deciding factor, pick by the dish, the price and how you plan to cook it.
