Every 100 kcal of haddock brings 22.2 g of protein. On that measure it ranks 5th of the 121 seafood in this database and 7th of all 796 foods on the site. Measured by weight instead, its 20 g per 100 g ranks 86th in its group.
About 89% of the calories in haddock come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Weight for weight, haddock has 36.4 g of protein for each gram of fat (20 g against 0.55 g per 100 g).
Set against calamari, another seafood entry in the database, a serving carries about 0.5 g more protein (calamari has 16.5 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 85 g, and it covers about 34% of the 50 g FDA Daily Value for protein.
