Protein accounts for roughly 34% of the calories in pacific herring, making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, pacific herring has 1.2 g of protein for each gram of fat (21 g against 17.8 g per 100 g).
Set against scallops, another seafood entry in the database, a serving carries about 0.5 g more protein (scallops has 17.4 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 36% of the 50 g FDA Daily Value for protein.
