A typical 1 large fillet serving of kippered herring contains 16 grams of protein (24.6 g per 100 g), which makes it a very good source of protein. That covers roughly 32% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 45% of the calories in kippered herring, making it very 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.
Among the 121 seafood in the database, kippered herring ranks 89th by protein per serving, and 224th out of all 796 foods on the site. Set against calamari, another seafood entry in the database, a serving carries about 0.5 g less 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 above is counted by piece at 65 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
