A typical 3 oz cooked serving of bluefish contains 21.8 grams of protein (25.7 g per 100 g), which makes it a very good source of protein. That covers roughly 44% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
About 65% of the calories in bluefish 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.
Among the 121 seafood in the database, bluefish ranks 24th by protein per serving, and 111th out of all 796 foods on the site. Set against tilapia, another seafood entry in the database, a serving carries about 0.5 g less protein (tilapia has 22.3 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 measured by weight at 85 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
