A typical 3 oz cooked serving of yellow perch contains 21.2 grams of protein (24.9 g per 100 g), which makes it a very good source of protein. That covers roughly 42% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
About 85% of the calories in yellow perch 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, yellow perch ranks 30th by protein per serving, and 122nd out of all 796 foods on the site. Set against ahi tuna (raw), another seafood entry in the database, a serving carries about 0.5 g more protein (ahi tuna (raw) has 20.7 g per 3 oz raw).
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.
