A typical 3 oz cooked serving of catfish contains 15.6 grams of protein (18.4 g per 100 g), which makes it a very good source of protein. That covers roughly 31% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 51% of the calories in catfish, 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, catfish ranks 94th by protein per serving, and 234th out of all 796 foods on the site. Set against oysters, another seafood entry in the database, a serving carries about 0.5 g less protein (oysters has 16.1 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.
