A typical 3 oz serving of fried catfish contains 15.4 grams of protein (18.1 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 32% of the calories in fried catfish, 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.
Among the 121 seafood in the database, fried catfish ranks 97th by protein per serving, and 240th out of all 796 foods on the site. Set against crayfish, another seafood entry in the database, a serving carries about 0.5 g more protein (crayfish has 14.9 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.
Breading and frying roughly double the calories of a plain catfish fillet.
