Every 100 kcal of catfish brings 12.8 g of protein. On that measure it ranks 90th of the 121 seafood in this database and 194th of all 796 foods on the site. Measured by weight instead, its 18.4 g per 100 g ranks 97th in its group.
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.
Weight for weight, catfish has 2.6 g of protein for each gram of fat (18.4 g against 7.19 g per 100 g).
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 quoted here is measured by weight at 85 g, and it covers about 31% of the 50 g FDA Daily Value for protein.

Per-100 g values are the amino acid analysis on the USDA record. The serving and per-gram-of-protein columns are arithmetic on those values; they are not a protein quality score.

18.4 g. The 3 oz cooked serving used on this page weighs 85 g and so carries 15.6 g.
How much protein do you get per 100 calories of catfish?
12.8 g. That figure divides its 18.4 g of protein per 100 g by its 144 kcal per 100 g, so it does not depend on serving size.
Is the protein in catfish complete?
Yes. The protein in catfish supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of catfish?
About 31%. One 3 oz cooked serving has 15.6 g, and the FDA Daily Value for protein is 50 g.
