Every 100 kcal of swordfish brings 13.6 g of protein. On that measure it ranks 87th of the 121 seafood in this database and 178th of all 796 foods on the site. Measured by weight instead, its 23.4 g per 100 g ranks 62nd in its group.
Protein accounts for roughly 54% of the calories in swordfish, 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, swordfish has 3 g of protein for each gram of fat (23.4 g against 7.93 g per 100 g).
Set against cod, another seafood entry in the database, a serving carries about 0.5 g more protein (cod has 19.4 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 40% of the 50 g FDA Daily Value for protein.
A high-mercury species that pregnant people are advised to avoid.

23.4 g. The 3 oz cooked serving used on this page weighs 85 g and so carries 19.9 g.
How much protein do you get per 100 calories of swordfish?
13.6 g. That figure divides its 23.4 g of protein per 100 g by its 172 kcal per 100 g, so it does not depend on serving size.
Is the protein in swordfish complete?
Yes. The protein in swordfish 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 swordfish?
About 40%. One 3 oz cooked serving has 19.9 g, and the FDA Daily Value for protein is 50 g.
