Every 100 kcal of eel brings 10 g of protein. On that measure it ranks 105th of the 121 seafood in this database and 253rd of all 796 foods on the site. Measured by weight instead, its 23.6 g per 100 g ranks 56th in its group.
Protein accounts for roughly 40% of the calories in eel, 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, eel has 1.6 g of protein for each gram of fat (23.6 g against 15 g per 100 g).
Set against canned clams, another seafood entry in the database, a serving carries about 0.5 g less protein (canned clams has 20.6 g per 3 oz drained).
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.

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.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
23.6 g. The 3 oz cooked serving used on this page weighs 85 g and so carries 20.1 g.
How much protein do you get per 100 calories of eel?
10 g. That figure divides its 23.6 g of protein per 100 g by its 236 kcal per 100 g, so it does not depend on serving size.
Is the protein in eel complete?
Yes. The protein in eel 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 eel?
About 40%. One 3 oz cooked serving has 20.1 g, and the FDA Daily Value for protein is 50 g.
