Every 100 kcal of caviar brings 9.3 g of protein. On that measure it ranks 106th of the 121 seafood in this database and 267th of all 796 foods on the site. Measured by weight instead, its 24.6 g per 100 g ranks 36th in its group.
Protein accounts for roughly 37% of the calories in caviar, 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, caviar has 1.4 g of protein for each gram of fat (24.6 g against 17.9 g per 100 g).
Set against imitation crab (surimi), another seafood entry in the database, a serving carries about 2.6 g less protein (imitation crab (surimi) has 6.5 g per 3 oz).
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 volume at 16 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
Protein-dense by weight, but a normal serving is only a spoonful.

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.
24.6 g. The 1 tbsp serving used on this page weighs 16 g and so carries 3.9 g.
How much protein do you get per 100 calories of caviar?
9.3 g. That figure divides its 24.6 g of protein per 100 g by its 264 kcal per 100 g, so it does not depend on serving size.
Is the protein in caviar complete?
Yes. The protein in caviar 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 caviar?
About 8%. One 1 tbsp serving has 3.9 g, and the FDA Daily Value for protein is 50 g.
