A typical 1 tbsp serving of caviar contains 3.9 grams of protein (24.6 g per 100 g), which makes it a moderate source of protein. That covers roughly 8% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
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.
Among the 121 seafood in the database, caviar ranks 120th by protein per serving, and 550th out of all 796 foods on the site. 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 above is measured by volume at 16 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Protein-dense by weight, but a normal serving is only a spoonful.
