Around 18% of the calories in fried oysters come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 121 seafood in the database, fried oysters ranks 117th by protein per serving, and 370th out of all 796 foods on the site. Set against anchovies (canned), another seafood entry in the database, a serving carries about 0.6 g less protein (anchovies (canned) has 8.1 g per 1 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 weight at 85 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
