A typical 1 oz dried serving of salt cod contains 17.6 grams of protein (62.8 g per 100 g), which makes it a very good source of protein. That covers roughly 35% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
About 87% of the calories in salt cod come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Among the 121 seafood in the database, salt cod ranks 77th by protein per serving, and 196th out of all 796 foods on the site. Set against breaded fried shrimp, another seafood entry in the database, a serving carries about 0.6 g less protein (breaded fried shrimp has 18.2 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 weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Salt-cured and dried, so protein is very concentrated by weight; it is soaked before cooking.
