How much protein is in salmon?

Protein, plus something almost no other protein gives you

On the protein line alone, salmon looks a lot like chicken or tuna: a cooked 3 oz serving carries about 18.8 grams, and a full dinner-sized fillet far more. That’s a complete protein — all nine essential amino acids in the amounts your body can actually use — so as a muscle-building or satiety food it stands on its own.

But protein isn’t really why salmon is worth singling out. Plenty of foods hit 20-plus grams. What salmon does that almost none of those others can is deliver that protein alongside a serious dose of omega-3 fats (EPA and DHA) — the long-chain fats tied to heart and brain health that are genuinely hard to get from food. Chicken breast and white fish give you lean protein and little else; a tin of tuna gives you some omega-3; salmon gives you a meaningful amount in a single normal serving. You’re not choosing between “lean protein” and “healthy fats” — you get both in the same bite.

What the numbers actually describe (and where they shift)

The figures on this page come from the USDA’s reference for Atlantic salmon, farmed, cooked by dry heat — roughly 22 grams of protein per 100 grams, or about 19 grams in a 3 oz portion. Two things are worth knowing before you apply them.

First, portion size is where the real protein lives. Nobody eats 85 grams of salmon at dinner. A standard restaurant or home fillet is closer to 6 oz cooked (~170 g), which lands around 38 grams of protein — close to an entire day’s requirement for a smaller adult in one piece of fish. Scale to an 8 oz fillet and you clear 50 grams. When people underestimate how much protein they’re getting from salmon, it’s almost always because they’re picturing a 3 oz card and eating a fillet twice that size.

Second, farmed versus wild barely moves the protein, but it does move the fat. Farmed Atlantic (the reference here) runs fattier, which means more omega-3 per serving and slightly more calories. Wild species — sockeye, coho, pink — are leaner: a touch less fat, a touch less omega-3, marginally fewer calories, with protein sitting in the same low-20s-per-100g band. Neither is “more protein” in any way you’d notice on a plate. If you’re optimizing for omega-3 per dollar, farmed is often the quiet winner; if you want the leanest version, reach for wild sockeye.

The cheap, shelf-stable way to get it

You don’t need a fresh fillet to get salmon’s protein-and-omega-3 combination. Canned salmon is the pantry version — far cheaper, shelf-stable, and nutritionally close to a cooked fillet ounce for ounce once drained. Canning doesn’t hurt the protein, and it adds two things a fillet doesn’t: the soft, fully edible bones, which are a real source of calcium most people throw away, and a built-in convenience that makes salmon a weeknight protein instead of a project. Because salmon sits low on the food chain, it also carries far less mercury than large predators like swordfish or albacore tuna, so it’s a fish you can eat often without watching accumulation. The graded canned options below are where to start.

Fitting it into a daily target

If you’re tracking protein, salmon is one of the easiest foods to build a meal around: one 6 oz fillet covers roughly a third of a 120-gram daily goal, and it brings fats most other proteins make you source separately. The trick is knowing your number first — our guide on how much protein per day walks through how to set it based on your weight and goals, and from there a fillet or a tin of salmon slots in without much math.
