A 3.5-ounce (100-gram) serving of cooked salmon contains 22 to 25 grams of protein, depending on the species and whether it’s wild or farmed. That single serving covers roughly 40 to 50 percent of the daily protein needs for an average adult. Few foods pack this much protein into such a small portion while also delivering omega-3 fatty acids and other nutrients.
Protein by Salmon Species
Not all salmon is created equal when it comes to protein. Wild salmon consistently delivers more protein per serving than farmed salmon. A 3.5-ounce cooked serving of wild Atlantic salmon provides about 25.4 grams of protein, while the same amount of farmed Atlantic salmon comes in at 22.1 grams. The difference comes down to diet and activity level: wild fish swim harder and eat a more varied diet, which produces leaner, more protein-dense flesh.
Among wild species, the numbers look like this for a standard 3-ounce (85-gram) cooked serving:
- Sockeye: 23 grams
- King (Chinook): 22 grams
- Pink: 21 grams
- Chum: 22 grams
Sockeye edges out the others slightly, making it the most protein-dense species per ounce. Pink salmon, the most affordable variety and the kind most commonly found in cans, still delivers a solid 21 grams per serving.
How Salmon Compares to Chicken and Other Proteins
Chicken breast is often considered the gold standard for lean protein, and it does contain more protein per gram: about 31 grams per 100-gram cooked serving compared to salmon’s 25. But that 6-gram gap doesn’t tell the full story. Salmon brings omega-3 fats, vitamin D, and selenium that chicken breast simply doesn’t provide in meaningful amounts. If your goal is to maximize protein per bite and nothing else, chicken wins. If you’re looking at overall nutritional value per serving, salmon is hard to beat.
A typical salmon fillet at a restaurant or grocery store weighs between 5 and 7 ounces cooked. That means a single fillet can deliver 35 to 45 grams of protein in one meal.
Salmon Is a Complete Protein
Salmon contains all nine essential amino acids your body can’t make on its own. It’s particularly rich in leucine, lysine, and isoleucine, which play key roles in muscle repair, immune function, and energy production. This makes it a complete protein source on par with eggs, dairy, and meat. You don’t need to pair it with other foods to get the full amino acid profile your body needs.
Wild vs. Farmed: The Protein Tradeoff
Farmed salmon has about 3 grams less protein per 100-gram serving than wild salmon. It also tends to be higher in fat, including more saturated fat, because farmed fish get less exercise and eat a controlled diet. That extra fat dilutes the protein concentration by weight. So if you weigh out identical portions, the wild fillet gives you more protein and fewer calories.
That said, farmed salmon is still a high-protein food by any standard. At 22 grams per 3.5-ounce serving, it outperforms most cuts of pork, many beef cuts, and nearly all plant-based protein sources. If farmed salmon fits your budget better, you’re still getting a very protein-rich meal.
How Cooking Affects the Numbers
Cooking concentrates salmon’s protein. Raw salmon contains less protein per 100 grams than cooked salmon because heat drives out moisture, reducing the weight of the fillet while leaving the protein intact. A raw fillet that weighs 6 ounces might shrink to about 4.5 to 5 ounces after baking or grilling, but the total grams of protein stay nearly the same. This means the cooked portion is more protein-dense by weight.
The cooking method itself doesn’t significantly change the protein content. Baking, grilling, poaching, and pan-searing all preserve the amino acids. What changes is the calorie count: pan-frying in oil or butter adds fat calories, while poaching or baking keeps the calorie count lower. If you’re tracking macros closely, weigh your salmon raw and use raw nutrition data, or weigh it cooked and use cooked values. Mixing the two will throw off your numbers.
Canned Salmon Protein Content
Canned salmon is one of the most affordable and convenient ways to hit your protein targets. Most canned varieties use pink or sockeye salmon, and a standard 3-ounce drained portion delivers 21 to 23 grams of protein. The canning process doesn’t destroy protein. It softens the bones, which you can eat for an extra boost of calcium, but the protein remains fully intact. For meal prep, salads, or quick lunches, canned salmon gives you nearly the same protein as a fresh fillet at a fraction of the cost.
