8 oz Salmon Protein & Nutrition

By: Jeremy Fox, CNC, CPTPublished: December 12, 2022

Salmon is packed with flavor, omega-3s, and protein. So it should be at the top of your seafood shopping list!

Now you might wonder what kind of salmon has the most protein and best nutritional value. The answer to that can vary depending on several factors, including the type of salmon you purchase.

So this article is your guide to choosing the most nutritious salmon, including a comparison of the protein, fat, and calorie content of various types of salmon.

8 oz Salmon Nutrition

A typical 8 oz salmon filet contains around 48 grams of protein, 16 grams of fat, 0 carbs, and 346 calories. However, you also need to know that 8 ounces of salmon can have different nutritional values depending on several factors.

First, protein can differ between salmon species due to meat and oil content variations. In addition, wild-caught vs farm-raised salmon have different amounts of fat and calories.

Finally, the exact nutrition amounts in salmon depend on whether you weigh it raw or cooked.

Factors That Affect Salmon Nutrition:

  • Type/Species
  • Wild-caught vs. Farm-raised
  • Raw vs. Cooked

Now let’s look at different types of salmon to see how much protein is in an 8 oz portion.

Protein In 8 oz Salmon By Variety

In the United States, there are generally six types of salmon available at the grocery store; Atlantic, King/Chinook, Sockeye/Red, Coho/Silver, Pink/Humpback, and Chum/Keta/Dog. You’ll notice most species go by two or more names.

Nearly all Atlantic salmon available in the grocery store is farm raised. While the other five types come from the Pacific Ocean and could be either wild-caught or farm-raised.

Each species of salmon grows to different sizes and body compositions based on its habitat and diet. So the salmon nutrition values also differ between types.

Here is a table showing the nutrient profile for the six varieties of salmon.

Table 1. Protein In 8 oz Salmon by Type

Type Protein Fat Calories
Atlantic Salmon 46 g 30 g 472
King/Chinook Salmon 46 g 26 g 424
Coho/Silver Salmon 50 g 14 g 372
Sockeye/Red Salmon 50 g 10 g 298
Pink/Humpback Salmon 46 g 10  g 288
Chum/Keta/Dog Salmon 46 g 8 g 272
Average 48 g 16 g 346

As shown in the table above, the protein in 8 oz of salmon is fairly consistent, ranging from 46 to 50 grams. However, you should go for Coho/Silver or Sockeye/Red salmon to get the most protein.

In addition, the fat content can range from as low as 4 grams to as high as 15 grams per 4 oz. To reap the benefits of Omega-3 fish oils, you may want to select Atlantic or King/Chinook salmon.

Moreover, the variation in fat results in significantly different calories between the salmon types. So if you’re looking for a low-calorie option, you might opt for Pink or Chum salmon.

Protein In Atlantic Salmon

A typical 8 oz Atlantic salmon fillet contains 46g of protein. In addition, an 8 oz portion comes in at a whopping 30g of fat, which adds up to about 472 calories.

Again, this is the only species of salmon originating from the Atlantic Ocean. And most of it comes from fish farms.

However, that doesn’t necessarily mean it’s worse for you than wild salmon. And there are trade-offs to consider with every type of fish.

Protein In King/Chinook Salmon

King/Chinook salmon fillets contain 46g of protein per 8 ounces. And it has about 26g of fat, for a total of 424 calories.

One interesting fact is that the king salmon gets its name for being the largest salmon in the Pacific, growing as large as 50 lbs. In addition, they have the highest fat content among wild-caught salmon, which adds flavor.

Moreover, king/chinook salmon is some of the most expensive on the market, making it a meal fit for a king.

Protein In Coho/Silver Salmon

Next on the list is Coho/silver salmon, coming in at 50g of protein per 8 ounces. With 14g of fat, it only contains 332 calories.

Coho salmon are also called silver salmon due to their striking silver sides during their ocean phase of life. And they are a popular choice for cooking thanks to a balance of flavor, quality, and cost.

Protein In Sockeye/Red Salmon

The sockeye or red salmon is another high-protein option with 50g per 8 oz serving. And it has just 10g of fat, making it a lean 298-calorie meal.

Sockeyes are often called red salmon because of the crimson coloration male fish take on during spawning. Like a defined muscle, sockeye salmon fillets have a dense, firm texture that lends itself well to sushi or grilling.

Protein In Pink/Humpback Salmon

Pink salmon is among the leanest varieties, with 10g of fat and 46g of protein per 8 ounces. As a result, it has only 288 calories per serving.

Male pink salmon develop a distinctive hump on their backs during spawning migration, which is why they are sometimes called humpback salmon.

From a cooking standpoint, the lack of fish oil makes it dry out easily. So it’s not typically one of the most sought-after salmon fillets, although it is often sold in canned form.

Protein In Chum/Keta/Dog Salmon

Chum salmon has the lowest fat content among all salmon types, with only 8g per 8 ounces. And with 46g of protein, it has just 272 calories.

This salmon species gets its name because it was historically used as feed (chum) for dog sled teams. However, chum salmon can be enjoyed by people as well. And it is best prepared by slow cooking methods like smoking.

Wild-Caught vs Farm-Raised Salmon Nutrition

The biggest difference between wild-caught and farm-raised salmon is what they eat. And this, in turn, affects the nutritional profile and potential contaminants in the fish we consume.

In their natural habitat, salmon feed on shrimp and krill as they migrate from the ocean and swim up coastal streams. However, they also consume pollutants dumped in the water by humans, which seep into their meat.

On the other hand, farm-raised salmon are fed pellets made from ground-up fish, chicken, and grains. Like people eating fast food, this calorie-dense diet increases the salmon’s body fat and makes them larger. But it takes away from their natural flavor and color.

In terms of protein content, there’s not much difference between wild and farmed salmon. The main nutritional difference is that farmed salmon generally has a higher fat and calorie content. 

Other factors affecting your salmon choice include environmental concerns, contaminants, and omega-3 fatty acid content. So look for a source of salmon that strikes the right balance for you.

Wild Caught vs Farm Raised Salmon Protein

Raw vs Cooked Salmon Nutrition

Another factor that affects the protein in 8 oz of salmon is whether you weigh it before or after cooking. The reason is that a salmon fillet loses about 25% of its weight during cooking (i.e., raw salmon weight x 0.75 = cooked salmon weight)

So if you start with 8 oz of salmon, it only weighs about 6 oz after cooking. And that 6 oz piece of cooked salmon would still have the original 48g of protein since the weight lost is from water evaporation, not meat degradation.

Furthermore, you can divide by 0.75 to find the protein in cooked salmon. For example, an 8 oz piece of cooked salmon would have 48g ÷ 0.75 = 64g of protein.

Knowing the protein content of cooked salmon is beneficial when you meal prep large quantities of fish to divide up later. But remember that the protein amount can vary depending on the cooking method, temperature, and duration.

How To Measure 8 oz Salmon

Of course, most salmon fillets don’t weigh precisely 8 oz. So how do you measure a serving of salmon? I have a few different ways to do it – with or without a scale.

With No Scale

First, you could try to buy packages of salmon in 8 oz increments, such as 8, 16, 24, etc. However, most of the time, salmon is sold by the pound. And since there is 16 oz in a pound,  look for packages weighing 0.50, 1.00, 1.50 lbs, and so on.

Next, cook all the salmon and divide it into equal portions. For example, if you bought 2.00 lbs (24 oz) of salmon, you would divide it into four equal portions after cooking (24 oz / 4 servings = 8 oz per serving).

Don’t worry about being perfect. Like if one portion is 7 oz and another is 9 oz, that’s okay! Because, over a few days, it all evens out.

As you can see, with some math, you never have to weigh anything!

With Scale

If math isn’t your thing, you can also measure salmon with a kitchen scale. And you can do this before or after cooking.

First, you can weigh 8 oz of uncooked salmon on your scale. Or you can weigh multiples of 8 oz to divide up after cooking (8, 16, 24, etc.)

You can also wait until after cooking to weigh the salmon. That way, you don’t have to mess with raw meat. Remember that salmon loses about 25% of its weight during cooking.

After cooking, you should weigh 10.67 oz portions to get the same protein content as 8 oz of raw salmon.

Salmon Compared to Other Protein Sources

While salmon is an excellent source of protein, certain types are also relatively high in fat and calories. So it may not be a perfect fit for your diet.

In addition, it might not be a good idea to eat salmon every day due to the risk of contamination. Plus, you would probably get sick of eating the same meal over and over!

The table below shows the protein, fat, and calories in other popular protein sources.

Table 2. Protein, Fat, & Calories In 8 oz of Salmon vs Other Meat

Protein Source Protein Fat Calories Protein:Calorie
Chicken Breast 52 g 3 g 240 0.22
Salmon 48 g 16 g 346 0.14
Pork Chop 47 g 21 g 378 0.13
Lean Ground Turkey 42 g 16 g 340 0.12
Sirloin Steak 46 g 24 g 420 0.11

I’ve sorted the table by the protein-to-calorie ratio, so you can see which food gives you the most protein per calorie. It turns out that salmon is the second-best low-calorie source of protein behind chicken breasts.
