You're standing at the seafood counter, or maybe you're staring at a vacuum-sealed pack of frozen fillets, wondering if that slab of pink fish is actually as healthy as everyone says. Most people just want a straight answer. They want to know the calories in 6 oz of salmon so they can log it into an app and move on with their day. But here's the thing: salmon isn't just "salmon."
Asking for the calorie count of a piece of fish is a bit like asking how much a bag of groceries weighs without knowing if the bag is full of feathers or lead. A 6 oz piece of wild-caught Sockeye is a completely different beast than a 6 oz portion of Atlantic farmed salmon. One is lean and muscular; the other is basically the ribeye of the sea.
The Basic Math: Breaking Down the Numbers
Let's get the raw data out of the way first because that’s why you’re here. If you grab a standard raw, wild Atlantic salmon fillet, you’re looking at roughly 240 to 260 calories for a 6 oz serving.
That’s a solid, protein-dense meal. However, if that salmon is farmed—which accounts for about 75% of the salmon consumed globally—those numbers jump. Farmed salmon is fattier. It lives a more sedentary life and eats a controlled, high-fat diet. A 6 oz portion of farmed Atlantic salmon can easily hit 350 to 380 calories. That is a massive difference of over 100 calories just based on how the fish was raised.
It gets even more granular when you look at species.
King Salmon (Chinook) is the heavyweight champion of fat content. It's buttery. It's delicious. It’s also about 390 calories per 6 oz. On the flip side, Pink salmon or Chum salmon are much leaner, often hovering around 210 to 220 calories for that same 6 oz weight.
Weight matters too, obviously.
We’re talking about 6 oz raw weight here. Most people don’t realize that fish loses about 25% of its weight during cooking because of water loss. If you weigh your salmon after it comes off the grill and it hits 6 oz on the scale, you actually started with about 8 oz of raw fish. In that case, you’re looking at closer to 450-500 calories for farmed varieties.
Why the Fat Content Changes Everything
Salmon is famous for its fats. Specifically, those Omega-3 fatty acids that doctors and biohackers won't stop talking about. According to the USDA FoodData Central, the lipid profile of salmon varies more than almost any other common protein.

Wild salmon spend their lives swimming thousands of miles. They are athletes. Their flesh is packed with protein and a specific type of fat called phospholipids. Farmed salmon, however, have higher levels of triglycerides. This doesn't mean farmed salmon is "bad"—it still has those essential Omega-3s—but it does mean the calorie density is much higher.
Honestly, if you're tracking macros, you have to account for this. A 6 oz wild Coho fillet might have 9 or 10 grams of fat. A 6 oz farmed fillet can have 20 to 25 grams of fat. That’s more fat than a large order of fast-food fries.
The Cooking Method: The "Hidden" Calories
You can take a perfectly healthy 250-calorie piece of wild salmon and turn it into a 600-calorie salt bomb real quick.
Most people don't just steam their fish in plain water. We use olive oil. We use butter. We use honey-mustard glazes or maple syrup reductions. One tablespoon of olive oil adds 120 calories. One tablespoon of butter adds about 100. If you’re pan-searing that 6 oz fillet in a pool of fat, you’ve effectively doubled the energy density of the meal before you even put it on the plate.
Then there's the skin.
Keep it on. Seriously.
The skin is where a huge concentration of the nutrients live, but it’s also where the fat is stored. If you eat a 6 oz fillet with the skin crisped up, you’re adding roughly 30 to 50 calories compared to a skinless portion. It's worth it for the flavor, but it’s a factor.
How Salmon Compares to Other Proteins
Is 6 oz of salmon "a lot" of calories?

Compare it to 6 oz of chicken breast. Chicken is incredibly lean, coming in at about 280 calories for 6 oz (cooked). Salmon is often higher in calories than chicken, but lower than a 6 oz ribeye steak, which can easily soar past 450 calories.
The difference is the type of calorie. Salmon provides Vitamin D, B12, and Selenium. More importantly, it provides EPA and DHA. Research from the Harvard T.H. Chan School of Public Health suggests that eating oily fish like salmon twice a week can reduce the risk of heart disease by 36%. You aren't just eating calories; you're eating preventative medicine.
Common Myths About Salmon Calories
One thing people get wrong all the time is the "color" myth. They think the deeper the red, the higher the calories. Not true.
Sockeye salmon is famously deep red because of its diet of krill and plankton, which are rich in a pigment called astaxanthin. Sockeye is actually quite lean compared to the lighter-pink farmed Atlantic salmon. Color is an indicator of diet and species, not necessarily fat or calorie load.
Another misconception is that frozen salmon has fewer calories or less nutrition. Nope.
Flash-freezing happens almost immediately after the catch. The calorie count in 6 oz of salmon remains identical whether it was frozen six months ago or caught yesterday. The only thing that changes is the texture if you defrost it poorly.
Practical Ways to Track This Accurately
If you’re serious about your intake, stop guessing. Use a kitchen scale.

- Weigh it raw if you can. This is the gold standard for accuracy.
- If you're at a restaurant, a 6 oz portion is roughly the size of two decks of playing cards.
- Assume any restaurant salmon is farmed (and thus higher calorie) unless they specifically brag about it being "Wild Alaskan" on the menu.
- Be wary of "Glazed" or "Crusted" descriptions. A pecan-crusted salmon can add 200 calories in nuts and binders alone.
Summary of the Numbers
For a quick reference on calories in 6 oz of salmon, keep these rough estimates in your head:
- Wild Sockeye/Coho: 230–260 calories.
- Farmed Atlantic: 340–380 calories.
- King (Chinook): 370–400 calories.
- Canned Salmon (Drained): 240 calories.
Actionable Steps for Your Next Meal
If you want the benefits of salmon without the calorie creep, start by changing your prep. Instead of pan-frying in oil, try poaching the fish in a flavorful liquid like lemon water, white wine, or a light dashi broth. This keeps the fish incredibly moist without adding a single gram of extra fat.
If you prefer a sear, use a high-quality non-stick pan or a cast-iron skillet and just a tiny spritz of avocado oil. Avocado oil has a high smoke point, so you get that crispy exterior without needing to deep-fry the fillet.
For those trying to gain muscle or healthy weight, lean into the farmed Atlantic varieties or the King salmon. The extra fat calories are an easy way to bump up your daily intake while getting those anti-inflammatory benefits.
Final tip: check the label for "Added Salt" or "Brine." Some cheaper salmon brands inject the fish with a saline solution to increase weight. It doesn't add calories, but it will make you bloat like crazy from the sodium. Stick to single-ingredient fish whenever possible.
