How the Type of Salmon Affects Calorie Count
The number of calories in 10 oz of raw salmon varies primarily based on whether the fish is wild-caught or farm-raised. This difference is a direct result of their environment, diet, and lifestyle, which impacts their overall fat content. Wild-caught salmon is leaner and more muscular from swimming in its natural ocean habitat, whereas farmed salmon is fed a controlled, higher-fat diet to promote rapid growth.
For a 10-ounce portion, the caloric differences are notable:
- Wild-Caught Salmon: A 10-ounce portion of wild Atlantic salmon contains roughly 403 calories. A similar serving of wild Coho salmon has about 414 calories, while wild Pink salmon is leaner, at around 360 calories for the same weight.
- Farmed Salmon: In contrast, 10 ounces of raw, farm-raised Atlantic salmon can be higher in calories, often exceeding 500, due to its increased fat content. The average farmed salmon contains about 206 calories per 100 grams (3.5 ounces), which extrapolates to approximately 588 calories per 10 ounces.
A Comparison of Wild-Caught vs. Farmed Salmon (10 oz Raw)
| Nutritional Aspect | Wild-Caught Raw Salmon | Farmed Raw Salmon |
|---|---|---|
| Estimated Calories | 360–415 kcal | 500–600+ kcal (dependent on fat) |
| Total Fat | Generally lower | Generally higher (up to 44g+) |
| Protein | Higher concentration | Similar, but often less concentrated |
| Omega-3s | Higher, healthier omega-3 to omega-6 ratio | Higher omega-6 fatty acids due to feed |
| Taste | Richer, more complex flavor; firmer texture | Milder, fattier, buttery flavor; softer texture |
| Contaminants | Less exposure to industrial pollutants | Potential for higher levels of PCBs and pollutants |
| Environmental Impact | Sustainable, contributes to natural ecosystems | Concerns about pollution and impact on local waters |
The Complete Nutritional Profile of Raw Salmon
Beyond just the calories, raw salmon is a nutritional powerhouse. A 10-ounce serving delivers a substantial amount of high-quality protein and essential nutrients that are vital for overall health. The protein helps build and repair tissue, while the fats are heart-healthy omega-3s.
Here is a list of some key nutrients found in a typical 10 oz serving of wild raw salmon:
- Omega-3 Fatty Acids (EPA and DHA): Raw salmon is one of the best sources of these crucial fatty acids, which support heart health, reduce inflammation, and enhance brain function.
- B Vitamins: Raw salmon is rich in a spectrum of B vitamins, including B12, B6, and B3 (niacin), which are essential for energy production, nerve function, and red blood cell formation.
- Vitamin D: Salmon is one of the few natural dietary sources of Vitamin D, which is critical for bone health, immune function, and regulating mood.
- Minerals: Important minerals found in salmon include potassium, selenium, and phosphorus. Selenium acts as a powerful antioxidant, protecting cells from damage.
- Antioxidants: The pinkish-orange color of salmon comes from astaxanthin, a carotenoid antioxidant that has been linked to numerous health benefits, including reduced risk of certain cancers.

Understanding the Risks of Consuming Raw Salmon
While eating raw salmon can offer maximum nutritional benefits, it comes with potential risks, primarily related to parasites and bacteria. These can cause foodborne illnesses, particularly in vulnerable populations such as pregnant women, young children, and those with compromised immune systems. To minimize these risks, it is essential to source raw salmon from a reputable provider and ensure it has been properly flash-frozen to kill parasites.
Conclusion: Making an Informed Choice
In summary, 10 ounces of raw salmon is a nutrient-dense food, providing high-quality protein, omega-3 fatty acids, and a wealth of vitamins and minerals. The calorie count can range from approximately 360 to over 500 kcal, depending heavily on whether the salmon is wild-caught or farm-raised. Wild salmon is generally leaner and lower in calories, while farmed salmon is fattier. When consuming raw salmon, always prioritize safety by sourcing high-quality, sushi-grade fish that has been handled and frozen correctly. By understanding these key distinctions, you can make a choice that best fits your dietary goals and preferences.
