While often celebrated for its healthy omega-3 fatty acids, not all salmon contains the same amount of fat. The fat content can vary significantly by species, diet, and whether the fish is wild-caught or farm-raised. For those seeking the leanest options, certain wild-caught Pacific species stand out.
The Leanest Salmon: Wild Pink and Chum
Wild pink and chum consistently rank among the lowest-fat salmon species. Their mild flavor and delicate texture result from their leaner profile.
Wild Pink Salmon
- Other names: Humpback salmon or "humpies".
- Fat content: As low as 0.8% wet weight, with an average around 4%.
- Flavor and texture: Light-colored, mild-tasting flesh with a very delicate texture.
- Availability: Most abundant, often canned, but also available fresh and frozen.
Wild Chum Salmon
- Other names: Keta or dog salmon.
- Fat content: Low average fat content, around 4%.
- Flavor and texture: Pale to medium-red flesh, mild flavor, firm texture with a large flake.
- Availability: Often used for roe or jerky, but also sold fresh.
Comparison of Salmon Fat Content
Fat content influences flavor and texture; higher-fat species like King salmon offer a rich taste, while leaner varieties are milder.
Comparison of Salmon Species by Fat Content and Characteristics
| Feature | Wild Pink Salmon | Wild Chum Salmon | Wild Sockeye Salmon | Wild King Salmon | Farmed Atlantic Salmon |
|---|---|---|---|---|---|
| Average Fat % (approx.) | 4% | 4% | 4.2% (wet weight) | >10.4% (wet weight) | ~11.6% (wet weight) |
| Omega-3s (mg/3oz cooked) | ~564mg | ~683mg | ~730mg | ~1,476mg | ~2,100mg |
| Flavor Profile | Mild, delicate | Mild, lean | Rich, bold, fishier | Very rich, buttery | Mild, buttery |
| Texture | Very tender | Firm, large flake | Firm, compact | Soft, flaky, melts easily | Softer, flaky |
| Typical Use | Canned, burgers | Smoking, jerky | Grilling, smoked, burgers | Grilling, high-end fillets | Versatile, fillets |
Wild Salmon vs. Farmed Salmon: The Fat Factor
Wild salmon is generally leaner than farmed salmon due to its active lifestyle. Farmed salmon's diet results in higher fat content.
- Higher fat: Farmed salmon often has more total fat. It can have higher omega-3s but sometimes with a less favorable omega-3 to omega-6 ratio than wild fish.
- Leaner profile: Wild-caught salmon is consistently leaner, with fewer calories per serving.
- Diet matters: The salmon's diet impacts its nutritional makeup.
The Best Way to Cook Lean Salmon
Lean salmon needs careful cooking to prevent drying. Gentle, moist heat methods are best.
- Poaching: Simmering in liquid keeps the fish moist and tender.
- Steaming: Cooks evenly without losing moisture.
- En Papillote: Baking in a sealed pouch steams the fish in its own juices.
- Pan-frying with care: Use a non-stick pan and minimal oil, cooking briefly.
Conclusion: Making the Right Choice
For those asking "what is the lowest fat salmon?", the answer is definitively wild pink and chum salmon. They are the leanest species, ideal for lower-fat diets. Fattier species like King or farmed Atlantic are suitable for a richer flavor profile and higher omega-3s. Proper cooking is key for lean salmon to retain its texture.

Cooking Recommendations for Lean Salmon
- Use a marinade: Marinades add moisture and flavor to lean salmon.
- Monitor cooking time: Cook lean salmon for a shorter time to avoid drying.
- Consider sauces: Light sauces can complement the mild flavor.
- Ideal for canning: Pink salmon is often used for canning.
