trout, rainbow, farmed vs Salmon
Side-by-side nutrition comparison per serving. See which fits your goals better.
Trout and salmon are close relatives in the salmonid family, and their nutritional profiles reflect that kinship — with a few key differences. Trout delivers 19.9g protein at 141 calories per 100g with 6.18g fat. Salmon provides 20.4g protein at 208 calories with 13.4g fat. Trout is significantly leaner, carrying less than half of salmon's fat content.
The omega-3 content scales with fat: salmon's higher fat load means more EPA and DHA per serving. A 150g salmon fillet might deliver 3-4g of omega-3s, while the same portion of trout provides roughly 1.5-2g. Both are excellent sources, but salmon is the richer one. Trout compensates with fewer calories, making it better suited for calorie-conscious eaters who still want omega-3 benefits.
Flavor and availability often determine the practical choice. Rainbow trout has a milder, slightly nuttier taste than salmon and is less likely to be farmed in crowded ocean pens — most farmed trout is raised in freshwater raceways with better environmental practices. Price-wise, trout is typically 20-40 percent cheaper than salmon, making it the budget omega-3 option.
Pro tip
Whole trout is one of the easiest fish to cook at home. Stuff the cavity with lemon slices, fresh dill, and garlic, then roast at 200 degrees Celsius for 20 minutes. The bones make it easy to peel off perfectly cooked fillets, and a whole trout feeds two people for under ten dollars.
