One of the most popular species of salmon, the sockeye is found in the northern Pacific Ocean. Most of the sockeye salmon you find in stores comes from Alaska. The flesh of the fish is dark orange to deep red, with a firm texture and richer taste than other species.
A fillet of salmon weighing 1/2 lb. contains 332 calories. The American Cancer Society recommends controlling portion sizes for health and points out that 3 oz. is a normal portion for fish. A 3 oz.-serving of wild sockeye salmon has 124.5 calories and 6.33 g of fat.
Wild sockeye salmon is a rich protein source, with nearly 16 g of protein in each 3-oz. serving. Each portion also contains close to 35 g of sodium, 318.9 g of potassium and 6 mg of calcium. Canning salmon with the bones increases the calcium content to 188 mg per serving.
Omega-3 Fatty Acids
Wild sockeye salmon is high in a type of omega-3 fatty acid called DHA that is important to health. DHA helps protect against heart disease, lowers cholesterol levels and may help slow Alzheimer's, according to Colorado State University Extension. Sockeye salmon contains 1,046 mg of DHA per serving, more than twice the recommended daily intake.
