Steelhead vs. Salmon: What's the Difference?

Steelhead and salmon are often used interchangeably, and they look extremely similar. But they're not the same. In fact, these two types of fish have some distinct differences that most don’t know about. So we’re going to clear the muddied water and talk about steelhead vs salmon. We'll delve into the characteristics of each fish and explore the unique qualities that make the difference between steelhead and salmon.

What is the Difference Between Steelhead and Salmon?

Steelhead and salmon are both species of fish that are part of the trout and salmon family, but they have some key differences:

Habitat

Steelhead and salmon have similar habitats as they are both anadromous fish that migrate from freshwater to saltwater and back again to spawn. However, there are some differences in their preferred habitats according to each species’ migratory behavior:

• Steelhead are more tolerant of warmer water temperatures than some species of salmon, which allows them to inhabit rivers and streams that may not be suitable for other salmon species.
• Steelhead can also live in freshwater for longer periods of time than most salmon species, sometimes up to several years, while most salmon species typically only spend a few months in freshwater before migrating back to the ocean.
• Salmon generally have more specific requirements for spawning habitat than steelhead, as they require clean, cool water with gravel beds for egg incubation.
• Different species of salmon have different preferences for spawning habitats, with some preferring larger rivers and others preferring smaller streams.
• Steelhead and salmon both prefer cold, clear water with high oxygen content, but steelhead are generally more adaptable to different water conditions and can tolerate a wider range of salinity levels in their habitat.

Overall, while there are some differences in their preferred habitats, both steelhead and salmon are adapted to migrate between freshwater and saltwater environments for different stages of their life cycle.

Size

Steelhead and salmon differ in size, with steelhead generally being larger than most salmon species.

Steelhead can grow up to 45 inches in length and weigh up to 55 pounds, although the average size is typically around 8 to 11 pounds. In comparison, most salmon species range in size from 4 to 8 pounds, although some species can grow larger.

The size of steelhead and salmon can also depend on their age, habitat, and diet. Steelhead tend to spend more time in the ocean than salmon, allowing them to grow larger before returning to freshwater to spawn. Steelhead also have a more varied diet than salmon, which can include smaller fish, squid, and crustaceans, whereas salmon primarily feed on small fish, krill, and plankton. Overall, while both steelhead and salmon can vary in size depending on their species and other factors, steelhead are generally larger than salmon.

The color of salmon's flesh can range from pale pink to bright red-orange, depending on the species and diet. Wild salmon tend to have a darker, richer color than farmed salmon, which can be paler due to their diet.

The vibrant color of salmon's flesh is due to their diet, which is rich in carotenoids, pigments that are found in algae, krill, and other small organisms that salmon consume. These pigments are important for salmon's health and also contribute to the color of their flesh.

Overall, while steelhead and salmon have similar pinkish-orange flesh, the color can vary depending on several factors, including species, diet, and habitat.

Availability

Steelhead and salmon availability can vary depending on the species and the region, but there are some general differences in their availability.

Steelhead is generally available year-round, although peak season varies by region. For example, steelhead fishing is most popular in the Pacific Northwest from November to April, while in the Great Lakes region, steelhead can be caught from September to June.

Salmon, on the other hand, is typically only available during certain seasons, as the fish migrate to their spawning grounds during specific times of the year. The availability of salmon can also depend on the species and the region. For example, Chinook salmon, also known as king salmon, are typically available from May to October in the Pacific Northwest, while Atlantic salmon is typically available from June to September in the Northeast.

In addition, some salmon species are more commonly farmed than caught in the wild, which can affect their availability. Farmed salmon is generally available year-round, although there may be seasonal variations in availability.

Overall, while steelhead is generally available year-round, salmon availability can vary depending on the species and the region, with some species only available during certain seasons.

Nutrition

Steelhead and salmon are both nutritious fish that are rich in protein and omega-3 fatty acids, which are important for heart and brain health. However, the exact nutritional content can vary depending on the species, age, and other factors.

In general, salmon is slightly higher in fat than steelhead, which can affect its nutritional profile. For example, a 3-ounce serving of wild salmon contains around 121 calories, 17 grams of protein, and 5 grams of fat, including 1 gram of saturated fat. The same serving of farmed salmon contains around 177 calories, 19 grams of protein, and 10 grams of fat, including 2 grams of saturated fat.

In comparison, a 3-ounce serving of steelhead contains around 119 calories, 20 grams of protein, and 3 grams of fat, including 1 gram of saturated fat. Steelhead is also a good source of B vitamins, potassium, and selenium.

Both salmon and steelhead are good sources of omega-3 fatty acids, which have been shown to have a range of health benefits, including reducing inflammation, improving heart health, and supporting brain function.
