Are Steelhead and Salmon the Same Thing?
No, despite being frequently confused with one another, steelhead and salmon are not the same thing. Both steelhead and salmon are members of the salmonids family and live in saltwater, however they are not the same species. Steelheads are actually a type of rainbow trout, not salmon. In the next few sections, we’ll look at the characteristics of each fish species, as well as the key differences between the two.
What is Steelhead?
As I just shared, steelhead are a member of the salmonid family, but they are not a type of salmon. Rather, they are a type of trout. Actually, they are the same species as a rainbow trout, but just live slightly differently. Whereas rainbow trout remain in freshwater throughout their lives, steelhead live in the sea for part of their life, then move to freshwater rivers when they are ready to breed. Steelhead trout can be found across the globe, though they are native to the freshwater and oceans of North America.
If you’re looking for the steelhead trout vs steelhead salmon difference, you’re not really going to find it. These are both just different terms that can be used to refer to the same fish. Technically, steelhead trout is the most accurate because steelhead are a type of trout. However, many people call this type of fish steelhead salmon because they migrate to the ocean and have a similar appearance to salmon.
What is Salmon?
Salmon are native to the Pacific Northwest, though now groups of salmon can be found all over. Like steelhead, salmon are anadromous fish. This means that part of their lives is spent in freshwater, while other parts are spent in the saltwater ocean. Salmon are born in freshwater rivers. Then, they swim to the saltwater ocean, where they’ll mature. Once they are ready to spawn, they return to the freshwater river to deposit their eggs.
What is the Difference Between Salmon and Steelhead?
What is the difference between steelhead and salmon? Now that we have a brief overview of each of these species, let’s take a deeper look at the key steelhead vs salmon differences.
Taste and Texture
While the taste of steelhead and salmon aren’t drastically different, they do each have a unique flavor. Steelhead trout tend to have a milder taste that isn’t as ‘fishy’ as salmon. This is even more true if you purchase farm-raised, as opposed to wild, steelhead. Steelhead trout tends to taste a bit less sweet than salmon as well.
When cooked correctly, both fish are very tender and flaky. They can be used in a variety of recipes and tend to absorb the flavors you cook with, which keeps them from overpowering the meal.
There are some minor differences in the texture of salmon and steelhead, but they aren’t very noticeable. Steelhead can be a bit firmer than salmon, while salmon may be a bit flakier.
Steelhead trout and salmon have a similar appearance, which is another reason these two fish are often mistaken for one another. They both have a silver-to-chrome colored body, which is relatively bright and shiny. Additionally, the overall body shape of both types of fish is similar. They both resemble torpedoes.
However, there are a few features to look for that can help you distinguish steelhead trout from salmon. First, steelhead trout have pink or red stripes along their sides. These stripes are pretty faint and may not always be visible.
Another difference in the appearance of these two types of fish lies in the shape of their head. While a salmon’s head comes to more of a point at their mouth, a steelhead trout’s head is a bit rounder.
One more key difference between steelhead and salmon is the color of their mouth and gum. Steelhead trout will have white gums and a white interior mouth color. On the other hand, the Pacific salmon species will have black or very dark gums.
However, this method of distinguishing the two types of fish isn’t foolproof. If you’re looking at an Atlantic salmon species, it will also have white gums and a white mouth, like a steelhead. So, when distinguishing steelhead vs Atlantic salmon, looking at the mouth and gums won’t be very helpful.
Size and Weight
While each fish’s specific habitat can impact their overall size and weight, generally speaking, salmon will be larger than steelhead trout. The average length of a steelhead trout is between 20 and 25 inches, while most salmon species will be at least 25 to 30 inches long, with some being up to 40 inches.
Likewise, salmon also weigh more than steelhead trout. Most steelhead trout have a maximum body weight around 20 pounds. Some species of salmon, including Atlantic salmon and Pacific king salmon, often weigh between 40 and 60 pounds, with some weighing considerably more.
Spawning is also different between salmon and steelhead. Salmon tend to spawn between September and December, while steelhead spawn between January and April.
After spawning, salmon will die (with the exception of a few Atlantic salmon). During the spawning process, a salmon’s body releases corticosteroids. These steroid hormones cause their bodies to deteriorate quickly, causing the fish to die. Some may die almost instantly, while others could continue to live for a few weeks.
For the most part, steelhead trout do not die after spawning. They are able to return to the saltwater ocean after spawning is complete, and will often return back to the freshwater again in the years that follow to spawn multiple times.
When you’re comparing different types of fish, it is also important to look at mercury levels. While all fish will have some mercury, some species absorb more than others. Limiting your intake of mercury is important, but especially so if you are pregnant or nursing.
Neither salmon nor steelhead trout contain very high levels of mercury. However, salmon contains a lower amount and is included on the FDA’s best fish options in regards to mercury. According to FDA recommendations, you can safely eat between two and three servings of salmon each week or one serving of sea trout, like steelhead trout.
What about the steelhead trout vs salmon price difference? While the cost you will pay for each type of fish can be influenced by a number of factors, including your location, the season, and demand, salmon tends to be more expensive than steelhead trout.
Of the varieties of salmon, sockeye and king salmon are among the most expensive, while pink and Atlantic are a bit cheaper.
