What Is Steelhead Trout?

Steelhead Trout, also known as Oncorhynchus mykiss, is a type of rainbow trout that is native to the West Coast and Alaska. It is an anadromous fish that hatches in rivers and streams and spends most of its life in the ocean before spawning to freshwater. Steelheads have a flavor and appearance similar to Salmon, though they are not the same species.

They are a popular sport fish in North America, with an impressive ability to adapt to different environments. Steelhead Trout are known for their perplexing behavior, making them a challenge for anglers.

What Is Salmon?

Salmon is an iconic species of fish that is native to both the North Atlantic and Pacific Oceans. It has a characteristic orangey-pink flesh and is popular among humans as a food source. Salmon are anadromous, meaning they live in fresh and saltwater, making them unique. They are born in freshwater, where they spend a few months before migrating to the sea.

Seven Pacific salmon species and one Atlantic salmon are commercially important. Smoked Salmon is a popular preparation of this fish, which can also be eaten raw or cooked in various ways. Salmon is rich in protein and omega-3 fatty acids, making it a nutritious and delicious addition to any meal.

Why Is Steelhead Called Salmon?

Steelhead trout is not a salmon but a type of trout belonging to the same family of salmonids. It is native to cold-water tributaries of the Pacific basin in Northeast Asia and North America and is named after its metallic, almost transparent head coloration. Steelhead has similar characteristics to other Pacific salmon, except for one major difference – they are repeat spawners, unlike other Pacific salmon. Steelhead’s meat is pink like the Salmon’s and is more flavorful than the light-colored flesh of the trout. Steelhead is farmed primarily in British Columbia and Chile and is one of the top sport fish in North America.

How To Tell The Difference Between Steelhead Trout And Salmon?

Steelhead trout and Salmon may look alike, but some key differences in their appearance are worth noting. To tell them apart, you’ll need to consider size, color, fat content, mouth shape, and spawning behavior.


  • Steelhead Trout Size:  Steelhead trout tend to exhibit a substantial size range, with variations depending on factors such as location, diet, and age. Their length can vary from about 19 to 45 inches (48 to 114 cm). In terms of weight, they typically range from 8 to 55 pounds (3.6 to 25 kg). However, it’s worth noting that some exceptional specimens have been recorded to exceed 40 pounds (18 kg) in weight.
  • Salmon Size: Salmon, on the other hand, can also be found in various sizes, but they generally tend to be slightly larger than steelhead trout. Depending on the species and region, the average length of Salmon is typically between 18 and 39 inches (45 to 99 cm). They generally weigh between 8 and 50 pounds (3.6 to 22.7 kg), with exceptional Salmon weighing over 60 pounds (27 kg) not being uncommon.


1. Differences in color patterns

Steelhead trout and Salmon possess distinct color patterns that can help differentiate between the two species. While both exhibit variations in coloration, some key differences are evident.

Steelhead Trout: Steelhead trout have a silvery appearance with a dark blue or greenish hue on their backs. They typically feature small black spots on their bodies and tails, which become more pronounced as they mature. Additionally, steelhead trout may display a reddish or pinkish stripe along their lateral line, extending from the gills to the tail.

Salmon: Salmon, on the other hand, display a wider range of color patterns, depending on the specific species and life stage. Among the most common are silver, blue, or greenish shades on the back, transitioning into a lighter or white belly. Some salmon species, such as Chinook or King Salmon, may exhibit black spots on their back, tail, and upper body. Others, like sockeye salmon, boast a rich red body color that intensifies during the spawning season.

2. Camouflage Techniques Used by Each Species

  • Steelhead Trout: The silvery hue of steelhead trout helps them blend into the open water, making it difficult for predators to spot them. This coloration allows them to maintain a level of stealth while migrating along rivers and coastal areas. The darker coloration on their backs can also provide some camouflage against rocky river bottoms and shadowy areas.
  • Salmon: Salmon exhibit more diverse color patterns, which can be attributed to their various environments throughout their lifecycle. For instance, when Salmon is in the ocean or large bodies of water, their silver or blue-green coloration assists in blending with the surrounding water and evading predators. However, when they return to freshwater to spawn, their colors often change to more vibrant and conspicuous shades. This transformation is believed to help males establish dominance and attract mates during spawning.

Steelhead trout and Salmon possess distinct color patterns and employ different camouflage techniques. The silvery appearance and small black spots are characteristic of steelhead trout, whereas Salmon exhibit a broader spectrum of colors, featuring variations such as silver, blue, green, or red. The different coloration strategies of these two species contribute to their survival in their respective habitats.

Migration Patterns

When it comes to migration patterns, there are distinct differences between Steelhead Trout and Salmon. First, it is important to understand the concept of anadromous versus non-anadromous fish.

Anadromous fish, like Steelhead Trout, have a unique migration pattern that involves moving from freshwater rivers to the ocean during certain life cycle stages. Once in saltwater, they spend several years growing and maturing before returning to their original freshwater spawning grounds to reproduce. This migration cycle can be quite lengthy and can cover vast distances.

On the other hand, Salmon also exhibit anadromous behavior, but their migration patterns tend to be more direct and predictable. They tend to return to the specific river or stream where they were born to spawn, often traveling hundreds or even thousands of miles to reach their destination. Unlike Steelhead Trout, Salmon are known for their strong homing instinct and rarely deviate from their natal streams.

Furthermore, it is worth mentioning that some Steelhead Trout populations are non-anadromous, meaning they do not migrate to the ocean. These non-anadromous Steelhead Trout, often referred to as “resident” or “rainbow trout,” spend their entire lives in freshwater environments. Unlike their anadromous counterparts, they do not undertake the long and perilous journey to the ocean and back.

While both Steelhead Trout and Salmon are well-known for their remarkable migration patterns, they differ in the extent and complexity of their journeys. Steelhead Trout exhibit a more diverse range of migration strategies, including both anadromous and non-anadromous behaviors, while Salmon display a highly specialized homing instinct that directs them back to their exact place of birth.

Differences In Spawning Habitats

Steelhead trout and Salmon are known for their impressive migration patterns, but they have some differences in their spawning habitats. Firstly, steelhead trout are anadromous fish, which means they spawn in freshwater but spend a significant portion of their lives in saltwater. On the other hand, Salmon are also anadromous, but some species complete their entire life cycle exclusively in freshwater, while others migrate to the ocean before returning to freshwater to spawn.

When it comes to specific spawning locations, steelhead trout, and Salmon also differ. In freshwater, steelhead trout tend to spawn in smaller streams and rivers with suitable egg incubation conditions. They typically choose gravel beds with moderate water flow for successful reproduction. Salmon, on the other hand, have more specific spawning preferences. For example, Chinook salmon prefer large, deep rivers with gravel bottoms, while coho salmon tend to gravitate towards smaller streams and tributaries.

In saltwater, steelhead trout can be found in nearshore areas close to river mouths, estuaries, and even out in the open ocean. They spend a significant portion of their lives here, feeding and gaining strength before they return to freshwater to spawn. Conversely, salmon migrate to the open ocean, where they spend most of their adult lives. They venture far out to sea, feeding on various marine organisms, and then return to freshwater to reproduce in the specific locations mentioned earlier.

These differences in spawning habitats between steelhead trout and Salmon highlight the flexibility and adaptability of both species. While steelhead trout are capable of utilizing a wider range of freshwater and saltwater environments throughout their life cycle, Salmon has more specific requirements for successful spawning. Understanding these differences helps us appreciate these two magnificent fish’s diversity and unique characteristics.

Feeding Habits

Their diet consists of small fish, insects, crustaceans, and aquatic invertebrates. Steelhead Trout are skilled hunters, using their strong lateral lines and excellent eyesight to locate their prey. Once they spot their target, they employ swift and agile movements to capture it. This hunting technique makes them efficient predators in their aquatic environment.

On the other hand, Salmon also have an eclectic diet, but it usually revolves around their life stages. Young Salmon primarily feed on insects, plankton, and small aquatic organisms. As they mature and migrate to the ocean, their diet expands to include larger fish and marine invertebrates. Salmon are known for their exceptional ability to detect chemical cues in their environment, allowing them to sense the presence of prey even in murky waters. Once they locate their target, they use their sharp teeth and powerful jaws to seize and consume it.

While Steelhead Trout and Salmon are skilled predators with diverse diets, Steelhead Trout tend to exhibit more flexibility in their prey choices. They rely on their lateral lines and visual acuity to hunt efficiently, while Salmon possesses a remarkable ability to perceive chemical cues in their environment to track and capture their prey. These subtle differences in feeding habits contribute to each species’ unique characteristics and behaviors.
