For years, there has been confusion surrounding the classification of steelhead trout. Until recently, Fisheries and Oceans Canada described steelhead as a type of Pacific salmon on their website. However, the current consensus is that steelhead are actually a type of trout. This confusion has led to debates among scientists and organizations about the proper classification of this unique fish.
A Trout that Behaves Like a Salmon
Steelhead trout, scientifically known as Oncorhynchus mykiss, shares the same species as rainbow trout. However, steelhead behave more like salmon than trout. They hatch in fast-flowing rivers and streams and can either stay in freshwater their whole lives or migrate into the ocean. Those that migrate to the ocean change color and grow much larger than resident rainbow trout. Similar to Pacific salmon, steelhead return to their birth rivers to spawn, although they don't necessarily die after spawning and some even return to the ocean.
Reshuffling the Family Tree
The classification of steelhead has been a subject of reshuffling in the scientific community. In the past, steelhead were referred to as Salmo gairdneri and placed next to Atlantic salmon on the tree of life. However, in 1989, scientists recommended a change in the taxonomy of steelhead, stating that the old name was an error. Today, the Pacific Salmon Foundation still lists steelhead alongside salmon, calling its classification a hotly debated topic.

Steelhead trout has gained popularity as a sustainable alternative to salmon. As overfishing of salmon has become a concern, chefs are turning to steelhead trout for its similar taste and sustainability.

The classification of steelhead trout as either salmon or trout may still be a subject of debate, but what's clear is that this fish offers a sustainable and delicious alternative to salmon. Its unique characteristics and versatility in cooking make it a favorite among chefs and seafood enthusiasts. As efforts continue to protect and conserve steelhead populations, it's important for governments and organizations to take action and ensure the future of this remarkable species.
