The world of salmon is a vast and wondrous place, full of different species, each with its unique characteristics and traits. Two of the most popular species of salmon are silver salmon and coho salmon. While they may seem like two distinct types of fish, the truth is that they are actually one and the same. In this article, we will delve into the world of silver salmon and coho salmon, exploring their similarities and differences, and uncovering the mystery behind their dual identities.
A Brief History of Salmon Nomenclature
Before we dive into the specifics of silver salmon and coho salmon, it’s essential to understand the history behind their names. The term “salmon” is derived from the Latin word “salmo,” which was used to describe a variety of fish that were similar to the modern-day salmon. Over time, as different species of salmon were discovered, they were given different names to distinguish them from one another.
In the case of silver salmon and coho salmon, the names were given to them by different groups of people. The term “coho” is derived from the Native American word “koho,” which was used by the indigenous peoples of the Pacific Northwest to describe a type of salmon that was known for its silver color. On the other hand, the term “silver salmon” was given to this species by European settlers, who were impressed by its shiny silver scales.
The Science Behind Silver Salmon and Coho Salmon
So, what exactly is the difference between silver salmon and coho salmon? From a scientific perspective, there is no difference between the two. They are both members of the same species, Oncorhynchus kisutch, and are genetically identical.
The reason why they are given different names is due to the different stages of their life cycle. Silver salmon are typically caught in the ocean, where they are known for their bright silver color and robust flavor. Coho salmon, on the other hand, are often caught in freshwater rivers and streams, where they are known for their distinctive red color and rich flavor.
Physical Characteristics
Despite their different names, silver salmon and coho salmon have many physical characteristics in common. They are both medium-sized fish, typically ranging in length from 20 to 30 inches and weighing between 8 and 12 pounds. They have a streamlined body shape, with a silver color that gradually fades to a pinkish-red color as they mature.
One of the key differences between silver salmon and coho salmon is their snout shape. Silver salmon have a more pointed snout, while coho salmon have a more rounded snout. Additionally, coho salmon tend to have a more pronounced hump on their back, which is a characteristic that is often used to distinguish them from other species of salmon.
Culinary Differences
While silver salmon and coho salmon may be the same species, they have some distinct culinary differences. Silver salmon are known for their mild flavor and firm texture, making them a popular choice for grilling and broiling. Coho salmon, on the other hand, have a richer flavor and a softer texture, making them well-suited for baking and poaching.

What is Silver Salmon?
Silver salmon, also known as coho salmon, is a species of salmon that is native to the Pacific Ocean and is widely distributed throughout the coastal waters of North America and Asia. It is a medium-sized fish, typically growing to 20-30 pounds in weight and 2-3 feet in length. Silver salmon are known for their distinctive silver color with a pinkish-red tint on their sides and belly.
Silver salmon are anadromous fish, meaning they migrate from saltwater to freshwater to spawn. They are born in freshwater rivers and streams, migrate to the ocean where they grow and mature, and then return to their natal spawning grounds to reproduce. Silver salmon are an important food source for many marine mammals, birds, and humans, and are also a popular sport fish.
What is Coho Salmon?
Coho salmon is another name for silver salmon. It is the same species of fish, and the terms “silver salmon” and “coho salmon” are often used interchangeably.
