Salmon are among the most popular and widely recognized fish in the world, valued for their taste, nutrition, and ecological importance. Found mainly in the Pacific and Atlantic regions, these fish are known for their unique life cycle, migrating between freshwater and the ocean. There are many types of salmon, each with distinct features, habitats, and behaviors. In this guide, you will discover 27 types of salmon with their common names and key characteristics, helping you understand their differences and importance in both nature and fisheries.
1. Chinook Salmon
Chinook salmon is the largest and most valued salmon species, famous for its rich taste and high fat content. It is often called the “king” of salmon due to its size and importance in commercial and recreational fishing. This species is widely distributed across the Pacific Ocean and nearby river systems, making it one of the most recognized salmon types in the world.
Identification
- Large and robust body, often the biggest among salmon
- Blue-green back with shiny silver sides and white underside
- Small black spots on the back, dorsal fin, and tail
- Dark or black gums inside the mouth
Habitat
Chinook salmon live most of their adult life in the Pacific Ocean but return to freshwater rivers and streams to spawn. They are commonly found along the western coasts of North America and parts of Asia. Clean, cold, and fast-flowing rivers are essential for their breeding, as these environments provide oxygen-rich water needed for egg development.
Diet
Chinook salmon are active predators that feed on a variety of marine organisms. Their diet mainly includes smaller fish such as herring and anchovies, along with squid and crustaceans. In their juvenile stage, they consume plankton and aquatic insects. As they grow, their diet shifts toward larger prey, helping them gain the energy needed for long migrations.
Behavior
Chinook salmon are known for their anadromous life cycle, meaning they migrate from the ocean to freshwater to reproduce. They are strong swimmers and can travel long distances upstream against powerful currents. After spawning, most adults die, completing their life cycle and contributing nutrients back into the ecosystem.
Lifespan
The typical lifespan of Chinook salmon ranges from 3 to 7 years. Growth rate and survival depend on environmental factors such as food availability, water temperature, and migration challenges. Some individuals may live slightly longer, but most complete their life cycle within this time frame, returning once to spawn before dying.
2. Coho Salmon
Coho salmon is a popular and widely recognized species known for its bright color and firm, flavorful meat. It is smaller than Chinook but still highly valued in both commercial fisheries and recreational angling. Coho salmon are commonly found in the Pacific Ocean and nearby freshwater systems, especially along North America’s western coastline.

Pacific salmon are anadromous and known for their long migrations between ocean and freshwater. They have a strong homing instinct and return to their birthplace to spawn. After reproduction, most species die.
Lifespan
The lifespan of Pacific salmon varies by species but generally ranges from 2 to 7 years. They spend most of their life in the ocean before returning once to freshwater to spawn and complete their life cycle.
27. Farmed Salmon
Farmed salmon refers to salmon that are raised in controlled environments such as aquaculture farms. These are usually Atlantic salmon, bred for consistent supply, size, and quality. Farmed salmon plays a major role in meeting global seafood demand.
Identification
- Medium to large size depending on farming conditions
- Uniform body shape and smooth appearance
- Silvery coloration with fewer natural markings
- Often appears cleaner and more consistent than wild salmon
Habitat
Farmed salmon are raised in man-made environments such as sea cages, pens, or freshwater tanks. These systems are designed to control water quality, temperature, and feeding conditions to support growth and health.
Diet
Farmed salmon are fed a controlled diet that includes fish meal, fish oil, and plant-based ingredients. This balanced diet is designed to promote fast growth, maintain health, and ensure consistent flesh quality.
Behavior
Farmed salmon live in confined spaces and do not migrate like wild salmon. Their behavior is influenced by controlled feeding schedules and limited space, making them less active compared to wild populations.
Lifespan
Farmed salmon are typically raised for 2 to 3 years before harvest. Their growth rate is carefully managed to reach market size efficiently, ensuring a steady and reliable supply for consumers.
