Appearance and Physical Characteristics

Streamlined, torpedo-shaped body for fast swimming.
Silvery scales in the ocean; may turn reddish or darker during breeding season.
Strong tail (caudal fin) to swim against powerful river currents.
Sharp teeth for catching prey.
Gills to breathe underwater.

Salmon have a special ability called osmoregulation, which allows them to adjust their bodies when moving from salty ocean water to fresh river water.

Did You Know? Some salmon develop a hooked jaw called a “kype” during breeding season. This helps males fight for mates.

Salmon Habitat and Distribution

Found in the North Atlantic and North Pacific Oceans.
Live in cold, clean freshwater rivers and streams during early life.
Spend most of their adult life in the ocean.
Return to the exact river where they were born to lay eggs.

Salmon habitat must have cool temperatures and clean water. Pollution and warming waters can harm salmon populations.

Salmon Diet and Feeding Habits

Young salmon eat plankton and small insects.
Adult salmon eat smaller fish, shrimp, and crustaceans.
They are carnivores.
Use speed and sharp eyesight to catch prey.

In the food chain, salmon are both predators and prey. They are eaten by bears, eagles, seals, and even humans.

Behaviour and Lifestyle

Known for long-distance migration.
Excellent swimmers that can leap over waterfalls.
Usually travel in groups during migration.
Use smell to find their birth river.

Salmon Life Cycle

Egg Stage: Eggs are laid in freshwater rivers.
Alevin: Hatchlings stay in gravel and feed from a yolk sac.
Fry: Young fish begin swimming and feeding.
Smolt: Body adapts to saltwater before moving to the ocean.
Adult: Grows in the ocean and later returns to freshwater to reproduce.

Did You Know? Many Pacific salmon die after laying eggs, but Atlantic salmon may survive and return to the ocean again.

What Makes Salmon Special?
