Where does salmon come from?

Salmon come from both freshwater and saltwater environments. They are anadromous fish, meaning they are born in freshwater rivers and streams, then migrate to the ocean to grow and mature, and finally return to their natal rivers to spawn.

Here's a more detailed breakdown:

* Freshwater: Salmon eggs are laid in gravel nests (called redds) in rivers and streams. They hatch into fry and stay in freshwater for a period of time, developing into parr.

* Saltwater: Once they reach a certain size, salmon migrate to the ocean, where they spend most of their adult life feeding and growing.

* Return to Freshwater: After a few years, salmon begin their journey back to the freshwater rivers where they were born. This is known as the "spawning migration". They use their sense of smell to find their way back to their natal streams.

* Spawning: Once they reach their spawning grounds, they lay eggs and die.

Types of Salmon:

There are several different species of salmon, each with its own distinct characteristics and geographical range. Some of the most common types include:

* Atlantic Salmon: Found in the North Atlantic Ocean, including rivers in North America and Europe.

* Pacific Salmon: Found in the Pacific Ocean, including rivers in North America, Asia, and Russia. This group includes Chinook, Sockeye, Coho, Pink, and Chum salmon.

Salmon Farming:

A significant portion of the salmon consumed comes from salmon farms. These farms raise salmon in enclosed areas, either in the ocean or in freshwater tanks.
