Salmon facts are very informative and interesting for kids

Salmon are anadromous fishes, which means the adults return to their natal spawning ground and lay eggs in the freshwater stream.

After the young ones are born, the adults die.

The young ones then move to the sea and reside there for several years, where their body gains a lot of nutrients. When they reach their mating maturity they return back to the rivers in which they were born by trailing the scent of the freshwater.

These adult fishes are also called keystone species which means they bring a lot of nutrients from the sea during the spawning season and impact the river ecosystem to a great extent as a lot of animals and coastal plants including the decomposers benefit from them.

If you liked these true facts about salmon then you'll surely like these facts about rays and bull sharks too!

Where do salmon live?

Salmon live both in fresh water and in the ocean. Hence they are called anadromous (fish that migrate from time to time for reproductive purposes or other unlisted reasons).

They are usually born in freshwater but they soon migrate to the ocean after that. During reproduction, they are known to come back to  freshwater. However, there are certain species of salmon that do not migrate and hence are only restricted to freshwater.

Did you know...

Salmon fishing is considered a kind of recreational sport. However, commercial fishing is restricted in the ocean since it makes it difficult for the adult salmon family to return back to their natal spawning grounds, i.e., freshwater rivers. There are also issues regarding the salmon stock resources between commercial fishing and recreational fishing.

Atlantic salmon have been so extensively hunted that there is no such salmon left in the wild. Now there are only farm-raised salmon left in fisheries that are raised in net cages.

Wild Alaskan salmon hunt constitutes more than 80% of the total number of salmon caught which is the largest in North America from Canada and the Pacific Northwest. It is run by salmon fisheries in Alaska where they harvest many types of Pacific salmon.

Why are salmon a 'keystone species'?

Salmon are considered a keystone species since they have a great impact on the ecosystem, i.e., a lot of other animals are dependent on this species. The fish is also responsible for maintaining biodiversity.

When salmon leave their natal ground and go to the ocean, the body of the salmon gets rich in nutrients. During reproduction, when adult salmon come back to the freshwater spawning grounds, they carry a lot of nutrients in their body which they carry from the sea.

This greatly impacts the freshwater ecosystem as a lot of organisms in the rivers benefit from those nutrients.

Thus the spawning season proves extremely beneficial for the entire ecosystem. Not only the animals who feed on Salmons benefit from it but also the decomposers who feed on the dead salmons and the coastal trees and animals residing in that area.
