Range extends over the North Atlantic from Russia and Labrador in the North to Portugal and Maine in the south. Largest populations are in Russia, Norway, Iceland, Canada, Ireland and of course Scotland.
Salmon breed in freshwater and the small fish enter the sea usually between 1 and 4 years old. They become adults after 1 to 4 years feeding in the Atlantic and grow to weights of between 2 and 30lbs.Then they return to the river and place of their birth to spawn another generation.
Some of the spawned fish return to sea where they recondition and repeat the process perhaps two or three times.
