Salmon is the common name for several species of fish of the family Salmonidae . The fish is pink and silver. Several other fish in the family are called trout . Salmon live in both the Atlantic and Pacific Oceans , as well as the Great Lakes and other land locked lakes.
Typically, salmon are salt water fish. anadromous : they are born in fresh water , migrate to the ocean , then return to fresh water to reproduce . However, there are rare species that can only survive in fresh water habitats. This is most likely due to the domestication of these certain species of Salmon. Folklore has it that the fish return to the exact spot where they were born to spawn.
The red colour of salmon is due to a pigment called astaxanthin, naturally occuring carotenoit and present in their food items. In cultured fish it´s usually added to the fishmeal, otherwise the animals would be white.

back. A mature salmon has a long, thin body. Generally,
female salmon are larger than males. The largest salmon are
the Atlantic salmon and the chinook. The smallest is the pink
