Salmon are widely known as species of the family Salmonidae. They live along the coasts of Pacific Ocean and the North Atlantic Ocean. Salmon are also called as anadromous as they spend most of their lifetime in the ocean and will only return to fresh water to spawn.
Freshwater streams supply important natural environment for many salmon species. While they are young, they feed on earthbound and aquatic insects and other shellfish or parasites. Salmon eggs are placed in deeper water with larger pebbles where its need good water flow and suitable cool temperatures to supply oxygen to develop embryos. In the early life stages of the salmon, its mortality is usually high due to its predation and changes in global such as siltation, low oxygen concentration, high water temperatures, loss of stream cover and reductions in river flow.
As they grow bigger and older, salmon’s skin color will completely change from the silvery blue to a darker color. The salmon normally spend between one to five years in the open ocean before they become sexually mature. The mature salmon will return to their natal stream fresh water to spawn. Salmon is an amazing fish of which sometimes can travel or swim hundreds of miles upstream against the strong currents and rapids to reproduce. Prior to the spawning, salmon grows a hump and develop canine teeth while a male salmon develops a pronounced curvature of the jaws.
