The salmon group includes salmons, trouts, whitefishes, and graylings. These fishes can be more than 5 feet (1.5 meters) long and weigh more than 100 pounds (45 kilograms). Salmons have streamlined bodies that are covered with small, smooth scales. Salmons have a small adipose (AE-dih-POS) fin between the dorsal (DOOR-suhl) fin, or the fin along the midline of the back, and the powerful tail fin.

Salmons live in the Northern Hemisphere.

Many salmons spawn, or release eggs, in freshwater and migrate (MY-grayt), or move, to the sea to mature. Some salmons spawn near the ocean shore and have no real freshwater phase. Others never leave freshwater.

Some salmons eat plankton, or microscopic plants and animals drifting in bodies of water, and bottom-dwelling invertebrates (in-VER-teh-brehts), which are animals without a backbone. Other salmons eat other fishes.

Salmons are important commercial and sport fishes.
