There are two large families of salmon. The first is the Atlantic or European salmon (Salmo salar), which is found in the waters of the Atlantic and the Baltic Sea, and in the rivers of France, Scotland, Norway and the north of Spain. The other variety is called the Pacific salmon, and its flesh is drier and pinker.
