The Brook Trout is a vibrantly colored member of the Salmonids. It is indigenous to the north-eastern part of North America but was introduced to Europe and other parts of the world at the end of the 19th century. It prefers cold water streams and rivers and is a formidable predator, feeding on insects, leeches and small fish. The species is characterized by a brown or olive body with bright yellow or red spots on the sides and white fin contours.
