Trout belong to the salmonidae family. One differentiates between sea, lake and brown trout according to their habitat and body form. Lake trout prefer oxygen-rich lakes. In the spawning period they leave this habitat and wander up into the tributaries to lay their eggs. They mainly feed on several types of crab and smaller fish. Lake trout have a torpedo-like, flattened body and live a mere four to six years.
Brown trout are more likely to be found in cold and flowing waters. Characteristic of the rainbow trout is a bright red ribbon, stretching along the sides of their body allowing them to be clearly recognised. Moreover, their fins are sprinkled with numerous spots.
Due to its appearance the brown trout can adapt very well to their environment and is a master of camouflage. Like the rainbow trout it feeds mainly on insects, snails and worms. The brown trout grows to a length of up to 60 centimetres and the rainbow trout can reach a stately 70 centimetres and can weigh up to seven kilograms.
Rainbow trout were originally saltwater fish, however today they are also at home in freshwater breeding.
