Trout thrive in oxygen-rich water and watercourses where the temperature is not too high. Trout that grow up in watercourses where they can migrate to the sea will often do so, and are then referred to as sea trout.
Distribution:
Along the European Atlantic coast from Portugal in the south to the White Sea in the north. Inland trout are naturally distributed in Europe, North Africa and Northwest Asia
Food:
