The scientific name of the brown trout is Salmo trutta. Global climate change risks affecting this species. S. trutta prefers well-oxygenated water in the temperature range of 16 to 18 °C. Cover or structure is important to trout. They prefer submerged rocks and logs, banks, and overhanging plants. Structure provides protection from predators, bright sunlight, and higher water temperatures. Trout need access to deep water for protection in winter lake freezes.
