Regions:
* North America: The majority of trout species originate here, including rainbow, brook, and brown trout.
* Europe: Home to brown trout and other species.
* Asia: Many trout species are native to Asia, including the highly prized golden trout.
* Australia: Introduced species, like brown trout, are now common.
* New Zealand: Introduced species, including rainbow trout, have thrived.
Specific Habitats:
* Rivers and streams: Trout prefer flowing water, often with a gravelly bottom and plenty of hiding places.
* Lakes: Large lakes with cooler water temperatures are suitable habitats.
* Reservoirs: Some trout species can thrive in reservoirs, especially if they have a good supply of oxygen and food.
* High-altitude streams and lakes: Trout are often found in these environments, where the water is cold and clear.
Factors that Influence Trout Distribution:
* Water temperature: Trout are cold-water fish, and most species prefer temperatures between 40-65°F.
* Water quality: They need clean, well-oxygenated water.
* Food availability: Trout feed on insects, crustaceans, and smaller fish.
* Habitat structure: They need places to hide, such as rocks, logs, and vegetation.
Note: Introduced trout species can sometimes become invasive, disrupting the balance of native ecosystems. It's important to be aware of the potential impacts of introducing non-native fish species.
