Distribution
The Rainbow Trout is native to North America but has been introduced to other parts of the world including Europe, South America, and Oceania. Notable migration patterns include movement from freshwater spawning areas to the ocean, similar to other anadromous species.
Habitats
Rainbow Trout predominantly live in cold, freshwater bodies like rivers, streams, and lakes. They thrive in temperatures between 55 to 60°F (12-15.5°C), but can tolerate temperatures from 32 to 70°F (0-21°C), given suitable oxygen conditions.
When and Where to See
They are most commonly seen during spring and fall during spawning seasons. They are active throughout the day but are especially active during dawn and dusk.
