Summary

The Rainbow Trout is a cold-water salmonid native to rivers, streams, and lakes along the Pacific coast of North America and northeastern Asia. It is widely farmed, stocked for angling, and introduced to waters in many other regions. Cool, oxygen-rich water is important for wild populations, while managed strains are raised for food and sport.
