Rainbow Trout

Rainbow Trout

Rainbow Trout in Connecticut are an introduced species native to the Pacific Northwest, widely stocked throughout the state but with limited natural reproduction. Only one known self-sustaining population exists at Hubbard Brook in Hartland.

These coldwater fish prefer well-oxygenated lakes and streams, moving to faster, well-aerated areas as temperatures rise.

Rainbow Trout in Connecticut seldom survive summer conditions and rarely reproduce naturally, as domestic hatchery strains aren't well-suited for local spawning conditions.

Scientific Name: Oncorhynchus mykiss
