Rio Grande Cutthroat is found in New Mexico and Southern Colorado.
One of 14 subspecies of cutthroat trout native to the western United States.
Occupies 150 miles of stream on the Santa Fe National Forest; only 15% of its historical range.
According to U.S. Wildlife Service, 13 core populations remain in the world. Core populations are the key to the survival of the species. Four core populations reside on the Santa Fe National Forest.
Typically spawn between middle of May and the middle of June.
Evolved in New Mexico as a member of a native fish assemblage that included longnose dace, Rio Grande chub and Rio Grande sucker.
Males are sexually mature at age 2; females at age 3; will live on average of five years; in rare cases, cutthroat trout have been known to enter their teens.
They feed opportunistically on aquatic insects and terrestrial insects that fall into the water.
