Grand Junction Fish and Wildlife Conservation Office

We use applied sciences and innovative technology to drive today’s management practices and enable the U.S Fish and Wildlife Service to work effectively with our partners to meet today’s complex conservation challenges. Grand Junction FWCO conducts research on the life history of four endangered Colorado River fish and the habitat that supports them. Knowledge of the biology of the fish and their ecological requirements is essential to understanding the threats these fish face and to developing management strategies for their recovery. Studies have included such subjects as timing and location of spawning, distribution and relative abundance of larvae and young-of-the-year, dispersal patterns of adults, seasonal habitat requirements, growth rate, survival rate, sex ratio and food habits.
