Native fish on the Missouri National Recreational River (MNRR) are relatively productive and dominated by cool and warmwater species, including catfish, sauger, suckers, and naturally reproducing populations of paddlefish. Fisheries are significant but different in species composition and total number from the pre-dam Missouri River.
Problems & Issues Affecting MNRR Fisheries
The mainstem dams have affected fisheries in other ways. The dams have controlled flooding, making development possible in the old erosion zone near the river, which was the best fish and wildlife habitat. While native fish numbers have declined, invasive alien species such as bighead and silver carp thrive, usurping much of the remaining habitat and food supply.
