The U.S. Fish and Wildlife Service has downlisted the razorback sucker from endangered to threatened, citing growth in fish populations that the agency says has reduced the risk to the species. The freshwater fish, which is native to the Colorado River and the Grand Canyon, was first listed in 1991 after dams on the river and other waterways in the Colorado River Basin fractured its habitat and created conditions that hampered its ability to reproduce. Non-native fish in the river also contributed to losses to the species. … The fish species still faces threats to its survival, the agency said, including changes in river flows and habitat, changes in water quality, drought and non-native species.
