Southwest Region, November 19, 2004
Print Friendly Version
During autumn 2004, New Mexico Fishery Resources Office and cooperating agencies (New Mexico Department of Game and Fish, FWS-R6 Fisheries, Navajo Nation Fish and Wildlife Departement and volunteers, Bureau of Indian Affairs)conducted 4 sampling trips to remove and transplant nonnative channel catfish from the San Juan River. The removal efforts, part of the San Juan Recovery Implementation Program, serve to remove competing/predating nonnative species from habitats occupied by federally endangered Colorado pikeminnow and razorback sucker. The channel catfish, some weighing up to 10 lbs., are provided to Navajo Nation and State managed recreational fisheries isolated from the San Juan River. During the four trips, 2,412 channel catfish were removed and 90% of those stocked in Navajo Nation and State of New Mexico waters. Concurrent to the nonnative sampling, important data were recorded for 30 Colorado pikeminnow and 74 razorback suckers captured during these efforts.
