Over much of its range, Pugnose Shiner ( Notropis anogenus ) populations are isolated and endangered. This study tested the feasibility of pond culturing Pugnose Shiner for restoration. In 2015, 65 wild broodstock from Sodus Bay, New York State's last remaining Lake Ontario population, were stocked into a 0.2ha aquaculture pond. Thousands of juveniles were quickly produced, and during 2016–2017, 7,400 pond‐reared Pugnose Shiner were stocked into Chaumont Bay, Lake Ontario. Poststocking surveys in 2020 demonstrated the establishment of 4‐year classes in Chaumont Bay from natural reproduction. Following the successful establishment of Pugnose Shiner in Chaumont Bay, the New York State Department of Environmental Conservation recommended the downlisting of the Pugnose Shiner from Endangered to Special Concern. The restoration strategy described here is applicable to other sites in the United States and Canada, where this species is also of conservation concern.
