Abstract

The Upper/Middle Rio Grande and Pecos rivers Area Report will provide an overview of research, monitoring, and recovery efforts for fishes of the region in 2022. This year’s accomplishments included: establishment of new populations of Rio Grande Chub Gila pandora and Rio Grande Sucker Catostomus plebeius, initiation of a rangewide genomics study of Pecos Pupfish Cyprinodon pecosensis, successful post-fire rescue efforts of populations of Rio Grande Cutthroat Trout Oncorhynchus clarkii virginalis and Chihuahua Chub Gila nigrescens, and continued long-term monitoring of Rio Grande Silvery Minnow Hybognathus amarus, Pecos Bluntnose Shiner Notropis simus pecosensis, and White Sands Pupfish Cyprinodon tularosa. Additional highlights will also be discussed; e.g., the discovery of Gray Redhorse Moxostoma congestum persisting in the Delaware River after an extended dry period, and the agency partnerships that have resulted in conservation actions to benefit Canadian River fishes.
