Abstract

Least chub (Iotichthys phlegethontis) are small cyprinids endemic to the Bonneville Basin of Utah. Historically, they were scattered throughout the Bonneville Basin in a variety of habitats including Utah Lake, Provo River, Sevier River, Beaver River, streams and freshwater ponds near the Great Salt Lake, and springs and marshes scattered throughout central and southern Utah (Fig. 1; Sigler and Sigler 1996). Several populations of least chub have become extinct over the last century because of habitat loss and the introduction of nonnative species. Currently, least chub are found in only 9 isolated spring pools in the central and west desert regions of Utah (Perkins et al. 1998).
