Abstract:
The desert pupfish (Cyprinodontidae, Cyprinodon macularius (Baird and Girard 1853)) is the only fish endemic to the Salton Sink. There are two subspecies in the United States: a Colorado River form (C. m. macularius Baird and Girard) and a Quitobaquito form (C. m. eremus Miller and Fuiman) (Marsh and Sada 1993). This report focuses on C. m. macularius, whose wild populations occur around the Salton Sea (Marsh and Sada 1993). Information was obtained from a literature search conducted by the California Department of Fish and Game (CDFG), an internet search, and from the library at the Bureau of Reclamation in Denver, Colorado. Recent unpublished survey data were obtained from CDFG. Desert pupfish were once widespread and abundant in portions of southern Arizona and southeastern California, United States, and northern Baja California and Sonora, Mexico (Miller 1943). In 1859, Girard first reported desert pupfish in California in some saline springs in Imperial County (Jordan, Evermann, and Clark 1930). After the Salton Sink was flooded in 1904-1907 by diversion of the Colorado River, desert pupfish colonized what is now known as the Salton Sea (Thompson and Bryant 1920) and was reported as "abundant" by several authors (Coleman 1929; Cowles 1934; Barlow 1958, 1961; Walker 1961). However, only Barlow (1961) provided an estimate of 10,000 individuals in a single shoreline pool of the Salton Sea. Collections made by CDFG and others, including Schoenherr (1979), in the late 1950s to early 1960s indicated that desert pupfish abundance at the Salton Sea was severely declining (Black 1980). In surveys conducted by CDFG in 1978-1979, desert pupfish accounted for 3 percent of the total catch in irrigation drains, 5 percent of the catch from shoreline pools, and less than 1 percent of the catch from three natural permanent tributaries and the Salton Sea proper (Black 1980). However, desert pupfish accounted for 70 percent of the total catch from San Felipe Creek, an intermittent tributary to the Salton Sea. The desert pupfish was listed as a California endangered species in1980 (CDFG 1980). The U.S. Fish and Wildlife Service (FWS) listed this species and its critical habitat as endangered in 1986 because of habitat alteration, introductions of exotic species and contaminants, and other habitat impacts (FWS 1986). Designated critical habitat includes San Felipe Creek, Carrizo Wash, and Fish Creek Wash in Imperial County, California (FWS 1986). Figure 1 shows the general distribution of desert pupfish around the Salton Sea. Current desert pupfish populations occur in drains directly discharging to the Salton Sea, in shoreline pools of the Salton Sea, several artificial refugia, and in desert washes at San Felipe Creek and Salt Creek. Pupfish are not known to occur in the New or Alamo Rivers because of the high sediment loads, excessive velocities, and presence of predators (Imperial Irrigation District 1994).
