Common Name: bigscale logperch
Identification: Sturgess (1976); Page (1983); Sublette et al. (1990); Hubbs et al. (1991); Page and Burr (1991).
Size: 11 cm.
Native Range:
From Sabine River, Louisiana, and Red River, Oklahoma, to Rio Grande drainage, Texas, New Mexico, and Mexico (Page and Burr 1991). Stevenson and Thompson (1978) reviewed the distribution of this species.
Nonindigenous Occurrences: This species was originally introduced into the Sacramento River drainage in Miller, Blackweld, and Polk lakes on Beale Air Force Base, Yuba County, California in 1953 (McKechnie 1966c; Moyle et al. 1974). It is established in the Sacramento-San Joaquin basin as well as in Silverwood, Pyramid, Castaic, and Irvine lakes in southern California and the Lower Sacramento drainage since 1988 (Moyle et al. 1974, Moyle 1976a; Page and Burr 1991; Swift et al. 1993; Sommer et al. 2001). Collected in and Yolo Bypass (Sommer 2001). This species is also established in California in the Del Valle Reservoir, Tulare-Buena Vista, Suisun Bay, and Antelope-Fremont Valleys drainages (Moyle et al. 1974; Moyle and Randall 1999; Matern et al. 2002). Although the species was reported as P. caprodes (Ellis 1974; Wiltzius 1985), it was actually P. macrolepida that was introduced into Two Buttes Reservoir, Baca County, Colorado (Behnke, personal communication via S. Flickinger). The bigscale logperch has also been introduced into Ute Reservoir in Quar County, New Mexico (Sublette et al. 1990). Cashner and Matthews (1988) suspected that this species was introduced into several sites in Oklahoma, including the Washita River in Custer County, the North Canadian River in Woodward County, Fort Supply Lake in Woodward County, and possibly into Lake Optima in Texas County (Cashner and Matthews 1988).
Means of Introduction: Unintentional. The bigscale logperch was introduced into California with contaminated stock from the Trinity River, Texas, in 1953 (Moyle 1976a; Dill and Cordone 1997). These introductions were carried out by the U.S. Fish and Wildlife Service during intentional stocking of largemouth bass and bluegill (McKechnie 1966c). This percid subsequently entered the Del Valle Reservoir, Alameda County, California, via the Tracy pumping plant and the South Bay Aqueduct (Farley 1972; Moyle et al. 1974a; Dill and Cordone 1997). It was introduced by bait bucket into New Mexico (Sublette et al. 1990). The Colorado introduction was the result of stock contamination of fishes transplanted from Texas prior to 1952 (Ellis 1974; Wiltzius 1985).
Status: Established and expanding in California. Since its original introduction, the bigscale logperch has extended its range southward into the San Joaquin drainage (Farley 1972; Dill and Cordone 1997); and northward into the Yuba, Sacramento and Feather rivers (Boles 1976). Established in New Mexico, and presumably in Oklahoma. Probably extirpated in Colorado. Two Buttes Reservoir has been periodically dry since 1979 (C. Bennett, personal communication).
Impact of Introduction: Largely unknown. The species reportedly feed on eggs of centrarchids (Moyle et al. 1974a).
Remarks: Lee et al. (1980 et seq.) considered the Washita River, Oklahoma population to be native. They did not map the other Oklahoma sites. Specimens from Lake Optima, Oklahoma have not been positively identified but are reportedly logperch and well outside the native range of both P. caprodes and P. macrolepida (Cashner and Matthews 1988). Prior to 1976 many authors including Shapovalov et al. (1959), McKechnie (1966c), Farley (1972), and Moyle et al. (1974a), referred to introductions of this species and reported them as P. caprodes. Since that time P. macrolepida was described and has been split from P. caprodes. Sturgess (1976) determined the species in California was actually P. macrolepida and not P. caprodes. Moyle et al. (1974a) provided a map showing the range of the bigscale logperch in California and Dill and Cordone (1997) gave an overview of the species' history in that state.
