New Mexico, reintroduct-ion of the species bark into waters from wh.ic.h they have been extirpated, and dissemination of public information. Region 2 (Albuquerque) of the U.S. Fish and Wildlife Service has been especially active in :implementing the reintroduct ion sections of several of these recovery plans (,Johnson 1980, 1985). This paper reports on efforts to reintroduce Colorado squawfish (Ptychoche.ilus lucius) and woundfin (Plagotperus argentissimus) into tributaries of the Gila River in central Arizona. Squawf.ish have been extirpated from the Gila River basin since 1950 ("liller 1961) and woundfin since prior to the turn of the century (Minck.ley 1973). Recovery plans for both species recommend re intro ductiuns in the Gila River basin (USFWS 1978,}985). Additional. reintroductions of native fishes into southwestern oz;tors have been re}x~rted by Kepner and Brooks (1983) Eor Gila topm.innows (Poec•il:iops.is occidentalis), Johnson (1985) for rawrback suckers (Xyrauchen texanus), Rinne, et al. (1981) for Apache trout (Salmo apache), and Hobbs (1963, 1980) for Big Bend gambusia (Gambusia gaigei) and Leon Springs pupfish (Cyprlnodon bovinus).
