fish for mink food from 1930 until 1950. According to his records on the Gunnison, he took 50 squawfish and a large number of Razorback suckers in one of the better years (Ralph Vernon, Personal Communication, 1976). Table 1 presents a summary of data collected in the five Gunnison River sampling areas.- These five sampling sections are shown graphically on Figure f. i" A rating of relative abundance of each fish species shown in Table 1 reflects the best expert judgement of N.F.R.I. on the present status of Gunni- son River fishes. The most common large species of fish captured during this segment of the study in order of decreasing numbers were: F-lannelmouth sucker, Blue- head sucker, and Roundtail chub. No federally classified endangered fish species were captured. Razorback suckers classified as endangered by the state of Colorado were observed in the lower reaches of the study near Grand Junction. Also, a Razorback sucker was taken from the Gunnison River in 1975 near Delta, Colorado. With exception of the Colorado Squawfish and Razorback sucker, the other native species of fish are faring quite well in the Gunnison River. It must be noted here that N.F.R.I. does not consider the Gunnison River as historic habitat for the B onytail or fi.umpback chubs. Many of the exotic or introduced fish species were found to be abundant to common in all sampling sections. The smaller species such as dace, shiners and minnows are the most numerous introduced species now found in the Gunnison River. Game fish such as trout were found only in the uppermost section near Delta, while catfish were considered common only in the lowermost section near Grand Junction. Age-growth data for fish in the Gunnison River near Delta is presented in Table 2. (13)
