-35- Bluehead suckers were also taken at the mouth, and upper section of Fontanelle Creek, the Black°s Fork River and in Henry's Fork River at the Highway 530 bridge crossing. All specimens were taken by electro-fishing gear. Sculpin (Coitus bairdi) This fish is very common throughout the entire drainage. It is found in practically every part of the study area having a gravel or rubble bottom. All tributaries to the Green River, except Sage Creek, produced .specimens of this fish. Rocky Mountain Whitefish ~ ~Coregonus williamsoni williamsoni) The whitefish is found primarily from the vicinity of-Big Island upstream. It seems to prefer the rubble bottom and clearer waters in this area although one specimen was taken just below the Flaming Gorge .Canyon. This fish, and the brown trout, provide the majority of game fish taken by fishermen within the study area. The only tributary in the study area in which whitefish .were found was Fontanelle Creek. During shocking operations at the mouth of Sheep Creek, one fish seen momentarily was thought to be a whitefish, but unfor- tunately it passed beyond the electrical field and recovered before it could. be captured. The whitefish taken in gill nets during this study ranged in size from 6.8 inches to 12.3 inches, and the average size was 8.6 inches. O'tah Silversides Minnow - Gila baleatus hydrophlox) This fish was found in moderate to heavy concentrations in tributary streams of the Green ,River. It was found throughout the length of the Big Sandy River from Highway 187 downstream, in the Black's Fork River upstream as far as the Highway 30 bridge crossing, and in Henry's Fork six miles above Highway 530 bridge crossing. :Although no specimens were-taken in the Green River proper during this study, it is felt that this species is present _ in the Green River, at least in the. vicinity of the mouths of the above men- tioned tributaries. Simon, 1946, reports that Silversides spawn near the Little Colorado Bridge in late June and early July. The Little Colorado Bridge is located on the Green .River proper, and is the site of Station No. 2 of this study. Brown Trout m (Salmo trutta fario) The brown is the predominate species of trout in the Green River from_ LaBarge downstream. A check on past planting discloses that 90.7% of all -- f ish planted in the Green River below LaBarge since 1939 have been brown trout. Specimens were collected as far downstream as the Big Island Bridge, Station No. 3 of this report. Evidence that brown trout do exist in the Green River below the town of Green River has been found, The use of toxicant at the mouth of Sage Creek Apr©duced a brown trout approximately 3 inches long. This fish was t'Y~c~ught to be the result of natural reproduction in the river, since the last plant made in the river was in 1954 and some b0 miles upstream
