<br />Colorado squawfish were taken on g and 9 August and measured 9 and 10 mm TL <br />respectively. <br /> <br />The 26 seine collections contain 262 fish (an average of 10 specimens per collection <br />received) representing 7 species. Minnows (4 species) account for 16% and suckers <br />(3 species) 84% of all fish. Native species (3 minnows and 2 suckers) account for <br />99% of the fish. Percentage composition for species representing at least 1 % of the <br />fish collected is 80% bluehead sucker, 12% chub, 4% flannelrnouth sucker, 3% <br />speckled dace, and 1 % fathead minnow. One Colorado squawfish was taken on 5 <br />September and measured 17 mm TL. <br /> <br />(3) Flaming Gorge Collections. <br /> <br />(a) Nursery Habitat Seine Collections, Desolation Canyon (and Gray Canyon), Middle <br />Green River, Utah, 14 June-18 September 1994 (counts, measures, cataloging, and <br />report completed from FY 96). <br /> <br />This set consists of the preserved portions of 470 nursery habitat collections for Green <br />River miles 213.8 to 131.7 taken during 14 June through 18 September, 1994 (694-01 <br />to 994-71B). The specimens have been cataloged (LFL 28935-30528) and are stored <br />as part of the Larval fish Laboratory Collection for voucher and future study (e.g., <br />identification of humpback chub). <br /> <br />In all, the collections received contain 150,131 preserved fish (an average of319 <br />specimens per collection) representing 15 species (page 61). Cyprinids account for <br />99.4% of all fish in these preserved collections. The more abundant preserved fishes <br />(those representing >0.5%) are red shiner (82%), fathead minnow (16%), and sand <br />shiner (1 %). Of the non-cyprinid fish, 837 are catostomids, 23 centrarchids, six <br />ictalurids, and one salmonid. <br /> <br />Native species account for 0.8% of all preserved fish. Of these, 70% are catoslomids <br />and 30% cyprinids, each family represented by three species. Of the native fish 42% <br />are bluehead sucker, 27% flannelrnouth sucker, 18% speckled dace, 9% Colorado <br />squawfish, 4% chub, and 1 % razorback sucker (including three tentatively identified <br />specimens). <br /> <br />Most preserved fish (77%) were collected in August and September. During those <br />months the relative rank of the more abundant fishes remains the same as for overall <br />collections. However, the more abundant fishes in June collections are red shiner <br />(94%), fathead minnow (3%), flannelmouth sucker (1 %), and bluehead sucker (1%) <br />and in July red shiner (80%), fathead minnow (14%), bluehead sucker (1 %), speckled <br />dace (l %), and sand shiner (1%). Preserved flannel mouth sucker effectively <br />disappear after June and bluehead sucker nearly so after July. The relative abundance <br />of red shiner decreases and that of fathead minnow and sand shiner increases from <br />June through August, then all reverse trend in September collections. <br /> <br />16 <br />
