Table 2. Number of fish caught in drift nets set in the Green River and in the Green River <br />Canal during sampling conducted from May 5-26, 1998, and from June 29, 1998, <br />through August 22, 1998. The column labeled "Volume" shows the amount of water <br />sampled at each site: Species are abbreviated as follows: CS: Colorado pikeminnow, <br />CH: chub (unidentified Gila species), SD: speckled dace, BH: bluehead sucker, FM: <br />flannelmouth sucker, FH: fathead minnow, CC: channel catfish, SS: sand shiner, RS: <br />red shiner, CP: common carp, WS: white sucker, NNC: non.-native cyprinid <br />(unidentified species). Abbreviations and values for native species are shown in bold <br />italic print. <br />Location Volume <br />(m'') CS CH SD BH FM FH CC SS RS CP WS NNC <br />Green River 31,564 12 6 74 17 2 1 18 0 1 2 0 3 <br />Canal 26,689 1 1 25 9 6 4 21 1 3 1 1 3 <br />Table 3. Wilcoxon rank-sum comparisons of catch rates (mean score of the number caught per <br />cubic meter of water sampled) for species caught in drift nets set in the Green River <br />and in the Green River Canal during 1998. Native species and significant differences <br />are shown in bold. Analyses were conducted on 200 samples from the Green River <br />and 139 samples from the Green River Canal. <br /> Location <br />SPECIES <br />Green River <br />Canal Prob >_ S-Mean <br />bluehead sucker 169.58 170.61 0.08080 <br />Colorado pikeminnow 172.97 165.73 0.0309 <br />Gila species 171.25 168.20 0.2613 <br />flannelmouth sucker 168.70 171.88 0.1734 <br />speckled dace 173.78 164.57 0.1124 <br />common carp 170.20 169.71 0.7135 <br />channel catfish 168.20 172.59 0.3534 <br />fathead minnow 168.36 172.36 0.1633 <br />non-native cyprinid <br />(species unidentified) 170.05 169.92 0.7218 <br />red shiner 169.35 170.94 0.4708 <br />sand shiner 169.50 170.72 0.4100 <br />white sucker 169.50 170.72 0.4100 <br />15 <br />
