Table 7. Wilcoxon rank-sum comparisons of average catch rates (mean score of the number <br />caught per hour) for species caught by boat electrofishing in the Green River near <br />Tusher Wash Diversion Dam in 1998. Fish caught upstream from the dam are labeled <br />"Upstream", while fish caught downstream from the dam are labeled "Downstream". <br />Native species and significant differences (alpha =0.05) are shown in bold. Analyses <br />were conducted on 13 samples collected above the dam and 24 samples collected <br />below the dam. <br /> LOCATION <br />SPECIES <br />Upstream <br />Downstream Prob >_ S-Mean <br />bluehead sucker 23.69 16.46 0.0517 <br />Colorado pikeminnow 11.85 22.88 0.0014 <br />flannelmouth sucker 20.35 18.27 0.5878 <br />Gila spp. 24.54 16.00 0.0007 <br />speckled dace 15.92 20.67 0.1788 <br />black bullhead 17.77 19.67 0.3843 <br />channel catfish 14.61 21.38 0.0719 <br />common carp 12.50 22.52 0.0061 <br />fathead minnow 18.12 19.48 0.6727 <br />green sunfish 16.50 20.35 0.1398 <br />red shiner 16.23 20.50 0.1285 <br />sand shiner 14.00 21.71 0.0104 <br />walleye 18.00 19.54 0.5315 <br />21 <br />
