<br />The remaining fish (2E, 3C, 6C, 8C, 12C, 13C, 14C, and 15C) all moved continuously <br />downstream and entered Lake Powell. <br />Individual Movements -Estimated Rates of Movements <br /> Only 17 of the 23 razorback suckers that were located following their release were <br /> contacted a sufficient number of times to estimate their daily rates (km/day) of movement <br /> (Figures 3A and 3B). Six razorback suckers (10E, 1C, 3C, 4C, I lC, and 14C) were <br /> located just twice during the 58 days of tracking. The remaining 11 fish were contacted <br /> between 3 and 7 times. The general trend was for the initial movement offish to be at a <br /> high rate of ~5 km/day and decrease over time to near 0 km/day. <br /> However three razorback suckers increased their estimated daily rate of movement over <br /> time. Fish l OE and 1 C increased their daily movements from ~3 km/day during the first <br />f <br />d <br />f <br />l <br /> ew <br />ays <br />o <br />lowing release to ~5 km/day by day 10. Contact was lost with both fish by <br /> day 12, so it will remain unknown if their rate of movement attenuated over time as <br /> occurred in the majority of the razorback suckers. Fish 2C, the third razorback sucker to <br /> have an increased daily movement rate over time, decreased its daily movements from <br /> ~5 km/day during days 1 to 8 to near 0 km/day during days 30 to 58. However, a burst of <br /> movement occurring during day 29 resulted in a positive slope (Figure 3B). <br /> The direction of the estimated daily movement rates for the suckers can also be seen in <br /> Figures 3A and 3B. Positive data points designate upstream movements, whereas <br /> negative data points designate downstream movements. Only two suckers with greater <br /> than two contacts increased their rate of downstream movement over time. As previously <br /> mentioned, fish 2C moved down the Green River and then up the Colorado River <br /> 24.9 km. Fish 2C then began a fairly rapid movement downstream and entered Lake <br /> Powell. This rapid, mid-study, downstream movement resulted in a negative slope for <br />2C's average directed rate of movement over the course of the study period. Fish SE also <br /> increased its rate of downstream movement over time. Fish SE moved out of the Green <br /> River in approximately 8 days traveling at ~8 km/day (Appendix 1). Fish SE then made a <br /> 55.8-km movement up the Colorado River between days 7 and 12 at ~12 km/day. <br /> Upstream movement continued at a reduced rate (~3 km/day) until day 19, at which point <br /> SE moved downstream at ~-7 km/day and contact was lost 4.8 km above the Green River <br /> confluence. This trend in daily movements from large upstream, to small upstream, to <br /> large downstream resulted in the trend of SE increasing downstream movements over <br /> time. <br />Individual Movements -Fish Condition Factor (K) <br />The movement patterns of razorback suckers did not a ear to be de endent u on the <br />PP P P <br />condition factor [K = (weight* 100/length3)]. Condition factors (K) ranged between 0.734 <br />and 1.057, and were not correlated with length (p = 0.97, regression analysis) but were <br />11 <br />1 <br />
