A total of 7724 fish were VIE tagged during this study, among these were 1505 Arkansas River Shiner, 5462 Plains Minnow, 757 were Peppered Chub. A total of 129 fish were recaptured after tagging and release. Twenty-one Arkansas River Shiner were recaptured at distances of 13.3- to 213.6-km upstream from the release site. Across all recaptures, including those from an earlier 2009-2010 study, the average rate of movement by Arkansas River Shiner, over a one-year period, is estimated to 0.42 km d-1 . Forty-four Plains Minnow were recaptured in this study. Twenty-eight of these were recaptured at the release site and 16 were captured 13.3- to 213.6-km upstream from the release site. Across all recaptures, the average rate of movement by Plains Minnow, over a one-year period, is estimated to 0.34 km d-1 . Sixty-six Peppered Chub were recaptured in this study. Sixty-three of these fish were recaptured at the release site and three were captured 13.3- to 51.7-km upstream from the release site. No estimate of annual movement of Peppered Chub is possible based on study data. The distance moved by recaptured Arkansas River Shiner, Plains Minnow, and Peppered Chub, combined is estimated to be 0.37 km d-1 , which serves as a general model of movement for small-bodied Great Plains broadcast-spawning fish. Survival of Arkansas River Shiner ova was not affected by absence of turbulence in high turbidity treatments in an experimental study. However, at more moderate turbidities, ova survival was reduced by a lack of turbulence. Turbidity increases the density of water and, hence, the buoyancy of ova. Thus, in high turbidity waters, ova may stay suspended until hatching regardless of the presence of flowing water, or settle slowly enough that they do not become completely buried. At lower, turbidities ova are more likely to be buried by settling v sediments in the absence of current. Mean specific gravity of Arkansas River Shiner ova ranged from 1.0058 to 1.0105, thus they are only slightly negatively buoyant. Specific density of larvae (days 1-, 3-, and 5-posthatch was greater that of ova, suggesting a need for current to keep larvae suspended in the water column. Comparison of catches of Arkansas River Shiner, Plains Minnow, and Peppered Chub during 2013 to 2014 showed these species had survived the drought of record in 2011 and that catch rates were comparable to those observed during an earlier six-year study. However, one species, Flathead Chub, which was common, but not abundant in 1996 to 2002, was absent from collections made during 2013 to 2014. It is possible Flathead Chub has become extirpated from this portion of the Canadian River. Although recent catch rates of Arkansas River Shiner, Plains Minnow, and Peppered Chub are comparable to those observed in 1996 to 2002, mean wetted channel width decreased at each of the three sites sampled monthly by at least 75%, suggesting populations of Arkansas River Shiner, Plains Minnow, and Peppered Chub have decreased by a comparable amount.
