Abstract
Few studies have attempted to characterize microhabitat use by cyprinids, particularly over a broad temporal scale. In this study, I quantified the physical in-stream characteristics of habitat use by the redside dace, Clinostomus elongatus using a one-square meter spatial scale. These characteristics were delineated in four Ohio streams that contained substantial populations of redside dace. Individual redside dace locations within the study site were recorded, along with stream velocity, depth, proximity to woody debris, and distance to the edge of the wetted stream channel, seasonally throughout the study. Redside dace positions within the stream were found to be non-random in relation to most variables and seasons. Generally, redside dace oriented toward positions with slower current velocities (0.00-0.08 m/s observed versus 0.00-0.19m/s based on randomization sampling), greater depths (0.33-0.84m observed versus 0.07-0.35m random), closer to woody debris (0.00-1.61m observed versus 0.53-5.64m random), and further from the edge of the wetted stream channel (0.60-1.93m observed versus 0.17-0.71m random). From this study it is clear that redside dace are drawn to particular habitat features. Additionally, there were some differences observed for the different seasons which may be important for the persistence of populations over time. During winter they stayed closest to woody debris (average of cells with redside dace present for all sites during winter 0.32m; spring 0.86m; summer 0.55m; fall 0.78m). In spring they used areas that were shallower (spring 0.53m; summer 0.60m; fall 0.58m; winter 0.69m) and with higher velocities (spring 0.05m/s; summer 0.01m/s; fall 0.03m/s; winter 0.03m/s) because of spawning activities in riffles and runs. These differences in microhabitat use would have been missed if this study had not covered a time span of a full year.
