Fluctuating water levels may have a detrimental effect on Golden Redhorse populations. Deacon (1961) found that in Arkansas, abundance of Golden Redhorse was directly related to stream conditions affected by drought, becoming scarce in the lower mainstream when flow increased. Meyer (1962) suggests that based on evidence presented by Hall and Jenkins (1953) and Finnell et al. (1956), the formation of reservoirs on rivers could have adverse effects on redhorse populations. One factor involved in maintenance of Golden Redhorse populations may be the accessibility of smaller streams for spawning and nursery habitat (Harlan and Speaker 1956). Trautman(1981) also reports that Golden Redhorse ascend the smaller streams in spring. Yet, in a study of the seasonal movement of Golden and Black redhorses in Ohio, no significant differences were found between average distances moved in the spring as compared to the fall, nor were any mass seasonal movement patterns exhibited (Smith 1978). Young Golden Redhorses have been described from varying habitats. Meyer (1962) and Larrimore et al. (1952) found young fish inhabitating slow-moving waters over soft- bottoms in areas near overhanging river banks. whereas Cooper (1983) found juveniles on riffle margins in moderate current. In contrast, Martin and Campbell (1953) found that, in Missouri, young Golden Redhorse inhabited the deeper, faster waters of streams near riffle areas. The complexities of proper identification of Moxostoma erythrurum, combined with difficul- ties in determining optimum habitat, precludes making definitive statements regarding protection of suitable habitat in Canada.
