Distribution and Habitat
The greater redhorse, Moxostoma valenciennesi, is a species of freshwater fish endemic to states in the northcentral and northeastern United States as well as Ontario and Quebec in Canada. It is typically found in clear, relatively fast-moving rivers and in both shallow and deep waters in some lakes. They are unable to survive in even the slightest polluted waters. They, therefore have the strong ability to detect contaminated water sources.
Physical Description
The greater redhorse is the largest fish in its genus, averaging around 46 cm (18 in) and 2 kg (4.4 lb) and reaching a maximum size of 80 cm (31.5 in) and 5.9 kg (13 lb). This species of fish have smaller eyes in comparison to their large rounded skull. The posterior part of the dorsal fin varies from straight to slightly convex. The greater redhorse is most easily identified by it's bright rusty red colored tail fin.
Diet Habits
A bottom-feeder's mouth opens in the inferior position of the ventral surface of the fish. It feeds on various bottom dwelling organisms including, microcrustaceans, aquatic and larval insects, detritus, snails, and algae.
Reproduction, Life Cycle
Spawning for the greater redhorse will begin in May or June. To build their gravel and sand nests, they locate an area in moderately fast waters. Once male territories are established, the females will visit two males at a time and begin their spawning process. Following fertilization, the greater redhorse eggs would hatch after six to eight days at a mean temperature of 19° C. Growth rates of this species are controversial among various parts of their habitats.
