Moxostoma

Moxostoma, the redhorses or jumprocks, is a genus of North American ray-finned fish in the family Catostomidae. Redhorses are variable in size, geographic location, and other ecological traits such as spawning substrate.[1][2][3] Several redhorses are long-lived (lifespans greater than 20 years), much like many other catostomid species. The silver redhorse is the longest-lived redhorse known by nearly a decade, with ages exceeding 40 years.[1] Redhorses are broadly of conservation concern, as these long-lived species are highly intolerant to environmental pollution,[4] habitat fragmentation,[4] and are currently subject to unregulated 21st century sport bowfishing which is removing and wantonly wasting several of these species by the ton.[1]
