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. 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. Redhorses are broadly of conservation concern, as these long-lived species are highly intolerant to environmental pollution, habitat fragmentation, and are currently subject to unregulated 21st century sport bowfishing which is removing and wantonly wasting several of these species by the ton.
