Colorado pikeminnow can live up to 40 years and were historically known to grow to nearly 6 feet long and weight 80 pounds. Today, researchers commonly see adult Colorado pikeminnow that are 2 to 3 feet in length.
Colorado pikeminnow are known for long-distance spawning migrations of more than miles in late spring and early summer. They are capable of reproducing at 5 to 7 years of age. Young Colorado pikeminnow feed on insects and plankton, whereas adults feed mostly on fish.
The Colorado pikeminnow was a valued food source by early settlers. Dale Stewart of Vernal, Utah, caught a pound Colorado pikeminnow in This fish also readily strikes lures and live bait used to catch sport fish or nonnative fish. Status and distribution Listed as endangered by U.
Listed as endangered under Colorado law in ; status changed to threatened in Protected under Utah law since Today, two wild populations of Colorado pikeminnow are found in the Upper Colorado River Basin — one in the upper Colorado River system and one in the Green River system.
The Colorado pikeminnow is adapted to warm rivers and requires uninterrupted passage and a hydrologic cycle characterized by large spring peaks of snowmelt runoff and lower, relatively stable base flows.
Working to recover the species Actions being taken to recover the Colorado pikeminnow include: Fragmentation refers to separation between fish populations caused by geographical distance or physical barriers.
Essential habitats, including primary migration routes and required stream flows are legally protected.
