- Here are the four beautiful long-lived, big-river, warmwater endangered fish The Colorado pikeminnow , is the largest “minnow” in North America. Historically, reached 6 feet long They were sometimes called “Colorado River salmon,” of the Colorado river. The razorback sucker 3 feet, and living up to 40 years or more. The humpback chub with pronounced hump can grow up to 19 inches long and is typically found in canyon-bound reaches. The bonytail can grow up to 20 inches long and live as long as 50 years. Historically, these fishes occurred throughout the warmwater reaches of the basin from Wyoming to Mexico
- The threats to the endangered fish populations are the many changes to their habitat: Hundreds of dams river flows have been cut by about a third Introduced nonnative fish
- The recovery programs continue to demonstrate tangible, on-the-ground success in providing river flows, restoring habitat, constructing and operating fish ladders and screens, producing and stocking endangered fish, and monitoring results.
