The predatory threat of invasive and large-bodied piscivorous taxa such as smallmouth bass in the upper Colorado River basin is substantial. For example, based on results of a bioenergetics model, Johnson et al. (2008) ranked smallmouth bass as the most problematic invasive species because of their high abundance, habitat use that overlaps with most native fishes, and ability to consume a wide variety of life stages of native fishes (Bestgen et al. 2008). Expanded populations of piscivores such as smallmouth bass are a major impediment to conservation actions aimed at recovery efforts for the four endangered fishes in the upper Colorado River basin: Colorado pikeminnow Ptychocheilus lucius, razorback sucker Xyrauchen texanus, humpback chub Gila cypha, and bonytail Gila elegans (U.S. Fish and Wildlife Service 2002a, b, c, d).
