Michael R Childs, and Robert W Clarkson, Temperature effects of hypolimnial-release dams on early life stages of Colorado River Basin big-river fishes: .

Summary

Declines of native big-river fishes of the Colorado River Basin, southwestern United States, have been attributed in part to emplacement of hypolimnial-release dams. Lowered spring-summer tailwater temperatures inhibit spawning and embryonic development, depress swimming performance and growth, and reduce survival of early life stages. We examined effects of three temperatures (10 C, 14 C, 20 C) on aspects of growth, development, and physiology of larval and early juvenile life stages of Xyrauchen texanus (Razorback Sucker), Catostomus latipinnis (Flannelmouth Sucker), Gila cypha (Humpback Chub), and Ptychocheilus lucius (Colorado Squawfish) in the laboratory. Lengths, weights, and specific growth rates of all species were significantly [...]
