摘要: Abstract Overwinter habitat use of shovelnose sturgeon Scaphirhynchus platorynchus in the Kansas River was determined by radiotelemetry from November 1996 to March 1997 at water temperatures 2–9°C. Eighty percent locations were depths 1.0–2.0 m, where current velocities 0.01–1.11 m/s surface and 0.02–0.79 bottom. Depths fish positively related discharge (r = 0.47, P 0.0001; r 0.60, 0.0001, respectively); bottom not significantly correlated 0.08, 0.31) with discharge. Water depths, velocities, temperature (P > 0.05). Ninety-two over sand substrate. Inside-bend macrohabitats used proportion their abundance 0.05), whereas channel crossovers greater than availability ≤ 0.0...
