Abstract

Catch per unit of effort in drifted trammel nets fished along the bottom in the main channel of Pool 9 was described. Multiple regression analysis indicated that variations in water temperature, current velocity, turbidity, or sampling periods accounted for significant variations in catch of four of the five most abundant species in the samples (Shovelnose sturgeon, Scaphirhynchus platorynchus; Quillback, Carpiodes cyprinus; Shorthead redhorse, Moxostoma macrolepidotum; Walleye, Stizostedion vitreum vitreum; and Freshwater drum, Aplodinotus grunniens).
