Fisheries investigations were undertaken in the spring of 1978 (28 April to 25 June) in the Athabasca and Clearwater rivers upstream of Fort McMurray. The major objectives of the studies were to determine what spring spawners utilized these sections of the Athabasca and Clearwater rivers; to locate and describe their spawning grounds; and to describe the timing of spawning, hatching, and emergence in relation to environmental factors such as water temperature, turbidity, dissolved oxygen concentrations, and stream flow. Large numbers of longnose suckers spawned during mid May in the Athabasca River from Fort McMurray upstream to the Cascade Rapids, the same area used by fall spawning lake whitefish. The major concentrations were located just below the Mountain and Cascade rapids. There was no evidence of major spawning concentrations of this species elsewhere in the present study area. Shortly after spawning, longnose suckers left the project study area and presumably returned to the Peace-Athabasca Delta.
