	Citation Citation Citation Abstract Copy Title: Annual report, Klamath River fisheries assessment program : juvenile salmonid trapping on the mainstem Trinity River at Willow Creek and on the Klamath River at Big Bar, 1990 Author: Craig, James L. Year: 1992, 2005 ABSTRACT This report details the third year of Klamath River basin juvenile salmonid fishery investigations and represents the second year of sampling with rotary screw traps. Two traps, positioned side to side, were used at both the Klamath and Trinity River sites. The traps on the Klamath River were located at Big Bar (rkm 81) and began operation in March. The traps operated until July 10 and 18 sampling 38 and 31 nights respectively. Combined catch included 333 chinook (Oncorhynchus tshawytscha) , 178 steelhead (O^ mykiss) , and 30 coho (O^ kisutch) . No appreciable difference in mean catch or mean fork length of catch between the two traps was found. Peak weekly chinook catch effort, as an indicator of peak emigration, occurred the week of June 18 to 24. A total of five (1.5%) Ad-clip chinook were captured. A contribution of 134 (40%) hatchery chinook and 199 (60%) natural stock chinook was estimated for the total chinook captured. Mean migration rate for IGH Ad-clip chinook was 5.
