  	Citation × Citation Citation Abstract Copy Title: Federal Register - Endangered and Threatened Wildlife and Plants; Determination of Endangered Status of the Shortnose Sucker and the Lost River Sucker Author: Williams, Jack E. Year: 1988, 2008, 2005 The Service determines endangered status for the shortnose sucker [Chasmistes brevirostris) and Lost River sucker [Deltistes luxatus), fishes restricted to the Klamath Basin of south-central Oregon and north-central California. Dams, draining of marshes, diversion of rivers and dredging of lakes have reduced the range and numbers of both species by more than 95 percent. Remaining populations are composed of older individuals with little or no successful recruitment for many years. Both species are jeopardized by continued loss of habitat, hybridization with more common closely related species, competition and predation by exotic species, and insularization of remaining habitats. This rule implements the protection provided by the Endangered Species Act of 1973, as amended, for the shortnose sucker and Lost River sucker Title: Federal Register - Endangered and Threatened Wildlife and Plants; Determination of Endangered Status of the Shortnose Sucker and the Lost River Sucker Author: Williams, Jack E.

Year: 1994, 2005 PROGRESS REPORT FOR INVESTIGATIONS ON BLUE CREEK FT 1992 ABSTRACT The U.S. Fish and Wildlife Service, Coastal California Fishery Resource Office in Arcata, California, was funded to investigate chinook salmon roncorhvnchus tshawvtschav spavming use, juvenile salmonid emigration, and characterize stream habitats in Blue Creek, a tributary to' the Klamath River; California. Investigations began in October 1988, with this reporting period covering October 1991 through September 1992. Adult chinook spawner escapement was addressed by surveys of redds, live fish and carcasses, and by radioteleiretry. Spawner numbers were v?ry low, with only 22 redds observed in fall 1991/winter 1992. The peak count of adult Chinook was 97 fish in early November. Radiotelemetry of migrating spawners (n?8) was used to locate remote spawning areas. Emigrating juvenile Chinook salmon, steelhead trout 10. mvkissV/ coho salmon (fi. kisutchl. and coastal cutthroat trout (g. clarltiV were trapped at river kilometer (rkm) 3.35 with a rotary screw trap (screw trap). The trapping period extended from April to July for a total of 75 trapping nights. Screw trap catches totaled 10,688 chinook, 1,388 steelhead, 99 coho and 10 cutthroat. Peak Chinook emigration occurred during the week of May 17, which is consistent with the past 3 years of monitoring. A juvenile weir was operated 58 nights, and caught a total of 9,166 chinook, 1,196 steelhead, 127 coho and 1 cutthroat. The index of abundance for emigrating chinook during the 1992 juvenile trapping period was 49,590. Sixty-five percent of the juvenile chinook caught during the trapping season were marked with coded wire tags (n-12,687) and released back into Blue Creek at rkm 3.3. Mean water temperatures varied from 6.3 to 18.6 XI and stream flows ranged from 43 to 2178 eft (1.3 to 61.7 m3/?) during the Fiscal Year (FY) 1992 study season.

  	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.
