Description
- Abstract: The purpose of this progress report is to provide summary information for Lower Snake River Compensation Plan (LSRCP) summer steelhead programs operated by ODFW in the Grande Ronde and lmnaha river basins during 1999 and 2000. These ongoing monitoring programs provide technical, logistical, and biological information to managers charged with maintaining viable salmon and steelhead populations and associated fisheries in Northeast Oregon.
This report summarizes fish culture monitoring data for LSRCP facilities for summer steelhead. These data serve as the basis for the analysis of trends in culture performance. Generally speaking, the data in this report were derived from hatchery inventories and standard databases (i.e., PSMFC, Coded-wire tag) or through standard measuring techniques. As such, specific protocols are usually not described. In cases where expansions of data or unique methodologies were used, protocols are described in more detail. Additional descriptions of protocols can be found in the 1999 and 2000 work statements (Carmichael et al. 1999a, Carmichael and Ruzycki 2000). Coded-wire tag (CWT) data that were collected from 1999-2000 adult returns were used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 1999-2000, experimental treatments from which fish returned included acclimated vs. direct stream release, forced vs. volitional release, rearing site, growth, and density treatments. In 1999-2000, experimental treatments for which fish were released included forced vs. volitional, and pre-smolt release strategies. Analysis of specific survival studies will be completed once all brood years have returned and CWT data are complete for a given experiment. In addition, much of the data that we discuss in this report will be used in separate and specific evaluations of ongoing supplementation programs for steelhead in the Imnaha River basin. We began culture evaluations in 1983 and have dramatically improved many practices. Progress for work completed in previous years is presented in annual progress reports (Carmichael and Wagner, 1983; Carmichael and Messmer, 1985; Carmichael et al., 1986a, 1987, 1988a, 1988b, 1989, 1990, 1999b, 2004, 2005; Messmer et al., 1989, 1990, 1991, 1992, 1993; Flesher et al., 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1999; Whitesel et al., 1993; and Jonasson et al., 1994, 1995, 1996), United States v. Oregon production report (Carmichael et al., 1986b), and a five-year study plan (Carmichael 1989). Progress of related work completed in 1999 and 2000 is presented in summer steelhead creel annual progress reports (Flesher et al., 2000, and 2001), and in the steelhead life history, genetics, and kelt reconditioning 1997-2001 progress report (Ruzycki et al., 2003).
This report is organized into fish culture monitoring for juveniles, adults, CWT recoveries, and estimates for total escapement. During the period covered in this report, steelhead from the 1994-1997 broods returned to spawn, steelhead from the 1998 and 1999 broods were released as smolts, and adult steelhead that returned to spawn were used to create the 1999 and 2000 broods.
