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 Imnaha river basins during 1997 and 1998. 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 1997 and 1998 work statements (Carmichael et al. 1997, 1998). Coded-wire tag (CWT) data that were collected from 1997-1998 adult returns are used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 1997-1998, experimental treatments from which fish returned included acclimated vs. direct stream and forced vs. volitional release strategies. In 1997-1998, experimental treatments for which fish were released included density treatments, forced vs. volitional release, rearing site, and growth treatments. 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.

-
- Purpose: 1. Document summer steelhead rearing and release activities at all LSRCP facilities. 2. Determine optimum rearing and release strategies that will produce maximum survival to adulthood for hatchery-produced summer steelhead smolts. 3. Document summer steelhead adult returns by stock to each LSRCP broodstock collection facility. 4. Determine if the total production of summer steelhead adults meet mitigation goals and index annual smolt survival and adult returns to Lower Granite Dam for production groups. 5. Participate in planning activities associated with anadromous fish production and management in the Grande Ronde and Imnaha river basins and participate in ESA permitting, consultation, and rearing activities. 6. Monitor natural spawning of summer steelhead in selected areas within the Grande Ronde Basin. 7. Determine the number of summer steelhead harvested annually and angler effort in recreational fisheries on the Grande Ronde, Wallowa, and Imnaha rivers.
