Description
- Abstract: This report summarizes fish culture monitoring data for Lower Snake River Compensation Plan (LSRCP) facilities for each species. These data should 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 1995 and 1996 work statements (Carmichael 1995, 1996). Coded-wire tag (CWT) data that were collected from 1995-1996 adult returns is used to evaluate smolt-to-adult survival rates in experimental rearing and release groups. In 1995-1996, experimental treatments from which fish returned included acclimated vs. direct stream for steelhead and size-at-release for both steelhead and Chinook. In 1995-1996, experimental treatments for which fish were released included size-at-release, exercise, acclimation, and low density treatments for Chinook, acclimated vs. direct stream for both steelhead and Chinook, and forced vs. volitional release for steelhead. 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 both steelhead and Chinook in the Imnaha River basin.

- Purpose: 1. Document spring Chinook salmon and 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 spring Chinook and summer steelhead smolts. 3. Document Chinook salmon and summer steelhead adult returns by stock to each LSRCP broodstock collection facility. 4. Determine if the total production of spring Chinook and summer steelhead adults meet mitigation goals and index annual smolt survival and adult returns to Lower Granite Dam for production groups. 5. Coordinate spring Chinook broodstock marking programs for Lookingglass Fish Hatchery. 6. 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. 7. Conduct index, extensive, and supplemental spring Chinook salmon spawning ground surveys in selected streams in Northeast Oregon. 8. Identify hatchery and wild origin for carcasses collected on spawning ground surveys in the Grande Ronde Basin. 9. Monitor natural spawning of summer steelhead in selected areas within the Grande Ronde Basin. 10. Determine the number of summer steelhead harvested annually and angler effort in recreational fisheries on the Grande Ronde, Wallowa, and Imnaha rivers.
