Description
- Abstract: This report summarizes spring Chinook salmon monitoring data for the Lower Snake River Compensation Plan (LSRCP) facilities in 2002. The main objectives of this report are to document and evaluate salmon culture performance for spring Chinook salmon hatchery programs and achievement of management objectives in the Imnaha and Grande Ronde river basins. These data are used to design culture practices to optimize egg-to-smolt survival rate, smolt quality, smolt-to-adult survival rate, and to provide information to adapt the programs to most effectively meet management objectives. This report provides information on rearing and release operations for the 2000 and 2001 cohorts of juvenile Chinook salmon, the collection, spawning and adult characteristics for the 2002 return of adult Chinook salmon, and the collection of eggs for the 2002 cohort.

- Purpose: LSRCP Chinook Salmon Program Objectives 1. Prevent extinction of Imnaha River, Lostine River, Catherine Creek, and upper Grande Ronde River Chinook salmon populations and ensure a high probability of population persistence well into the future, once causes of basin-wide declines have been addressed. 2. Establish adequate broodstock to meet annual production goals. 3. Establish a consistent total return of Chinook salmon that meets the LSRCP mitigation goal of 3,210 hatchery adults in the Imnaha Basin and 5,820 hatchery adults in the Grande Ronde Basin. 4. Re-establish historic tribal and recreational fisheries. 5. Minimize impacts of hatchery programs on resident stocks of game fish. 6. Operate the hatchery program so that the genetic and life history characteristics of hatchery fish mimic those of wild fish, while achieving mitigation goals. 7. Maintain genetic and life-history characteristics of natural Chinook salmon populations in the Imnaha River, Lostine River, Catherine Creek, and upper Grande Ronde River. 8. Maintain the genetic and life-history characteristics of the endemic wild populations of Chinook salmon in the Minam and Wenaha rivers. 9. Provide a future basis to reverse the decline in abundance of endemic Chinook salmon populations in the Imnaha and Grande Ronde river basins. Research Monitoring and Evaluation Objectives 1. Document Chinook salmon 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 Chinook salmon smolts. 3. Document Chinook salmon adult returns by stock to each LSRCP broodstock collection facility. 4. Estimate annual hatchery returns to compensation areas and determine success in meeting mitigation goals. 5. Estimate annual smolt survival to Lower Granite Dam for production and experimental groups. 6. Conduct index, extensive, and supplemental Chinook salmon spawning ground surveys for all populations in northeast Oregon to assess spawn timing and spawning distribution, and estimate natural spawner escapement. 7. Determine the proportion of naturally spawning spring Chinook salmon that are of hatchery origin in all Imnaha and Grande Ronde Chinook salmon populations. 8. Determine annual escapement and spawner numbers to estimate and compare productivity (recruits per spawner) for natural- and hatchery-produced fish in the Imnaha and Grande Ronde basin Chinook salmon populations. 9. Compare life history characteristics (age structure, run timing, sex ratio, egg size, and fecundity) of hatchery and natural origin salmon. 10. Coordinate Chinook salmon broodstock marking programs for Lookingglass Fish Hatchery. 11. Participate in planning activities associated with anadromous salmon production and management in the Imnaha and Grande Ronde river basins and participate in ESA permitting, consultation, and recovery planning.
