  Citation × Citation Citation Abstract Copy Title: Lower Snake River Compensation Plan; Oregon Spring Chinook Salmon Evaluation Studies - 2010 Annual Progress Report Abstract -- This annual progress report summarizes spring Chinook salmon monitoring data collected by ODFW for the Lower Snake River Compensation Plan (LSRCP) facilities in 2010. Also summarized are the associated adult broodstock monitoring data collected in the Grande Ronde Basin by our co-managers, the Nez Perce Tribe (NPT) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR). The main objectives of this report are to document and evaluate spring Chinook salmon culture performance for hatchery programs and achievement of management objectives in the Imnaha and Grande Ronde river basins (Our co-managers, CTUIR and NPT, have specific program goals for Chinook returns to Catherine Creek, the Upper Grande Ronde River, Lookingglass Creek, and the Lostine River, that are discussed and evaluated in reports prepared by each co-management agency). Overall, these data are used to modify culture practices, as needed, in order to optimize egg-to-smolt survival, smolt quality, and smolt-to-adult survival rate, and track spawning in nature by hatchery-reared adults. This report provides information on rearing and release operations for the 2008 brood year of juvenile Chinook salmon smolts, the collection of eggs for the 2010 brood year, numbers and characteristics of adult Chinook salmon in the 2010 return year, the 2010 spawning year at Lookingglass Fish Hatchery and in nature, recruit summary and age composition of the 2005 brood year, and bacterial kidney disease (BKD) monitoring.

In recent years the Grande Ronde River was open to spring chinook angling however, due to limited harvest allotments, managers declined to open this fishery in 2016. Daily bag limits for all fisheries were two adipose fin-clipped chinook adults and five adipose fin-clipped jacks per day, with two daily limits in possession. Anglers were required to cease angling if they had retained a daily limit of marked adults.

We cover the period from initiation of the program in the late 1970s through the late 1990s, when significant hatchery reform measures were implemented in response to ESA listing and other policy influences. Separate papers are presented that review the recent performance of the Upper Grande Ronde River, Catherine Creek and the Lostine River Spring Chinook hatchery programs. The Grande Ronde basin historically supported diverse and robust populations of Chinook salmon Oncorhynchus tshawytscha. Abundant runs supported tribal and recreational fisheries throughout the basin. The recreational fisheries closed in the mid-1970s due to the depressed status of the populations and limited tribal fishing occurred from the mid-1970s - 1990s.

We compared run timing based on arrival time at the weir and found that naturally reared Chinook salmon arrived earlier than hatchery-reared fish in all 16 years. Carcasses of naturally reared fish of either or both sexes were recovered on the spawning grounds earlier than carcasses of hatchery-reared fish for all years combined and during 5 of 16 years, indicating earlier spawning by naturally reared fish. We compared spawning distribution using the percent of female carcasses recovered in each spawning ground survey reach. The percent recovery of the carcasses of naturally reared females was greater in reaches above the weir than below the weir and these carcasses were farther upstream than those of hatchery-reared females. For females of hatchery origin, carcasses were more commonly found in reaches closer to and below the weir (the smolt release location). Alternate management strategies designed to improve the maintenance of genetic integrity and life history characteristics of the Imnaha River Chinook salmon population should be considered, implemented, and evaluated. Collection strategies should be modified to ensure that the hatchery broodstock is representative of the entire natural run, and release strategies should be developed to promote a spawning distribution of hatchery adults that mimics the distribution of natural imnaha Chinook salmon.

We compared run timing using arrival time at the weir and found that natural salmon arrived earlier than hatchery salmon in 12 of 14 years. Natural carcasses, of either or both sexes, were recovered earlier than hatchery carcasses for all years combined and during 6 of 14 years, indicating earlier spawning by natural salmon. We compared spawning distribution using the percent of female carcasses recovered in each spawning ground survey reach. A greater percent of natural female carcasses were recovered in reaches above the weir and further upstream than carcasses of hatchery-reared females, which were more commonly found in reaches closer to and below the weir. Management strategies designed to maintain the genetic integrity and life history characteristics of the Imnaha River Chinook salmon should be considered, implemented and evaluated. Collected broodstock should mimic the wild run and spawn timing. Release strategies should be developed to promote a broader spatial spawning distribution of returning hatchery adults.
