Also summarized are the associated broodstock monitoring data collected at weirs in the Grande Ronde Basin that are operated by our co-managers, the Nez Perce Tribe (NPT; Lostine River) and Confederated Tribes of the Umatilla Indian Reservation (CTUIR; Catherine Creek and Upper Grande Ronde River). The main objectives of this report are to document and evaluate spring-sumer Chinook Salmon culture performance for hatchery programs and achievement of management objectives in the Imnaha and Grande Ronde river basins (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 separate reports prepared by each co-management agency). Overall, these data are used to adaptively manage salmon culture practices in order to optimize egg-to-smolt survival rate, smolt quality, smolt-toadult survival rate, the recruits-per-spawner (R:S) ratio, and to monitor spawning in nature by hatchery-reared salmon.

We set 66 static gill nets for an average 1.0 hand captured no green sturgeon and 8 individual white sturgeon (114-181 cm FL). We deployed 17 seine nets for an average 0.1 hand captured no sturgeon. We deployed the underwater camera 21 times for 0.1-0.8 hand observed no sturgeon. Unmarked sturgeon were tagged with spaghetti and passive integrated transponder (PIT) tags. Field staff from Oregon Department of Fish and Wildlife's Gold Beach office sampled green sturgeon in the Rogue River. Fifty unmarked green sturgeon (136-197 cm FL) were captured in gill nets and one unmarked green sturgeon was captured angling (147 cm FL). Forty-eight of the unmarked sturgeon were tagged with spaghetti tags and 47 were tagged with PIT tags. Of these, 5 were recaptured once and 1 was a recapture from the previous year. Thirty-five fish were radio tagged, sonic tagged, or both. One juvenile green sturgeon (17-cm TL) was captured during beach-seine sampling. We interpreted ages of 27 green sturgeon from pectoral fin-spine sections collected by Oregon Depar,tment of Fish and Wildlife, Columbia River Management staff during Oregon coastal estuary sampling and estimated parameters of Von Bertalanffy growth functions using these and previously collected data.
