About the Edition

The distribution and abundance of large (660mm MEF) chinook salmon Oncorhynchus tshawytscha that returned to spawn in the Stikine River above the U.S./Canada border in 1997 were estimated by means of radio telemetry and a mark-recapture experiment. Age, sex, and length compositions for the immigration were also estimated. Drift gillnets fished near the mouth of the Stikine River were used to capture 731 immigrant chinook salmon during May, June, and July, 1997; 702 of these fish were marked with spaghetti tags, opercle punches and axillary appendage clips, and 255 also had radio transmitters inserted into their stomachs. During July and August, chinook salmon were captured at spawning sites and inspected for tags. Marked fish were also recovered from Canadian commercial, test and aboriginal fisheries. Using a modified Petersen model (M = 653, C = 4,528, R = 93) we estimated that 31,509 (SE = 2,960) large chinook salmon immigrated to the Stikine River above Kakwan Pt. Canadian fisheries on the Stikine River harvested 4,513 large chinook salmon, which left an escapement of 26,996 large fish. The total count at the Little Tahltan River weir was 5,557 large chinook salmon, about 20% of the estimated spawning escapement. We used weir counts and a foot survey to estimate an escapement of 478 large fish in Andrew Creek. From the radio telemetry study, we estimated that 17.7% of the spawning chinook salmon went to the Little Tahltan River, 17.5% to the Iskut, 4.7% to the Chutine, 3.5% to the Christina, 25.8% to the Tahltan, 21.8% to upper Stikine, 7.2% to lower Stikine and 1.8% to U.S. tributaries. An estimated 2% of the Kakwan Point gillnet catch was age -1.2, 26% age -1.3, 70% age -1.4, and 1% age -1.5; 232 males and 352 females were captured. An estimated 3% of spawning ground samples were age -1.2, 24% age -1.3, 72% age -1.4, and 0.4% age -1.5; 323 males and 438 females were sampled.

SUMMARY A fall-run chinook salmon Oncorhynchus tshawytscha escapement survey was conducted in the upper Sacramento River during fall-winter to acquire data on spawner abundance, age and sex composition of the spawner population, pre-spawning mortality and temporal and spatial. Prior toChinook salmon escapement was measured with peak aerial survey counts in nine index streams and there were no formal escapement goals.

Beginning ina mainstem mark-recapture project was initiated by the Alaska Department of Fish and Game to estimate total inriver abundance of Chinook salmon in the Copper River. able data on the distribution and abundance of other fish species.

A few stud-ies have focused primarily on the resident fishes. The purpose of this paper is to compile and analyze data available through for chinook salmon and other fish species occurring in the lower Tuolumne River. The salmon data are.

Figure 5 Annual fall-run chinook salmon escapement to the American River, natural and hatchery contribution Figure Feather River Escapement As on the American River, the escapement to the Feather River was strong. Similarly, the entire production from the Feather River Hatchery is trucked to near Carquinez Strait for release.

The only group of chinook with the proper qualifications to serve as a mid-coast stock ERI was the Elk River hatchery stock. The catch distribution shown in Figure 1 is more similar to the adjacent stocks of the Coos, Coquille, and Umpqua rivers than is.

The goal of the Umpqua Escapement Indicator Project is to precisely estimate the annual escapement at age of adult chinook salmon to the Umpqua River, and to annually update a brood-year reconstruction for that stock.

These data will be the basis for a stock-recruitment analysis necessary to estimate a biologically-based spawner escapement goal.
