ANNUAL RUN-SIZE, HARVEST AND SPAWNER ESCAPEMENT ESTIMATES FOR TRINITY RIVER BASIN CHINOOK AND COHO SALMON AND STEELHEAD (Continued)
1. Tag and recapture operations for adult spring- and fall-run chinook and coho salmon, and fall-run steelhead being conducted in the Trinity River basin should be continued during the 1991-92 migration season, using the capture sites near Willow Creek and Junction City.
2. The experiment to estimate the non-response rate for non-reward and $10-reward tags should be continued by tagging samples of chinook and coho salmon, and steelhead with $20 reward tags.
3. We should apply $10-reward tags to fall-run chinook and coho salmon, and steelhead at the JCW to estimate angler harvest rates of those species upstream of JCW.
