Oregon Challenges
• Sea Lion predation at Willamette Falls.
• Naturally spawning hatchery fish.
• Residual hatchery fish.
• Introgression.
• Tributary overshoot in the Columbia.
• Monitoring steelhead abundance and
productivity.
?
Evaluating Wild Steelhead Harvest
• New wild steelhead harvest fisheries proposed
in three coastal sub-basins as part of Coastal
Multi-species Conservation and Management
Plan (CMP).
• Two implemented last year with goal of
keeping harvest <10%.
Salmon River Fishery
• ODFW committed to
evaluating impact.
• Small coastal basin with
good steelhead habitat.
• Basin-wide redd surveys
to estimate spawner
abundance.
• Creel to assess fishery.
Salmon River Fishery
• Open Dec. 1 through March 31.
• Primarily bank angling.
• Bag limit: 1 per day, 3 per year.
• Bait allowed Jan1 to March 31.
• 3 person crew conducting creel/spawning
surveys.
Preliminary Evaluation – Year 1
• Roving surveys and pressure counts used to
estimate catch-per-unit-effort, effort per angler
and total anglers.
• 113 anglers counted over the season,
– 194 hours of trips, 24 steelhead caught – 19
released, 5 harvested
• Estimated total catch = 356
• Retention rate of 20.8% = 74 steelhead
harvested – 59 wild.
Preliminary Evaluation – cont’d
• 17 spawning/redd surveys (~1 km ea.)
conducted on 7-14 day rotation.
• Randomly selected and spatially balanced.
• Surveyed January through April.
• Estimated 338 redds, 579 spawners (70
hatchery strays).
• Including C&R mortality & harvest = 579 wild
steelhead entered river.
• Harvest rate estimated @ 10.2%.
