Objective 3. Reduce the risk that large hatchery programs pose for natural populations by developing ways of decreasing interactions between wild and hatchery chinook in streams and by determining need for more wild fish in hatchery broodstocks.
Evaluate fishery contribution and straying from net-pen releases below the falls.
Determine if hatchery fish released in the fall over-winter, potentially competing with wild spring chinook.
Explore options for trapping hatchery spring chinook above or near traditional fisheries but below wild spawning areas.
Determine need and look at ways of incorporating wild fish into hatchery broodstock.
Look at overlap of spawning between fall and spring chinook.
