Contents Notes |
A spawning and incubation channel constructed in 1959 on Abernathy Creek near Longview, Washington, has been used for seasons to incubate fall chinook salmon and chum salmon eggs. Survival of eggs from both species was higher than reported for other channels and controlled-flow projects. Studies included effects of sedimentation, egg planting density, and stage of egg development at planting on survival. In early experiments sediment in the upper sections substantially reduced survival. In later experiments, after the construction of a sand trap and settling chamber, survivals significantly increased. |
