Abstract

Passage times of fish at velocities of 1 and 2 feet per second were compared in a 4-foot wide transportation channel, with a water depth of 6 feet. The timing zone was about 100 feet long. Passage times did not differ significantly between water velocities for any one of three species: chinook salmon (Oncorhynchus tshawytscha), steelhead trout (Salmo gairdneri), and sockeye salmon (Oncorhynchus nerka). The two salmon species moved faster than steelhead trout at both water velocities.
