Sockeye

Does transport of Sockeye through the Whooshh fish transport system measurably affect their upstream migration?

the conclusion

No and Yes. There were no findings of significance affecting migration, homing, or survival. However, the sockeye that passed over the top of the dam  through the Whooshh system migrated faster to the next two dams, 91 and 124 river kilometers upstream, respectively. These findings were statistically significant compared to the comparator Sockeye group which completed the Priest Rapids passage via the ladder.
