These have to be manned? Like 24/7 or...how much human labor is involved here? What % of salmon make it into human hands and through these tubes?
Earlier attempts at fish ladders saw rates as low as like 3% for certain species of fish, per ladder/dam. Even if 50% of salmon got up them, if they have to pass 5 of them on the way to the spawning ground that meant 97% of salmon wouldn't make to the spawning grounds.
