They are basically collecting every fish they can get their hands on. (The Corps) is using technological mechanisms to corral juvenile fish into pipes that eventually dump them into barges or trucks.

Juvenile salmon have a biological clock that begins ticking as soon as they begin their trip to the ocean. They need to undergo changes that will allow them to adapt from fresh water creatures to salt water creatures and arrive at the ocean at the same time their bodies have completed the transformation.

The only time the dams are efficient at producing energy is during the spring runoff months. We can't simply flip a switch and release water that isn't there.

That means spilling water over the dams from spring until fall, 24 hours a day, as opposed to using turbines.

Many of them get back to normalcy by using their natural coping mechanisms. But by the end of the year, we still have 40-45 percent suffering because they are using negative coping mechanisms.

The fundamental mechanisms are probably going to be the same in all vertebrates, as even frogs and fish have gaze control. The promise here is that because we are doing this in owls, we can get at the mechanisms of how this works.
