Very nice. I'm glad to see that modern dam builders are helping migrating fish instead of just creating a water storage and electricity generating structure. I made a vid of the Chinook salmon using a fish ladder on a California river. Hope you'll watch it sometime. Thanks for an informative video!
Wow, that was really informative. I have never seen the S-pattern ladder, nor the fingerling transport. Thanks! Hopefully if aliens ever visit us, they'll see things like this and spare us our lives. :P hahaha ;)
Good question - fish ladders are used only at certain dams where biologists have determined there is a need (in a fish migration path) and where there is a reasonable chance they will be effective. Unfortunately, sometimes, even with very careful design, fish ladders can fail because they do not match closely enough the natural experience of the fish.
Which cake first the fingerling chute or the migration ladder? I get the sense that the fingerlings were more important to the engineers since they pose a risk to the turbines.
How do the fish ladders address the problem of predatory pressure? Isn't think just creating an even smaller chokepoint for predators to take advantage of?
Very good point. It is true fish ladders can cause hotspots for predation. This requires more study for both the types of predation that result, and how new fish ladder designs might mitigate the problem.

I only just learned about the existence of fish ladders. Very cool. thanks for the info.

That's the spirit. Taking one for the team. Thank you for being the blood offering.
@@waibryte
Haha. ;)
I know, right? Dang. I can't believe my comment is 9 years old. Thanks for bringing me back to it.
@@waibryte
You were looking through TH-cam doing research on a fish gun?
@@waibryte
Ah, well, even though I'm not a vegetarian anymore, damn, I don't find killing anything funny. To each their own. :P Haha
@@waibryte
You kind of lost me there. Don't know what you were looking into.
Very interesting, good job
An informative video!!
Are fish ladders commonplace for most dams or are they only being implemented in certain areas?

@@Science_Man Makes sense, thank you for the reply! :D

That's an excellent question. I'm not sure... I will have to do some research into that to find out.
I have a suggestion for it. Can we use tesla value rather than that steps because for migrating fish like eel it could be useful
Very nice vid! thx man
What if the fish jump backward
thank you very much ..
It's good that some humans helping those fishes to breed but they have to change their pattern of survival sound like punishment

The first Salmon is a Chinook salmon
Cool
Any clearer version of the image showing the fingerling transport system beneath the dam?
I think we need to educate the fish next
I just learned about this ladder on PBS kids
i don't think that's a sockeye
That's a Chinook not sockeye just fyi
Cool
