That's incredible.
It's incredible to think of it that way, right?
And what they're doing when they're filtering, they're feeding on phytoplankton and then all the other little microorganisms that would then eat phytoplankton don't have anything to eat.
So you're basically cutting out the bottom of the food web, right?
Or the bottom of the food chain and stuff just can't move forward from there, right?
So-
So the whitefish have two issues with that.
One is if they're spawning grounds or these reefs where they like to spawn, if they're covered in mussels, they can't spawn there.
It just doesn't work.
And two, because this water is filtered and somewhat clarified, it's brighter, right?
And so the more sun gets down in there and literally the young fish, when they're just little minnows on the beaches,
They're literally getting sunburns that kill them because they should have a more turbid water.
The Great Lakes, even now, I don't know if you've noticed it when the last time you went to Lake Michigan, but last time I was there a few years ago, it's a very stark difference in the clarity compared to when we were kids.
Some fish are.
I think it's a little short-sighted to look at it that way.
I mean, they're winning right now.
It seems like it's not something that's sustainable.
Um, that was a word that was thrown a lot around with the people that I talked to that just like we, they, we had to start thinking about sustainability if we have, if we want to keep this thing going.
Yes.
As one fisheries biologist I talked to, he said, we're trying to basically manage an ocean.
