Not near as much as when I was a young man. The things I see the weirs helped out are crabs and Flounder. They killed the shrimp population back there. If you think there are a lot of shrimp in there, you should have seen it before the weirs and the first couple years after. I can hook you up with a couple fellers who used to shrimp the private marshes. They will tell you what it did.
And after Rita, when the levees were blasted open, there were suddenly a buttload of shrimp back there again. Fix the levees and the shrimp fall off again.
Everything eats shrimp. More shrimp, more healthy fisheries.
There should be a better way to fix the marshes than to block them off.
Flounder and Reds are always pretty good back up in there.
