Once the locals figured out they could be eaten, the nutria's numbers began to decline. However, the damage to the levees was already done. Last time we were down there, the workers had their own version of a nutria "soft-taco" they shared with us. It was Ok, but I sure didn't ask for seconds. Great people down there. Sure wish I could find out something about the Avondale shipyard and those folks.
Louisiana's wildlife department has a program to encourage people to catch and eat nutria, the critters are so overpopulated.
