In Lousiana there are these big rodents, sort of like coypu but smaller, called nutria. They are not native and are a serious pest and a threat to the wetlands. They are essentially big rats. Now some bright spark had the idea that a way of getting rid of them might be to eat them. Now, Cajuns are famous for being omnivorous so it was worth a shot. My sister lives in New Orleans which is why, about 30 years ago I ended up trying nutria gumbo. It was gumbo, but the meat was distinctly un-succulent and ratty. Rat Gumbo. You can see why the attempt to turn the nutria problem into a culinary solution failed.
It wasn't at all disgusting, as it was gumbo. But it would have been far better without the nutria in it.
I think the've also tried promoting the nutria fur industry, and have Nutria Rodeos and similar events where basically people go out in boats and shoot them and there are prizes for most killed, biggest one killed, dead nutria throwing contests and the like. The state will also pay a bounty for every nutria tail you hand in. Obviously they don't pay enough because the problem doesn't seem to be going away.
