Some parts of the southern US have a bounty on nutria tails. On top of the bounty I think there's some nice incentives because IMO invasive species are a relatively ethical source of fur (if you're killing them anyways, might as well use the fur). However I think these sorts of programs are tricky because if you make the incentives TOO good you can end up with really bad side effects. For example the (apocryphal?) story about how India created a cobra bounty to reduce the wild population, and people eventually realized it was easier and still profitable to just breed cobras at home. When the government realized this, they stopped the program. With no more incentive to raise the cobras, the breeders let them go, increasing the overall population.
