It depends on how big your pond(s)is/are and how much you can afford to share. If you were in the business of raising fish like I am he would have to go. I don't know about your state but they are protected in my state. Maybe live trap and relocate or simply trap? If you don't know anything about trapping you may be able to get someone to do it for you. Be aware also trapping season may play a part in this and you may be able to get some kind of nusiance permit if it's out of season and you are allowed to trap.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
