I just bought a house in Upstate NY with a 100'x50' pond on the property. It has large golden fish in it (Not sure if they are Koi) as well as many smaller ones. Recently we have seen two alligator snapping turtles walking around the pond and are worried they are eating the fish. Is there a way to get rid of these things? I have two small children (Under four years old) and have safety concerns too. I have lots of other questions about maintaining the pond and fish, but need to read through the newbie section first I guess.
