Size of a river otter
My neighbor down the road has a koi pond and he told me that recently river otters went over to his pond and ate all of his fish.
I recently got my pond going and bought a bunch of fish including koi and now I am alarmed that they could be next. I have to get a fence around the pond but I am unfamiliar with river otters and don't know how high it should be. How tall can the tallest river otter get standing on its hind legs? Can they climb up and over a fence? I really will appreciate your help in this matter.
