Have a pond that I have worked on the last 10 years my wife has had it for 24. Today a large heron came and ate all the fish approximately 50 mostly goldfish some 8 years old and a couple as big as 3”. I’m asking for help in terms of what’s best to use to keep predators like that away(I’ve read he will be back). Due to it being on a high traffic street netting won’t work as it will become unsightly as I already have to remove debris daily. Please help?
