All my koi, shubunkin and goldfish are gone, eaten by raccoons this year. I have used wire mesh. But the racoons stand on it and wait patiently until the little fish swim up between the wires and then he nabs them! Once I caught a momma and family of 3 babies practicing their fishing techniques in my ponds! I chased them up in the tree. It was hard not to think they were cute. Then I trapped 3 racoons in our attic! They were cute too but one had my koi in his belly from the night before!! They are a menace here. I have used a motion detector Rain Bird with limited success. If only they would cover all areas of my ponds. But it doesn't. sigh. There is only one goldfish left now.
