Thanks Bill, we also have raccoons in our backyard quite regularly but rarely if ever see any sign that they are visiting the "sushi bar". We have a neighbour a few blocks away and a friend a few miles away that both have raccoon problems with their ponds, why we don't is pleasantly puzzling (knock on wood). I used to think the key was pond depth (most of ours is about 3 ft deep with about 1/5 of the pond at about 1 1/2 ft) but both our friends ponds are as deep or deeper than ours. The neighbour has a mesh screen which destroys the look of the pond and the other friend receives a couple dozen new fish from us each spring to restock their raccoon feeding station as we have to control the number of fish to avoid overloading our filters. Both the goldfish and koi spawn in our pond several times a year we even get crosses between koi and goldfish.
