A neighbour of ours was sick of the local cat population eating the fish out of his pond so he put a wire mesh covering into it just a few inches down from the water’s surface.The sides of the pond were concrete with logs of wood all around but concreted in at the bottom to keep them stable. He got the mesh wire , cut a little bigger than the pond and turned up the edges and nailed the edges to the wood enough of a distance from the surface so’s it would be hard to see. He had no trouble with the local cats or birds after that, although it was funny watching them trying in vain to get at the fish.
