In this picture we see the use a network similar to those used for breeding hens and chickens, is a network of one-inch mesh which surrounds the pond, this prevents the ingress of flying and crawling predators such as birds, flying mammals (bats), marine mammals (otters) and other land animals like bush dogs etc. This network is tied with steel wires. Normally this system of protection is effective for a period of six to eight months depending on the environmental conditions of the area.
