The heron stop is a fence with bells to protect the pond fish against heron. Access to the fish is blocked and new attempts to approach the pond are prevented. An approaching heron lands near the pond and steps towards the water. When the heron comes into contact with an invisible wire and hears un unknown ringing, it will flee immediately. The fish will remain unharmed.
