Herons are big, spectacular-looking birds that are interesting to watch. However, being fish-eaters, they can also wreak havoc on a fish pond. Herons tend to view fish ponds as handy pools full of easily caught treats. Unlike other water birds, herons usually walk up to a pond from nearby rather than alight on the water. They also prefer a pond where they can see both the fish and the surrounding area easily. Make use of these characteristics to keep them out of your pond.

  1. 1

    Create hiding places for fish with rocks or short lengths of PVC pipe.

  2. 2

    Measure the circumference of your pond and buy the same length of wire mesh (hardware cloth) plus a few centimetres. Form the wire mesh into the shape of your pond, allowing a little extra. Secure the ends together with wire and place over your pond. This forms a simple fence that prevents herons from alighting near your pond and wading in. Tent pegs are a fast way to secure the fence in place, if your pond is surrounded by soil.

  3. 3

    Surround your pond with shrubs or small trees. Herons prefer water bodies where they can spot predators from a distance. A pond enclosed by vegetation makes them feel insecure, and they are less likely to pay regular visits.

  4. 4

    Install a small pond fountain. This disturbs the surface of the water, making it difficult for a heron to see or catch the fish.
