Pond Fence: Protection against otters and herons for your pond

A pond fence keeps otters and herons away from your fish while leaving the animals unharmed. Complete sets with netting or polywire go up fast.

Pond Fence: So your fish stay put

A pond emptied overnight is a familiar frustration for many pond owners and fish farmers. Otters and herons are skilled hunters that can clear a pond in no time. Both species are protected, so you need a deterrent that keeps them away without injuring them. An electric pond fence is a proven way to do just that, both around a garden pond and around larger fish ponds, and it leaves the water itself open and easy to enjoy.

Against otters: low and electric

Otters usually come over the bank and try to slip under a fence or climb over it. A low, electrified net 50 cm high or several strands of polywire close to the ground will reliably keep them out. The Agrarzone otter fence set with 50 m netting comes with 12 V solar, and for larger sites the otter sets with 250 m of polywire are available with either 230 V or solar. It is important that the fence seals tightly at ground level and leaves no gaps anywhere along the bank.

Against herons: taller and all round

A heron does not land straight in the water but on the bank, and then wades in. A net all round the pond stops exactly that. The heron pond fence sets with 106 cm high netting and 200 m length are available with 230 V or 12 V solar. If you want to keep both predators out, the combined set against herons and otters with 50 m of netting is a practical solution for smaller ponds. That way you protect your fish stock all round.

Frequently asked questions

How can I tell whether an otter has visited my pond?
Typical signs are half eaten fish on the bank, webbed footprints in the mud and droppings with fish scales on stones. A trail camera will give you certainty quickly.

Is a net over the pond enough to stop herons?
A net over the water helps, but is impractical on larger ponds. A fence around the bank stops the heron wading in and leaves the pond open.

Is an electric fence by the pond safe for children?
The short pulses are unpleasant but harmless. Still, put up warning signs and explain to children that they should not touch the fence.

Keep otters and herons away gently

If your pond is suddenly empty, otters or herons are often to blame. Both are protected, which makes an electric pond fence the right choice: it keeps them away without harming them. Against otters, a low 50 cm net or polywire close to the ground works well, running tight along the bank with no gaps. Herons are stopped by a taller net around the pond, so they cannot wade in from the bank. For smaller ponds there is a combined set against both. Depending on the set, you can run the fence on 12 V solar or 230 V, so it also works at remote fish ponds with no socket. Run it close to the ground, check the voltage regularly and put up warning signs if children or walkers come nearby. That way your fish stay safe all year and you can enjoy your pond without worry.
