How to Protect Your Pond Fish From Attack

If you’ve been spending more time at home like so many in our area of New York, we bet some of that’s been outdoors. And those with a pond are probably noticing that your pond fish are coming out of hibernation. Ahh. Spring.

One thing we hope you haven’t noticed, however, is any of your precious koi suddenly disappearing!

Now if that’s the case, we feel your pain. Not only do we enjoy watching and feeding these jeweled treasures, koi help balance the entire ecosystem of a pond. So we get it that you want to protect them. 

 

Safety Begins with Good Pond Design

Herons Don’t Like Deep Water

Herons Don’t Like Deep Water

If your koi pond was designed and built well, it was designed and built deep.

A water feature with sufficient water depth, for example, will dissuade raccoons and cats from going after your fish, since neither species enjoys swimming to get their dinner.

Plus deeper water at the edges (more than 18” deep) discourages the most challenging predator, the heron, from wading into your pond. Herons enjoy walking around in slightly shallow water.

Deep water really puts them off.

So a pond designed with high rock ledges and no easy wading entrance discourages a heron from hunting your fish.

Another helpful idea is adding a waterfall feature. The continuous movement of bubble rocks, waterfalls, or even water from nearby sprinklers, will put off many predators. Also, unlike still water which offers a glass-like surface, bubbling water from a waterfall etc. disturbs that serene surface, making it harder for predators to see the fish underneath. 

“In addition, when we construct a pond, we frequently include underwater koi castles,” says Deck and Patio’s Dave Stockwell. “When the koi sense danger, they can hid in there until the creature has given up.”

 

 

Other Tips for Protecting Koi

  1. Statues: Some swear by scarecrows like owl statues. Others recommend a decoy-heron. Indeed, being territorial, herons will usually avoid conflict with what they perceive as another heron. Be sure the decoy is large enough to appear as a reasonable threat, however. And it is also important to move the decoy every few days. Herons are clever and will soon figure out a decoy that never moves isn’t a danger.

Motion-Activated Sprinklers 2. Another effective deterrent is installing a motion-activated sprinkler. We found, for example, one gardening expert, the Laidback Gardener, who says that after testing just about every animal repellent conceivable: “…the only simple deterrent that keeps most animals away in the long run is the motion-activated sprinkler.”

The motion-activated sprinkler is just one of several deterrents that should be used, adds Dave. “It can be effective, but works best in combination with some of the other suggestions we’ve given here today.”

3. Pond Netting/Fish Wire: “The most effective guarantee for safeguarding pond fish is pond netting,” says Dave. “But, because they spoil the look of the pond, most people prefer to use netting only during fall foliage. However, another suggestion which you’ll see in the following video seems a better alternative. Fish wire can be strung around pond areas where predators can get close enough to grab your fish.

The pond is sufficiently deep, including around the edges. There are also plenty of high rock overhangs to discourage predators. A motion-activated sprinkler and a koi castle offer the final bits of security.

How To Keep Pond Fish Safe from Other Creatures

First, Pond Fish Are A Good Thing!

When a pond water feature is well-designed-and-built, koi will naturally help balance the entire pond ecosystem.

However, many pond owners fear that the fish will be harmed or will not survive.

And while it is true that koi can be tempting to cats, raccoons, and herons, etc., there are precautions that will mitigate their attempts to reach your pond fish.

 

 

 

 

 

Adding Rock Overhangs

Adding Rock Overhangs

 

Adding koi castles and tunnels at the bottom of the pond will give fish a safe place to hide from many predators.

Include rock overhangs around the outside of the pond. This will, first and foremost, make any pond appear more natural while discouraging cats and raccoons from reaching into the water after the fish.

 

 

 

 

Pond Water Depth is Key

Planning a water feature with sufficient water depth can also dissuade raccoons and cats further, since neither enjoy swimming to get their dinner.

Plus deeper water at the edges (more than 18” deep) discourages heron wading.

Another helpful idea is adding a waterfall feature. The continuous movement of its water, or even water from nearby sprinklers, will put off many avian predators.

Other precautions koi pond owners can take is installing scarecrows, such as owl statues. A net will also work, but most pond owners prefer to limit net use to fall foliage season.

However, one particularly effective deterrent Deck and Patio has found is installing a motion-activated sprinkler.

Indeed, one gardening expert, the Laidback Gardener, agrees. After testing just about every animal repellent conceivable, he wrote in his blog last year:

“…the only simple deterrent that keeps most animals away in the long run is the motion-activated sprinkler.”

“At Deck and Patio, we believe that if you build your pond well, and install a motion-activated sprinkler, there really is no reason not to add koi to your pond,” says Dave Stockwell.

“And when using a motion-activated sprinkler, you might find it will drive unwanted animals away from your garden as well.”

 

 

 

Koi is a healthy part of this pond’s natural ecosystem; they have lots of room to hide as well as swim. The pond is sufficiently deep, including around the edges. There are also plenty of rock overhangs to discourage predators. Add a motion-activated sprinkler for the final bit of security, and you and there’s no reason to fear for your koi.
