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 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

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.

Are Koi Carp Difficult to Keep in Backyard Ponds?

 

Koi are delightful ornamental versions of the more common fish known as “carp.” Koi were bred for color by the Japanese for their private ponds or water gardens. But, as some of you may already know, these lovely creatures aren’t just for show. Their presence can help balance the entire pond’s ecosystem and even help to reduce pond maintenance.

Why, then, are so many pond owners anxious about keeping them in their ponds?

“People fear they won’t survive. It is true that koi can be tempting to cats, raccoons, herons, etc., but there is much that can be done to reduce such threats,” says Bill Renter from Deck and Patio.

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

Additionally, including rock overhangs around the outside of the pond, which first and foremost will make any pond appear more natural, help discourage cats and raccoons from reaching into the water after the fish.

“Planning a water feature with sufficient water depth can also dissuade raccoons and cats further, since neither enjoy swimming to get their dinner,” says Renter. “Plus deeper water at the edges — more than 18” deep — discourages heron wading.”

Another helpful idea is adding a waterfall feature. Continuous flowing water into the pond isn’t just beautiful and pleasant sounding, but the ongoing movement from the falls will put off many avian predators and even stop mosquitos from breeding.

Other precautions koi pond owners can take is adding scarecrows, such as owl statues. But with ongoing climate change and continued new construction, changes to their habitat are also causing changes in the behavior of local wildlife. “If all else fails, a netting can be installed over the pond,” says Renter.

Tips for Keeping Koi Safe:

— make your pond as large and deep as possible

— try to locate your pond in an area that you can see from inside your home so you can chase away any predator that isn’t deterred by other means

—  try to include a waterfall to aerate the pond and scare away some predators

— lighting with movement sensors near the pond can frighten away an animal at night

— scarecrows (like owls) discourage many predators — herons and kingfishers in particular; some scarecrows also have moving sprinklers which do double duty to dissuade prey

—  don’t put food for the birds you’re trying to attract near the pond — put it as  far away as possible

—  create hiding places for the koi inside the pond such as castles and tunnels

—  if you still have problems, a pond net will do the trick.

 

Here’s a small sampling of our favorite Deck and Patio pond features. And, yes, even if not picked up in the photos, there are koi in each and every one.

 

 

Pond Koi:

Pond Koi:

Contrary to popular belief, pond fish will actually reduce pond maintenance, as they graze on string algae and bottom feed from the pond floor. (Note: Plants in this pond include bullrush, pink canna lilies, horsetail, and a “rose arey” hybrid water lily.)

 

 

Pond Netting:

Pond Netting:

It’s wise to have pond netting even if you don’t need it to keep away predators. In order not to let a collection of debris into your clean pond water, you’ll want to put a net in place before leaves begin falling in autumn. Then, simply pull it out when they’ve all dropped. You can tent the net so it doesn’t sag into the pond when it gets weighted with leaves, say experts at Aquascape Inc. (Photo/Pond Net: Aquascape Inc)

Are You Afraid to Keep Koi in Your Pond?

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.

Deck and Patio’s Outdoor Living Expert, Bill Renter, offers encouragement: “While it’s true that koi can be tempting to cats, raccoons, and herons, etc., there are precautions one can take that will mitigate these threats.”

For example, adding koi castles and tunnels at the bottom of the pond will give fish a safe place to hide from many predators. Also, including rock overhangs around the outside of the pond, which first and foremost will make any pond appear more natural, also discourages cats and raccoons from reaching into the water after the fish.

Other precautions koi pond owners can take is including scarecrows, such as owl statues. In the end, if all else fails, a netting can always be installed over the pond.

Here’s some of The Deck and Patio’s favorite award-winning pond features. And, yes, even if not picked up in the pictures, there’s koi in each and every one.

Reflecting Pond:

Reflecting Pond:

The homeowner wanted to accentuate the beautiful 1880 stone bridge structure with a reflecting pond. To allow the entire stone gazebo to reflect in the water, the pond had to be more than 250 feet long and 45 feet wide. This created the perfect habitat for koi. Lots of flowing water, rock overhangs, and lots of space to hide.

 

 

 

Natural Ponds:

Natural Ponds:

When creating a new pond, we consider each rock’s form, texture, shape and height. In addition, incorporating such finishing touches as plant material and gravel helps it appear as if it was created naturally.

 

 

 

Where to Position Ponds:

Where to Position Ponds:

We always look over the property for any new pond — both from inside and outdoors — in order to place the pond in the perfect location. Since in the northeast, we spend more time indoors that in our yards, it is essential to see, and perhaps hear, any water feature from key indoor locations.

 

 

 

Pond Water Movement:

Pond Water Movement:

Having the force of moving water into your pond is not only an aesthetic choice, but will deter many natural koi predators. Also —even if it comes from nearby sprinklers — pond water movement helps keep the pond ecosystem healthy by eliminating stagnation.
