Predators to Keep an Eye Out for if You Have a Koi Pond

Depending on its location and how it’s set up, a koi pond can be very similar to a natural body of water. Think about a garden pond where the backyard isn’t fenced and faces toward a greenbelt section or a lake. In this case, it wouldn’t be unusual for other species to become attracted to what they may consider a source of food and water. Beyond insects, frogs, snails, and turtles, backyard koi ponds also have the potential of attracting predatory species. What this means for koi pond keepers is that they should become aware of predatory risks, and they should also learn to minimize them. The friendly and knowledgeable staff at Aquatic Warehouse, a leading provider of koi pond supplies, lists a few common pond predators to watch for.

Domestic Koi Pond Predators

When we think about domesticated animals that may pose a problem to koi ponds, we automatically think of cats, but even dogs can sometimes be added to that list. Unless canines are trained to specifically stay away from ponds, their hunting and predatory instincts may take over when they see a lively aquatic ecosystem in a backyard with pond species moving around.

Wildlife Pond Predators

Wading birds are perhaps the greatest threat to koi ponds, particularly voracious species such as the Great Blue Heron, which can be found across Southern California along with a handful of other omnivorous heron varieties. Raccoons are also problematic, but the Great Blue Heron is definitely the alpha predator of the koi pond world because of its formidable hunting behavior. A great remedy for herons and raccoons is building your pond to a depth of 36” or more without steps that make it easy for critters to wade in.

Human Pond Predators

Unfortunately, koi theft is sometimes a reality for pond keepers, particularly breeders and aquarists who take pride in managing elaborate ponds. In 2019, NBC 4 in Los Angeles reported on multiple cases of pond theft that took place in upscale neighborhoods around Westminster, and many of the incidents were caught on home surveillance cameras. The perpetrator was apparently a man armed with a net, buckets, and wire-cutting tools. He even broke into a commercial establishment where exotic Japanese koi were kept and absconded with quite a few fish. Seasoned pond keepers will tell you that koi can be sold on e-commerce websites such as eBay and even Craigslist.

Keeping Koi Predators Away from Ponds

Getting back to dogs: if you’ve raised yours since they were young, and if they know they should stay away from koi, they could become great allies in terms of keeping predators away from ponds. In the case of felines, this is easier said than done because of their foremost instinct of going for everything that moves, but canines can definitely be trained as guardians. Fences and enclosures can go a long way toward keeping pond predators in check, but another option would be to invest in a motion-activated sprinkler system with powerful water jets.

In addition to keeping the fish in your pond safe from predators, you also need to keep them healthy by maintaining the aquatic environment properly.
