Koi fish predators are everywhere when it comes to koi ponds but how do you keep and protect your koi fish from predators. First off some koi predators are raccoons, snakes, frogs, cats, kingfishers and the worst predator of all the blue heron. All of these predators pose some risk to your koi but what can a pond owner do to protect koi from being eaten.
The first thing to protecting your koi from predators is getting to know the predator themselves. One thing that a racoon is afraid of is deep water as they usually fish in rivers from a log or in shallow water. What a koi owner can do is when planning your pond at the beginning is to make sure you leave steep edges that will help stop or prevent racoons from fishing for your koi and help keep your koi fish safe from predators.

The good thing is that there are certain things koi pond owners can do to help protect their koi fish from predators.
