Some of these are deceptively harmless seeming and there are one or two that may make you decide they can just have your fish. There are, however, a few things that can be done to help your little swimming friends.
The easiest, and many say the most effective, is to give your fish a hiding place. If predators can’t catch them, they can’t eat them. The answer is lots of floating plants and something to hide under. An easy and inexpensive solution is laying a piece of black PVC pipe on the bottom of your pond.
Decoys work well for some types of predators. A few (like this heron) are territorial and if they think an area is already dominated by one of their own, they will not intrude.
Risking an attack by a natural rival like a snake, owl or alligator is another thing many will avoid. Remember, decoys need to be moved around often, animals can be very smart.
Your watergarden can also be covered with a net to keep most predators away. It can be covered at night when most hunters are out. A lot of people also cover in the spring and fall, when predators are the most active.
If a bear decides your back yard is where he likes to eat dinner, then I suggest a nice saltwater aquarium : )
