What Do Fish Do All Winter? How Do They Survive?


Feeling a little uneasy about leaving your fish in your backyard pond or water garden this winter? It’s common to feel a little guilty about leaving your fish exposed to frigid temperatures and harsh weather conditions.

Believe it or not, your fish are actually designed for winter dormancy.

If your pond is at least 30 inches deep, your fish can survive the winter weather. What will your fish do all winter in your backyard pond? Not much. A fish slows its metabolism down during the winter months, going into a state of hibernation. This means, your fish won’t really be swimming around or even eating.

A fish can easily survive during winter months without food and without the warm weather. However, in order to survive, there needs to be at least one open area on the pond surface that is not covered by ice. Your fish will need this in order to continue “breathing” under water.

The best way to ensure your fish are safe in your water garden during winter is to invest in a quality pond heater. A heater can help keep the surface of your pond from freezing over completely.

Another option is an aerator,  which can serve a similar purpose to the pond pump, but is a more affordable option if your area doesn’t often get freezing temperatures during winter. You could also use backyard pond pumps to keep the water on the surface of your pond circulating to prevent freezing.

So, you can rest assured with proper pond winterization your fish will be safe and sound all winter long.
