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. 

The Pondliner.com Countdown to Winter

When summer winds down and fall is in full swing, it’s time to start prepping your backyard pond or water garden for the cooler months ahead.

Don’t feel overwhelmed, the fall season gives you enough time to space out your winterization so you can still enjoy the time you have left with your pond.

Use our winter countdown to help guide your fall pond maintenance efforts:

•  Clean-up – In late summer and early fall, it’s important that you start to remove as much debris and material from your backyard pond as possible. To do this, use a skimmer or pond vacuum to remove leaves, twigs and other build-up. Use netting to prevent any further debris from accumulating.
• Repot your plants – In fall, it’s necessary to repot your pond plants to divide and store. Non-hardy plants need to be protected before winter dormancy. Try to repot your plans as soon as you can.
• Bring your fish in – Don’t wait until the snow starts falling to remove your fish from your backyard pond. Your fish can become stressed when exposed to temperature shifts greater than 4 or 5 degrees, so the sooner you relocate them the better.
• Trimming – Prune any overgrown or long-stemmed plants to help promote growth next season. Also, trimming your plants can help you remove any leaves that might end up falling to the bottom of your pond.
•  Feed your pond plants – Late summer and early fall is the best time to start providing your pond plants with the nutrients and supplements they will need as winter approaches.

While there is more you will need to do to completely prep your pond for the harsh winter ahead, it’s important to start slowly and make the adjustment for your plants and fish a smooth one.
