Koi are capable of surviving through an entire winter in a frozen pond, provided their water has sufficient oxygen. Poor-quality water won’t last if they are frozen on top, as they won’t be able to surface in time to breathe.
In addition to their ability to survive in cold water, the Koi also have a number of other adaptations that allow them to thrive in the harsh environment of the ocean. Kois have an excellent sense of smell, and their eyesight is excellent. They are also very good swimmers and can swim for long periods of time without the aid of a buoyancy device.
This is a feat that few other animals can achieve.

Can koi survive freezing?
If the water doesn’t get too cold for the fish, it isn’t bad for them. If you have a pond that’s already frozen, and you want to move it to a warmer location, you’ll need to make sure that the water temperature is at least a little bit warmer than it was when you moved it in the first place.
You can do this by adding a small amount of water to the bottom of the tank, or you can add a few drops of aquarium salt.
If you add salt, be sure to add enough so that you don’t end up with too much salt in your water, but not so much that it makes your tank look like it has been sitting in salt water for a long, long time.
It’s also a good idea to check the temperature of your new pond regularly, just to be on the safe side.
Can fish survive being frozen in a pond?
If your pond only freezes over for a day or two, your fish should be fine, but if the entire pond is frozen for more than a few days, you’ll need to break the ice. Even a small opening in the ice can allow CO2 and other gasses to escape.
If you have a pond that’s frozen solid for several weeks or months, you may want to consider adding a layer of ice to the bottom of the pond. This will help keep the water from freezing over, and it will also help prevent the fish from getting frozen to death.
How long can a fish be frozen and live?
The flavor and texture of frozen fish and shellfish will diminish after lengthy storage. For the best quality, freeze cooked fish for up to 3 months. It’s best to use a frozen raw fish within 3 to 8 months.
Should I bring my koi inside for the winter?
Even though it is already winter, and we recommend not disturbing your fish while they are “hibernating”, it’s not too early to start planning for next winter. If you are planning to bring your fish inside next year, this is especially true.
How do fish survive after being frozen?
Water below freezing holds the most oxygen because it holds more dissolved gas. Because fish metabolism has slowed down, they are using less oxygen. Some fish go into a state called torpor that decreases their need for oxygen and allows them to stay alive longer.
What do fish do in a frozen pond?
Winter-kill events occur when a lake becomes oxygen deprived. As the anoxic zone creeps upwards into the water column, fish die from suffocation as they cling to the under- surface of the ice.
In the case of Lake Erie, the lake’s oxygen levels have been dropping steadily for the past several years, according to a report from the National Oceanic and Atmospheric Administration (NOAA). The lake is currently at its lowest oxygen level since records began in the early 1970s, NOAA said in a press release.
How fishes can survive in extreme winter in ponds and lakes are frozen?
Oxygen is trapped beneath the layer of ice. It is possible for fish and other aquatic animals to live comfortably in the cold water. The water temperature of the Arctic Ocean is about -20 degrees Celsius (-4 degrees Fahrenheit). The average temperature is around -10 degrees C (-18 degrees F).
