Most pond fish species are well adapted to winter weather and survive just fine under the ice. But there are exceptions. Florida Largemouth bass, a favorite with many pond owners, are less tolerant of cold water than the northern Largemouth bass. Under extremely cold conditions, under-ice mortality can occur.
Can fish live in frozen ponds?
If your pond only freezes over for a day or two, your fish should be fine, but if the entire pond surface is frozen for more than a few days (or even weeks), you’ll need to take measures to break the ice. That being said, even a small opening in the ice can be enough to allow CO2 and waste to escape.
How do you keep fish alive in a frozen pond?
A layer of ice across your pond can block the air/gas exchange that is so critical to supporting aquatic life. This is why you should cut a hole in the ice so that the water can receive the life-supporting oxygen the fish need to survive.
Does cold affect bass?
Remember, the air temperature doesn’t have any effect on bass. “As the water starts to cool again in the fall, forage fish such as shad move shallow, so the bass follow.
What fish can survive being frozen?
Every winter, the northern European crucian carp gets frozen into the ice, and receives no oxygen. Every spring, when the ice melts, a seeming miracle occurs: the fish emerges from the ice and resumes normal life.
How long can a fish stay alive frozen?
Any frozen fish or shellfish will be safe indefinitely; however, the flavor and texture will lessen after lengthy storage. For best quality, freeze (0 °F / -17.8 °C or less) cooked fish for up to 3 months. Frozen raw fish is best used within 3 to 8 months; shellfish, 3 to 12 months.
How do fish get oxygen in a frozen lake?
Different fish species do this either by absorbing oxygen into their skin, into the blood vessels in the walls of their swim bladders, stomach and gut, and some even inhale the air bubbles that form underneath the ice through their mouth.
Can fish live in ponds in winter?
As long as your pond does not freeze to the bottom and an air hole is provided on the pond’s surface, your fish will survive the winter. If your pond is at least two-feet deep, the proximity of the earth to the pond’s surface will keep the pond from freezing any deeper than eight inches.
Should I take the pump out of the pond in the winter?
If you have no aquatic life in your pond, it is safer to have the pump off when temperatures fall below freezing so you can avoid damage to the pump. You may even want to empty your pond of water as this can prevent damage from ice buildup.
Should I break the ice on my fish pond?
Remember: Never break the ice to create an opening, because you’ll risk causing harmful shockwaves that can injure or even kill your fish. Instead, use a de-icer. A de-icer can help your fish survive by allowing harmful gasses to escape through a small ice-free opening in your pond’s frozen surface.
Can bass live in frozen water?
Most pond fish species are well adapted to winter weather and survive just fine under the ice. But there are exceptions. Florida Largemouth bass, a favorite with many pond owners, are less tolerant of cold water than the northern Largemouth bass. Under extremely cold conditions, under-ice mortality can occur.
How deep do largemouth bass go in winter?
“You can catch largemouth bass from 5 feet down to 35 feet deep in the winter,” Rojas says. “I look for wood and leftover sparse patches of grass. With lack of vegetation and the cold water temps, largemouth tend to be grouped up in small areas. Any cover near deep water can be good.
Do bass go shallow in winter?
Big bass seek deeper water for its warmer temperature zone, yet the fish like to have a spot with a short route to the shallows. This spot allows bass to move up quickly into the shallows on warmer days to feed, but the fish can quickly drop into the comfort of the deep warmer water when wintry weather turns nasty.
Can fish freeze and still be alive?
Can fish and other aquatic creatures really survive in a state of suspended animation until spring? The surprising answer is yes, sometimes. It is true that some fish can spend the winter frozen in ice and come out swimming once the ice melts. Not all fish get caught in the ice, of course.
What fish can survive the winter in a pond?
Koi, Shubunkins and most goldfish survive winter by staying inactive at the bottom of the pond where the water remains a constant cold temperature.
What fish can survive winter in a backyard pond?
The Best Fish Breeds That Will Survive Winter in Outdoor Ponds

- Bluegills.
- Fathead Minnows.
- Golden Rainbow Trout.
- Goldfish.
- Koi.
- Pumpkinseeds.
- Redears.
How deep should a pond be to not freeze?
18 inches deep
As a rule of thumb, ponds need to be at least 18 inches deep, ideally 24 inches or more, to overwinter fish. If you have larger fish like koi or live in an area with severe winters, your pond may need to be even deeper (48 to 60 inches) to avoid freezing.
Do fish freeze in frozen water?
If rivers, lakes and ponds froze all the way through, fish would have a problem. However, when ice begins to form on freshwater bodies, it is less dense than the water and floats to the top. As long as there is some liquid water below the ice, fish will survive.
How do fish stay warm in cold water?
In short, the fish are still there, they are just much less active. Because ice is less dense than water, ice forms on the surface and provides some insulation to the waters below, keeping the fish warm enough to survive. Fish are cold-blooded.
Why does bottom of lake not freeze?
The gravitational weight of all the water higher up in the lake presses down on the water deep in the lake. The pressure allows the water near the bottom of the lake to get cold without expanding and rising. Because of the pressure, the water at the bottom of deep lakes can become cold without freezing to ice.
How fishes can survive in the extreme winter when ponds and lakes are frozen?
Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds.
