Providing the pond is not too shallow the ice will only freeze on the surface. the fish then move to the lower depths of the pond where their metabolism slows down and they live in a semi- state of hibernation. Your fish should have built up fat reserves in the summer which will see them through this cold spell. Once the ice thaws and the water warms the fish will start eating again. Remember only feed your fish in the summer and stop once the cold weather arrives and you should have healthy fish that will live quite happily through the winter.
This answer is right as far as it goes, but the main problem can be a lack of oxygen available to the fish and other wildlife, especially if there is rotting plant etc debris (which can give off toxic gases) in the pond.
I would recommend researching this topic more thoroughly if you don't want to risk losing your fish!
PS This is Gipsygal speaking - I didn't provide the first answer, just added to it. Not sure how to make this clear! Oh well, I don't suppose it matters, no-one will read it anyway!
To answer this question, you have to account for many variables. Excluding morphology of the lake and generalizing behavior (as well as species of fish) it is possible for fish to die during a freeze. Still, there are many mechanisms that allow for fish to survive these common events. Most fish adjust behaviors, by vertically migrating to allow for the change in temperature or they may migrate from the lake. Other species produce anti-freeze proteins which alter the physiology of the fish.
If you need a more in-depth answer, just message me.
A pond typically freezes from the edges towards the center. This is because the edges are exposed to colder temperature conditions compared to the deeper central areas. As the ice forms along the edges, it gradually spreads towards the center of the pond.
Lime is applied in ponds to raise the pH level of the water and stabilize it. This helps to create a more suitable environment for aquatic life by reducing the acidity in the water. Additionally, lime can help to control algae and improve water clarity in the pond.

Rainfall can increase the water level of a pond, making it deeper. Heavy and prolonged rainfall can lead to runoff, which can fill up the pond quickly.
Organisms in a cold pond environment rely on the fact that ice (solid water) is less dense than liquid water, allowing it to float and insulate the liquid below. If solid water were denser than liquid water, ice would sink, potentially causing the entire pond to freeze from the bottom up. This would make it difficult for aquatic organisms to survive due to the lack of liquid water and the absence of a stable thermal layer.
A pond of water will freeze at or below 0 degrees Celsius (32 degrees Fahrenheit).
Ponds freeze when the air temperature drops below freezing, causing the water in the pond to also freeze. The ice that forms is less dense than liquid water, so it floats on top of the pond. This ice layer acts as an insulator, preventing further freezing of the water underneath.
A pond, being fresh water and smaller, would freeze first. Sea water, being salty and larger, also constantly affected by the tides and wind, will only freeze in very extreme coldness.
The ocean, in a pond only the top layer will freeze!
Pond De-icers help ponds that freeze often because of winter. If you do not remove the ice, the water could become harmful.
By turning to ice
A pond de-ice is a small heater for the winter months that makes sure the water does not freeze. You can purchase them online at www.pondmerchant.com or at a dyi store in your area.
In extreme freezing conditions, a shallow pond may freeze down to the bottom. If the pond is at least 18 inches deep, the surface may freeze down to a couple of inches.
if it is a cosmetic pond put your fish in an aquarium and drain your pump so it doesn't freeze and break drain your pond
Fish generally go down to the bottom of the pond where the water does not freeze and sort of hibernate for the winter. That is why it is important to make your pond so deep that the water will not freeze all the way to the bottom. (www.rosepond.com)
