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.

Not always: some lakes have a high salt content & cannot freeze.
Zero degrees Celsius.
yes
lime is applied in the pond so that the water to be clean and remove germs.
If the temperature is below freezing a water supply will freeze in the cold weather. The water will not freeze if the temperature is 32 degrees or more.
HOW LARGE IS THE CONCRETE POND?
Well this of a natural ice skating area, the edges are danger zones because they are the thinnest parts. The reason the safest skating is at the center of the ice on a body of water is because it is the thickest, this happens because the center is the first to freeze because of colder deep waters. The coldest water is at the deepest parts of the body of water, and when it cools it freezes and rises to the sufrace where it completes the freezing process at the top and in the center.
below 5 degrees
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.
It freezes first on the sides where the water is very shallow, thereby less able to circulate heat up from the bottom to keep from freezing.
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)
