When does pond water freeze?

Answer 1

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!

Answer 2

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.

Answer 3

Pond water freezes at 32 degrees Fahrenheit (0 degrees Celsius) when the temperature drops below this point. The freezing time can vary depending on factors like water depth, surrounding air temperature, and movement of the water.

Answer 4

Not always: some lakes have a high salt content & cannot freeze.

Answer 5

Zero degrees Celsius.
