What property of water allows fish in a lake to survive winters freezing temperatures?
I think you are probably talking about the fact that frozen water (ice) is less dense than liquid water, so freezing temperatures will enable the ice to form on top of the waterbody, but still allowing liquid water underneath so fish can survive. Also, ice is usually translucent, so it can still penetrate the ice, allowing algae to continue to photosynthesize, providing oxygen for the fish below.

Thanks for the feedback!
Water is at its densest at about 4 degrees Celsius, so ice floats. The ice stops evaporation and insulates the water below. The lake could freeze solid all the way down, but m…ost lakes do not.
Water expands as it freezes so becomes less dense than liquid water. Ice floats to the surface leaving liquid water (for fish to swim in) below the surface ice.
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 fis…h 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.
It's the fact that water expands as it freezes so ice that forms on the surface stays on the surface because it's less dense than the liquid water, if it got denser when it fr…oze the ice would sink to the bottom and thus the fish would die. So because it expands the ice stays on top, and water stays at the bottom where the fish can stay alive.
Expand when it freezes, creating a floating and insulating layer of ice.
Lakes never freeze to the bottom, so fish just live in the water below the ice.
There are many ways a fish can survive in freezing water. The simplest answer is like frogs and bears, they simply go into hybernation. They slow their heart rate and some eve…n stop there heart. There are even fish that live in water without Oxygen, look it up its quite interesting.

Many fish not only survive, but thrive, in freezing temperatures. Fish have a body temperature almost identical to that of the water, so no energy is wasted in heat loss. Fish… in the Arctic environment, where water temperatures stay close to a constant 28 degrees F (-2 C), have developed a protein that is a natural antifreeze in the blood. The protein keeps the blood free of ice crystals right down to the freezing point of salt water, so that the fish can live, breed, and thrive in amazingly cold water.
the whole water doesn't freeze (if it's not one of the poles) and fish can survive under that ice in the water because they are immune to really low temperatures.
What are the special properties of water that enables fish to survive in lakes that freeze in the winter?
A2. The whole of the lake volume does not freeze in winter. Due to the fact that ice expands when it freezes, and consequently floats. My old science teacher pointed out that …this is a GOOD THING, so the fish don't get stuck! A1. Fish benefit from many properties of water; just to name a few, water's capability as an oxygen carrier enables the proper functioning of fish's respiratory and metabolic processes, and its properties as a solvent allows the precise concoction of solutes and molecules that dictates the balance of the entire ecosystem. The unique property of water that specifically enables aquatic life forms to survive drastic temperature changes, however, however, is the same property that is largely responsible for providing the suitable conditions allowing the formation of life on Earth: The high specific heat capacity of water. Specific heat capacity is a measurable physical quantity that represents the amount of heat per unit mass required to change the temperature of a substance by a degree. Therefore, the high specific heat capacity of water sets forth a large thermal energy requirement for each degree of change in temperature. Consequently, a large shift in above-surface temperature (e.g., 30 degrees Celsius) translates to a much smaller shift in the water temperature (e.g., 10 degrees Celsius). In other words, a large body of water can be thought of as a thermally stable system resistant to temperature shifts. This very special property of water is a result of the extensive hydrogen bonding between the individual water molecules. This network of intermolecular interactions that enables water to absorb a large amount of energy before undergoing change is also responsible for other unique thermodynamic properties of water such as its high boiling point.

Solid water, ice, is the least dense state of water, which means that ice floats on top of the liquid water and insulates the liquid water so that it doesn't freeze. So the wa…ter beneath the ice remains liquid, and fish and other aquatic organisms can still survive in freezing temperatures.
what property of water allows fish in a lake to survive winter's freezing temperatures
When water freezes, it generally only freezes the top few inches. This actually creates a type of insulation, much like an igloo.
