It insulates the fish from the cold air above.
The fact that ice floats means that the lake probably will not freeze solid all the way down. There will still be liquid water at the bottom of the lake where the fish can stay alive all winter.

The ice that covers a lake actually insulates the deeper water preventing it from freezing too, this allows fish to continue to swim and feed during the winter.
big hesk sits on the ice and breaks it for them...... lol

The people fish in the summer by going to the lake.

As water freezes, it expands, becoming less dense. This means that the ice is on the TOP of the lake, and the fish are below the ice, in unfrozen water. If it were not for this property of water, lakes would freeze from the bottom up, killing the fish. Most things do NOT expand when they freeze.
Lake Vostok is the largest sub-glacial lake in Antarctica. It is 13,000 feet under the surface of Antarctic ice. It is about the size of Lake Ontario. Scientists believe the lake could have ancient organisms, bacteria, and even fish.
Fish go further down than the ice. The ice usually doesn't freeze all the way to the bottom. If the fish are trapped in shallow water or if the lake or stream freezes to the bottom, they will freeze.
Lake Erie is the lake with the highest fish population
