It insulates the fish from the cold air.

Explanation:

As ice forms, it floats on top the water as it is less dense than water. This protects the fish from the freezing air, as ice is a great instulator. A good analogy would be why you stay warm in an igloo. The ice is a poor conductor of heat so heat cannot escape.
