No, fish require water to be able to breathe and move around freely. Freezing fish also completely destroys their tissue and internal organs. While some kinds of frogs can handle being frozen entirely, fish are a different story.
Fish may also be harmed if they're in a pond which is entirely covered by ice. This prevents oxygen from entering the pond from the air. Fish need oxygen to survive, and can quickly be suffocated if they have no access to oxygen.
