In some cases fish can survive freezing. Goldfish in small ponds are a great example, they can stay frozen all winter in the pond and still be alive in the spring. It depends on the type of fish and the condition that it was frozen in.
Well it would die definitely. It would be equivalent to freezing an animal and seeing if it is still alive when defreosted. If that existed, we could live forever. It would be like that spongebob episode where patrick and spongebob are frozen in a giant freezer and wake up in the future. When lakes freeze though, only the top freezes, so the fish can still live under the ice.
