I'm not so sure the pair of fish were frozen at the moment of attack as described by the news media. I suspect the pike choked to death, then floated, then froze. That makes a whole lot more sense of how natural fishy things happen.
I think in the second link they come up with that same conclusion.
Pretty neat find at any rate.
I remember my mom talking when I was just a small kid about goldfish she kept in our concrete cattle trough. Some got really large so they got transferred to the pond (what is now my old refurbished pond). They kind of forgot about them till one winter when my dad was chopping a hole in the ice for the cattle to drink and dad found a big carp size goldfish frozen in the pond ice.
