    If one was to use the terms strictly cladistically, then to my understanding, ducks would be considered a type of fish, being descended from them if one goes back far enough. The reverse of fish being a type of duck cannot be said. Therefore, I hold that in the case of a fish-duck, there is a stronger case for the creature being considered a fish, than it being considered a duck, and therefore, this is a fish.
