If I understand correctly, a live fish is a "pez" whereas one coookedcooked or otherwise ready for eating (dead) is a "pescado."
So when exactly does this transformation take place - when the fish is caught, or when it dies? If a bear is standing in a river and catches a pez, does it become a pescado as soon as he's got it in his claws, or only after he kills it by biting it?
