The modern pike is very capable of snatching ducklings and even water voles. But it is nothing to the pikes of yesteryear, which would happily take on bears and paddling boar and rowing boats packed with marauders. They named the long pointy stick after the fish it was made to kill; as it leapt, the strongest warrior would hoist the staff and skewer the pike, and the whole army would feast on fish-flesh for days.
There was a man, once, who lassoed the pike. Bjorn, he was. Because he bred them small, for tastiness, the great pike are no more.
