A pike is northern species of fish also known as a "pickerel" which can grow to be incredibly large. In the short story The Edge of the World, the villagers of Upper Posada tell Geralt and Dandelion all about the local monsters plaguing them; marauding pike included.
"...and a dangerous pike which tears linen from women's hands as they wash it — and just you wait and it'll be at the women themselves."
- pg.165, The Last Wish (UK edition)

The Witcher 3: Wild Hunt Edit

  • During the secondary quest A Dangerous Game, Zoltan and Caesar Bilzen start discussing the flavor of pike, with them having differing opinions on it. Geralt can give his opinion on it or not.
