Check out this clip featuring Jeremy Wade from River Monsters : Season 5. It was filmed in Iceland as he was searching for the Loch Ness Monster in the season finale. He catches a Cod, Haddock, Flounder and some other smaller fish. He was searching for a “Stone Biter” but had no luck catching one of them. He does show the jaw of one and it’s a nasty looking thing, it has teeth that remind me of a Pacu or Sheepshead.
