I remember that one although I wasn't active on the forum at the time... I knew it was a trout because many years earlier when I was first on the forum I put up a photo of a salmon lower jaw in a similar state and everybody threw doubt on it because of the size of the teeth. Those of us who poke about on the rivers all winter are familiar with skulls like that. If I recall correctly Sandy (Fishtales) said the one above was a trout but everyone else no no it's an exotic tropical carnivor!
Anyway trouts have teeth!
