The 2 photos of lakers are legit but from a long time ago. They came from Alouette. The one held by the guy in the orange floater coat was caught in 1998 in a gill net by BC Fisheries. Theoretically, there could be a behemoth or 2 cruising around in Alouette.
Sorry to hear a big bull trout was mishandled and released or killed ... there are not many in the lake. Having said that, retention of 1 char is allowable, for now, so there's nothing wrong with killing one. Sticking hands in the gills before releasing one is another story.
