Dolly Varden and people
- Dolly Varden and Bull Trout are extremely difficult to tell apart, making geography the easiest way to distinguish the two. If found in the Liard drainage the fish is likely a Bull Trout, while those found in the Peel or Tatshenshini-Alsek drainages are likely Dolly Varden.
- Dolly Varden were named after a character in Charles Dicken’s novel "Barnaby Rudge," who was famous for wearing a brightly-coloured dress reminiscent of the fish’s colourful markings.
- Due to their predation on fish eggs and fry, they were once blamed for declining populations of commercially valuable fish like Sockeye Salmon. This resulted in culling and bounty programs, including one during the 1930s in which Alaskans were paid 2.5 cents for each Dolly Varden tail.
