The 'red spot' thing is bollocks, utter bollocks.
My best from last season, 3 pound wild BROWN TROUT, not a red spot is sight:
So it's a Sea Trout ?
As a boy that grew up in Fife, I am familiar with the Loch Leven strain of trout. No red spots. In fact, Howietown, who supplied the stockies to ADAA ( who then stuck them in the Don) were famous for breeding this strain. Not sure if they still do.
I am totally dismayed by this. Ruined my day.
