You have lost me a bit there but the reason I ask, is that recently I was walking the dog around Burrator reservoir. As you do, I was trying to spot fish. Anyway right against the dam wall in the corner where the wind was blowing into it was a bloody huge great big fish swimming about. Probably picking of food items from the scum line etc. Like I said it was huge, but as the dam is very high from the waters surface I couldn’t tell what species it was. One things for sure Ill be taking a few floating pellets with me next time lol.

Yeah these are stocked, they are not natural, but they are very few and far between and the reservoir is so big they are almost like wild trout. The fish I spotted was probably some old dog that had managed to evade capture for donkeys.
