Plenty feed off the Island in the form of Sticklebacks, I was watching the trout slashing at these one day when I took my Granddaughter out to the castle, all round the shore the trout were feeding away on the shoals, so there must be plenty of feed to produce larger fish, pre the last war the estate here took stock from Howietoun and these were supposed to be Loch Leven strain, I would reckon that most of the handy lochs round here have that strain in them, a definite difference can be seen from the darker trout in the higher lochans, although some of the bucket biologists have been busy in the past, as there are one or two lochans with the lighter coloured fish, easgach 1
