Interesting questions guys. When I first opened Haddo years ago we caught Broons in good numbers, then they slowly "disappeared" and were not caught very often. A couple of years later I stocked some brownies and we started to catch the originals again almost straight away
( easy to tell by their different colouring ) I don't know why this was, but I suspect it has something to do with competing for a specific food item in the loch?
Over the past couple of weeks, since stocking some brownies in the loch ....... I am seeing the same thing happen again, we are catching some of the resident brownies that have not been making an appearance for a while
Also interesting to note that these fish appear to be feeding more at around midday at the moment
Best wishes
