Anyone who does that kind of damage (20 dead fish)- I saw them myself- is no angler.
Much of the litter, and sh1t, left behind is not by anglers either. They may have a rod or two set up, but they ain't fishing.
Mostly they are drinking, the rod is the excuse and passers-by think that they are about legitimate business, with permission, and pass by.
The police attitude (I am told) is that if you grant permission to fish, the mess left behind is yours to clean up- your problem.
The owners just don't want the hassle, lock the gates, dig up the paths, throw down some rocks to obstruct access- it has all happened.
The solution is simple- get permission, leave your name and address, agree to abide by the local rules (catch and release- whatever) and leave the place (and the fish) as you found it. If you don't - beware.
I cannot change the prices, but if it takes £X for myself and a couple of mates to spend a good day, on a good loch, free of hassle, not stepping in human sh1t, catching (OK, rarely!)and returning decent fish I am well happy.
Whatever I think of Basil, the cost of him, and his staff, having to spend a morning shovelling human waste off the shore is only going to be passed on to the likes of us.
