Davy and Sam...I have this problem daily in Aberdeen. Although neither the Dee or the Don support a big head of coarse fish (Dee, Pike, maybe Perch, Don, Pike gudgeon, possibly bleak) I still find the odd pike cut in half laying on the bank. I also got into trouble for returning a Salmon!!!! So I left all the clubs I was a memeber with.
I have a local Loch that has a KILL ALL PIKE policy, which, of course, I ignore, although a 35 pounder was killed 3 years ago by some local pratt!.
The Tay system is getting better, grayling and roach fishing in the winter is no problem really, and there are monster pike in there, but I can wobble deadbaits etc as this is an illegal method. Its funny having a Salmon smash into a Jitterbig on the surface though...hehe
As time marches on, perhaps game anglers will realise the damage they are doing to angling (killing everything) and to the countryside (shooting seals, trapping otters, herons etc) as this all goes on in NE Scotland!! I remember seeing a group of people surronding a dying seal in the estury of the Don. When I got there, it was apparent that it had been shot in the side with a rifle. It must have been one of the gillies further upstream. I was fumming and so were the walkers. I tried to explain why a Gillie would do this, but, like me, they were very upset.
Did u know that pike will eat alllll the trout and salmon in a river?? Thats why they have co-exhisted for tens of thousands of years!!!!...Bloody ill-informed plonkers.
(sorry, not all game anglers think this way)
