I Pike fished Scaling a few times during October last year, only managed a small jack Pike (mind you the weather was awful). I have no idea how they got in there but they have been in for quite a long time and do go to a decent size. Unfortunately Scaling lost several 20lbers during 2006, apparently spawn-bound which is a shame
Hopefully if any of the trout fisherman catch one they would put it back unharmed but there are some narrow minded people about that think Pike spend all day eating through the entire trout population when really it's the total opposite.
I'll be back at Scaling this year to have another go at them, hopefully I find some of the bigger fish

Are you thinking of Pike fishing it Bucko or just curious?
