HI Alfie, Here's a few stretches of water to try, TERN, RODEN, TEME, CLUN, ONNY, CERIOG AND THE DEE
I hope these help you out, The pic is the type of trap my mate uses, He baits them with rabbit guts in a small net bag
hanging inside, leaves them out for 3 days then checks them and rebaits them
( but he said there everywere so just try some local waters if none of the above are )
Goodluck and post your catches with pics look forward to them
