Its a complete shambles in UK with fishing and hunting.
.
respectfully, i'd disagree strongly with that Eunan - there are hundreds of wild streams in cornwall, devon, wales, derbyshire, yorkshire, cumbria, cumberland, scotland and N Ireland where all you need is a 20 buck EA licence and at the most pay five bucks to fish if anything.
some of the best brown trout fishing in the world is the wharfe, eden, wye and dove.
many local EA's offer voucher systems where you pay thirty bucks and get online tokens to print out and put in honesty boxes at the river, you can fish for 10 days on 10 rivers :

also in the wilds of wales, N Ireland, scotland and Cumbria you can hike as far as you can - i've hiked 15 miles to wild ponds and brooks, camped overnight and not seen a single sole.
read any book by Jon Beer and you'll realise that once you get outside the home counties there's a lifetime of cheap or free fishing for trout, salmon, sea trout and grayling.
no ticket required :
i found a link for the OP, which has a lot of information :

including Atlantic Salmon fishing for 30 bucks a day on the Bush river - of the Bushmills Irish Whiskey fame
best of luck
