Les, up here in N wales, most people I know who fish do fish for the pot, trout and salmon, but I've always got this one bloke bugging me to bring him back a carp to cook. Also any pictures I show anyone, they all say "did you eat it?" none-anglers and anglers alike. Obviously there are some coarse anglers up here and I dont want to call everyone, but this is the general response in a game fishing area.
They really do think I'm insane when I tell them I've put the fish on a padded mat, applied antiseptic (I actually do this with all species) and am happy with just a picture. There again I break the rules on their waters too, often releasing trout in non release waters, when i've taken what i want...
