Hi Rob,
My understanding from reading the stuff on the website is that ADAA members can fish for coarse fish at Loirston within the coarse fishing rules. This would mean sticking strictly to the designated coarse areas, seasons and methods when targetting roach. My understanding is, and I may have got this wrong, but ADAA game anglers can still fish for trout within the designated coarse areas. The only conflict I can see is that ADAA members are allowed to worm for trout over the winter and early spring so not sure how you can say what you are targetting ? !!
ACAA are there by invitation and on a trial basis only - 6 months according to the website. Personally, I welcome them and wish them every sucess in their fishing at Loirston. Might be a good amusement over the close season winter months for bored trout fishers too, though sitting about on your erse for hours at a time in the cold is not exactly a favourite pastime of mine ?
