Only one place to start Scrapman, go to the Anglesy bait Company at Gallows Point just outside Beaumaris (West side on the Menai Bridge road) You'll see a lot of beached yaghts and buildings witha garage fronting the road. Malcom's shop is behind the pumps next to the Chandlry store. Go there after about 2 in the afternoon and he'll put you right.
It's always dangerous to tell any one to fish anywhere from a distance and I hav'nt been there for abot 3 weeks. I know the Menai Bridge area best and always fish the last two hours of the ebb (well I'm usually after peelers then to) and the fisrt two-three hours of the flood. I don't know if the Bass have penetrated into the Swellies (between the two bridges) but if they have then you may well need to use Crab. Otherwise be guided by Malc. who will put you on the best, or at least the most productive ones now, and suggest the best methods and bait! Good luck, i'm hoping my old back allows me to try next weekend so leave some for me!
