Whilst on Arran for a week this August I was taken out by one of the locals to service his lobster pots, he uses mackerel as the bait so we had to catch some whilst out there. I caught 60 odd in just over 30 minutes
including several washing lines of one on every hook
. We then went close inshore between the rocky outcrops to get several pollack
I cannot say enough about how friendly everyone we met on Arran was.
