Sorry its a late reply to this, but I went to Peterhead breakwater last Sunday and had 31 fantastic Mackerel (in the freezer now). All on Mackerel feathers, (in an hour and a half) the fish were in massive shoals right up against the wall, a sight to be seen! Never seen so many, great sport all on a light weight spinning rod with a two ounce weight on the end. My arms were knackered at the end!
Have just tied some flies to try at Bodam next week, I have been told you can fly fish for them at Fraserburgh, but I dont know the area well enough to tell you where.
