They are about the west coast, but patchy distribution, last years hot spots are often dead, yet other places are heaving with them. Argyll. My dogs have been feeding on Mackerel for a while now, among other fish and stuff. I never buy mixer, but my dogs also get my food waste.Just heard that they are in around the west coast of Scotland ;-) After BS's comments I was thinkin about hittin Blyth for a fishy weekend...mackerel by day...ladies by night :-D
