Blues show up in a variety of habitats. You find them both deep and shallow, along the Atlantic coast. And they also frequent bays and estuaries, often venturing into some really skinny water. But perhaps what they are most notable for is their blitzes, their ferocious attacks on schooling menhaden, sand eels, bay anchovies, or anything else that swims for that matter, including their own young. For fly anglers, however, stakling big bluefish in the shallows, where they tail like a bonefish, is hard to beat.
