Wikipedia Abstract

The blueback shad or blueback herring (Alosa aestivalis) is a species of ray-finned fish in the genus Alosa. These fish are silvery in color, have a series of scutes (modified, spiny and keeled scales) along their bellies, and are characterized by deep bluish-green backs. The most distinguishing characteristic of this species is the black to dusky in color of its peritoneum (the lining of the abdominal cavity).
