Benzene is a colorless, flammable liquid with a sweet odor. It evaporates quickly when exposed to air. Benzene is formed from natural processes, such as volcanoes and forest fires, but most exposure to benzene results from human activities. Benzene is among the 20 most widely used chemicals in the United States.
Lafrenz also attributes the taste of farmed branzino to the fish meal fed they are fed. Branzino, like salmon, is a carnivorous fish. In large aquaculture operations, small fish are caught and made into feed.
Branzino actually seems to be a little more delicate to the touch when cut through with a fork, and is usually served with the skin on. Also, Branzino I think tends to be a little thicker than Dover Sole. The Dover Sole I have had tends to be a much flatter fish and maybe even a tad lighter in flavor. Beyond that I don't think there is much of a difference. Please correct me if I am wrong.
