Herrings are small oily fish of the genus Clupea found in the shallow, temperate waters of the North Atlantic, the Baltic Sea, the North Pacific, and the Mediterranean. There are 15 species of herring, the most abundant of which is the Atlantic herring (Clupea harengus). Herrings move in vast schools, coming in spring to the shores of Europe and America, where they are caught, salted and smoked in great quantities. Canned "sardines" (or pilchards) seen in supermarkets may actually be sprats or round herrings.
