Capelin \Cape"lin\, n. [Cf. F. capelan, caplan.] (Zool.)
   Either of two small marine fishes formerly classified in the
   family {Salmonid[ae]}, now within the smelt family
   {Osmeridae}: {Mallotus villosus}, very abundant on the coasts
   of Greenland, Iceland, Newfoundland, and Alaska; or {Mallotus
   catervarius}, found in the North Pacific. The Atlantic

   Note: This fish, which is like a smelt, is called by the
         Spaniards anchova, and by the Portuguese capelina.
         However the {anchovy} used as a food is a different
         fish. --Fisheries of U. S. (1884).
