Trout \Trout\ (trout), n. [AS. truht, L. tructa, tructus; akin
   to Gr. trw`kths a sea fish with sharp teeth, fr. trw`gein to
   gnaw.]
   1. (Zool.) Any one of numerous species of fishes belonging to
      {Salmo}, {Salvelinus}, and allied genera of the family
      {Salmonidae}. They are highly esteemed as game fishes and
      for the quality of their flesh. All the species breed in
      fresh water, but after spawning many of them descend to
      the sea if they have an opportunity.
