218 AMERICAN FISH CULTURE. 



ESOCID^. 



The various species of the pike family are not herbivo- 

 rous, insectivorous, or omnivorous, but simply piscivorous, 

 subsisting entirely on fish with, perhaps, the exception of 

 an occasional frog. If one wishes to exterminate the trout 

 of some pretty mountain lake or a pond let him introduce 

 any kind of pike. " Verbum sat."
