Banded Pickerel 



Esox americanus Gmelin 



This small pickerel, reaching a length of about a foot, oc- 

 curs only east of the Alleghany Mountains, from Massachusetts 

 to Florida, the westernmost record being Flomaton, Alabama. 

 It is abundant in all lowland streams and swamps of this region. 

 It takes the baited hook readily but is too small to be of much food 

 or game value. 



Easily known by the complete scaling of cheeks and opercles and 

 in having 12 or 13 branchiostegals. 



Little Pickerel ; Grass Pike 



Esox vermiculatus Le Sueur 



The grass pike occurs abundantly throughout the middle and 

 upper Mississippi Valley and in streams tributary to Lakes Erie and
