PIKE PERCHES 
DESCRIPTION 
The pike perches (Stizostedion) include the largest members of 
the perch family inhabiting American waters. They may be dis- 
tinguished readily from other fresh-water fishes by the long, rather 
pike-like body, with two dorsal fins, the first consisting of spines 
and the second of soft, segmented rays. The presence of a spinous 
dorsal serves as a ready means of distinguishing the pike perches 
from the pikes (family Esocidee), which include the pickerel and 
muskellunge. The pikes have but a single dorsal fin of soft rays 
situated on the posterior part of the body. As the pike perches are 
members of the perch family, it is advisable to adopt this name and 
thus overcome much of the confusion of the species of the two fami- 
lies. Three species: are found in our waters—the yellow pike perch 
(Stizostedion vitreum), the blue pike perch (S. glawcwm), and the 
sauger or sand pike perch (S. canadense griseum). Of the three,
