The Little Pickerel, or ‘‘ Grass Pike,’’ as it is sometimes 
called, is common throughout the state in suitable localities. Its 
favorite haunt is the weedy pond or backwater or overflow pool 
of some stream, and in such places it is sometimes very abund- 
ant. Jordan in his Ohio Report gives it as more abundant in the 
Ohio river drainage than in that of the lake. ‘‘ Lake Erie and 
Maumee river,’ Henshall, 1889; Lorain County, ‘‘common,’’ 
McCormick, 1892 ; ‘‘common throughout the Maumee basin, all 
waters examined (in Ohio) except Hoaglin creek,” Kirsch, 1893 ;

Branch,’ Williamson and Osburn, 1897; John’s creek at Water- 
loo, Huron river at Milan, Ashtabula creek at Ashtabula, R. C.
