FISHES OF NORTH CAROLINA. 



The log perch is the largest of the darters, reaching a length of 8 or 10 inches. 

 It is found from the Great Lakes region to Texas, and along the Atlantic slope as 

 far south as Virginia. In North Carolina it is known only from tributaries of the 

 French Broad. Jordan took one specimen in Swannanoa River near Asheville, 

 and Bean records one fine example from Cane River. The species inhabits clear 

 swift streams, and bites readily at the baited hook.

 slightly connected. Atlantic drainage system.
