Fig. 120. White Perch. Morone americana. 



This excellent little fish of the fresh, brackish, and salt waters of our east 

 coast ranges from South Carolina to the maritime provinces of Canada. While 

 essentially an anadromous species it is often landlocked in fresh water. Its most 

 common and appropriate name is white perch, but in North Carolina it is called 

 "silver perch", "black perch", or simply ''perch". 



In Albemarle Sound, it is more abundant and more valuable than the yellow 

 perch, although scarcer than formerly; and in Currituck Sound it exists in 

 greater abundance than any other commercial species, The average weight of 

 those marketed is .5 to .75 of a pound, and the maximum weight is about 1.5
