Long"-nosed Sucker; Northern Sucker 



Catostomus caiostomus (Forster) 



The long-nosed sucker is one of the largest of the family, 

 reaching a length of 2 to 2\ feet, and a weight of several 

 pounds. It is found from the St. Lawrence River and the Great 

 Lakes westward in the Upper Missouri basin and to the Upper 

 Columbia, thence northward to Alaska; the most widely dis- 

 tributed sucker; but probably not occurring south of 40° north 

 latitude, except in West Virginia where recently obtained by Prof. 

 W. P. Hay. 



In the Great Lakes and northward this species is a food 

 fish of considerable value. It is usually taken in hoop or trap 

 nets, or gillnets. 



Its spawning time is in the spring, in most localities as 

 early as May.
