56. Pungitius pungitius (Linnaeus), ninespine stickleback (fig. 41) 



The ninespine stickleback is common to the shoal areas of Lake Superior. It was encountered 

 in a relatively few streams scattered along the entire south shore. This fish is too small to retain 

 in the traps. 



It is not uncommon in the spring and early summer to find this species a considerable dis- 

 tance upstream from Lake Superior. The weir on the Chocolay River, Marquette County, Mich., is 

 about 15 miles above the mouth of the stream, but 64 ninespine sticklebacks were captured at 

 this weir in 1962.
