19. COMMON CHUB 



SEMOTILUS ATROMACULATUS (Mitchill) 



At Lake Maxinkuckee this fish is confined practically to the 

 small tributary streams. . Numerous specimens varying in length 

 from 1 to 9 or 10 inches were obtained in each of the inlets, per- 

 haps most numerously in Aubeenaubee Creek; and a few were ob- 

 tained in the Outlet. In all of these little streams it pushes well 

 toward the head, and good-sized examples may be found where the 

 stream is but a few inches deep. Their favorite place, however, 

 is in the deeper, more quiet pools of these small streams. Though 

 they can endure a relatively high temperature and water which is 

 not very pure, they are often so crowded in these pools that the 

 water becomes poorly aerated and quite impure, and the fish be- 

 comes infested by various sorts of psorosperms and other para- 

 sites. These, however, rarely seem to prove fatal, and when the 

 fish are removed to favorable surroundings they speedily recover. 



The Common Chub reaches a length of 8 to 10 inches and is 

 one of the fishes quite sure to be found on the small boy's string. 

 It is one of the most voracious of the minnows and the sum total of 

 sport which it brings to the youth of the land is no doubt quite 

 as great as that which better fish bring to these same boys when 

 no longer young. But while the mature angler no longer seeks the 

 festive chub for its own sake, he nevertheless finds it a very useful 

 fish, for when he would land the wall-eyed pike, great pike, or 

 muskallunge, he finds no better bait than this same Chub ; the larger 

 ones for these species and smaller ones for black bass. The Chub
