lican ("08, p. 156) states that in the a(|uaritiii) it is "nKire hardy than any otlier 

 minnow," and Mather ( '86. ]>. 32) tells us that "it is a hvely fish, usually in swift 

 water, hut thrives in the acjuariuni." Kunninf,' water would jjroltahly need to be

 water, which has also been Hankinson's experience with adults of this species.

.hnjIiiKi Xolcs. The bait qualities are well expressed by Kentlall and dolds- 

 borouj,'h ( '08. p. 34 ) : "The larger individuals of this little si)ecies are hardy and 

 make an attractive bait for salmon and trout. They may be caught with a small 

 hook and worm bait, but this is a slow method. The most satisfactr>ry method is 

 by minnow traj)s: a small seine or dip-net is sometimes elTective in br<K)ks that 

 are clear enough, where the ingenuity of the fishennan may indicate ways and 

 means of <lriving the fish into the nets."

 Found but once in ( hieida Lake, but abundant in the small tributary streams on the 

 north shore l)etween Constantia and North Hay. It is a characteristic sjiecies of 

 swift waters, as is indicated by its scientific name.

Iliihitut. This fish thrives in swift water>. A single sixrinun ( No. 500^ 

 3,'<i inches long, was taken in < )neida I -ike. all the others from br(Mik>. in the most 

 rapid water (Fig. _'_'o|. In the small immiIs at the foot of the swiftest water the

 shores of l.ikes. is in harmony with its presence in the l)each-|xKils at (ieorgian Hay. 

 l-ike Huron, where, as Hensley ("15. p. jn\ says. "It is practically the only fish 

 inhabiting those [kmiIs, though those open to the outside water sometimes contain 

 other siKcits. The fish lurks under stones and is only taken by strategy." In the
