CHAPTER XXII. 



Distribution of Fish Good Places. 



HILE an accurate knowledge of the 

 distribution of each and every kind 

 of fish is not essential, the angler 

 will be interested to know approxi- 

 mately how far the range of certain 

 fishes extends, and if he contemplates 

 going to some other place where he is 

 unacquainted, he will naturally want 



to know what kinds of fish he is most likely to find there: 

 Also, if there is a vacation or a fishing trip in prospect he 

 will want to know of the most favored localities. 



It is impossible to give accurately the range of each and 

 every species of fish for this is not known, even to naturalists. 

 Therefore, in most cases the distribution as given can not be 

 taken as the extreme limit of the district in which the fish 

 is found, for sometimes some certain fish will be found in 

 waters far removed from its natural range, and in other 

 cases there may be a large district, embracing several states 

 well within the boundaries of this fish's habitat, in which 

 no such fish are found. This may be due to one or more of 

 several causes. In many cases man has aided nature in dis- 

 tributing the various fishes by introducing western fishes 

 into eastern waters, or in placing eastern fish in waters 

 west of the Rockies, or even in bringing fish from Europe. 

 In this way fish may become widely distributed, yet great 

 spaces intervene. Again it is believed that various fishes 

 were scattered over a great range during the Glacial Period, 

 by being carried frozen in ice from far to the northward.
