Of the introduced species, three, the carp, the gold-fish and 

 the brown trout are of Eurasian origin. The quinnat salmon, 

 from the Pacific coast, seems not to have become established 

 here. The other introduced fishes are all from nearby Atlantic 

 and Great Lake States. 



To make a final comparison of the number of fishes in other 

 river systems or larger areas with the number found in our cir- 

 cumscribed territory, we find in the Connecticut River only 18 

 permanent species. Including all the anadromous and brackish 

 water fishes, 25 species occur in the easternmost county of 

 Maine. From the Neuse River in North Carolina, 55 species 

 are known, while Cayuga Lake basin harbors 60. 



As we go west into the Mississippi valley the number of 

 species vastly increases, even the smaller tributaries having 

 upwards of 50 species within limited areas, while from the 

 Wabash River 130 species are recorded.
