Kendall: Fishes of Maine. 3 
qualities is questionable. To the writer it seems that if the 
native fish have become scarce, if possible, it alone should be 
propagated for such waters and the native stock thus restored. 
If non-indigenous species are introduced, especially if the 
native form is already on the decrease and the foreign fish 
particularly hardy and vigorous, the alien will doubtless 
thrive at the expense of the native, if the waters are suited 
to the introduced form. Even if the native stock is not 
waning, the introduction of another struggler for existence 
is liable to upset the balance of nature that previously existed. 
There is no dearth of lakes in Maine, which are as well 
adapted to lake salmon as the few that are famed for their 
superb trout. If possible, these few trout lakes should be 
maintained and the others replenished with salmon and non- 
native trout. 
Aside from pike perch, black bass, carp and goldfish, all 
of the introduced forms belong to the salmon family which 
are represented by a number of species from Europe and the 
west. 
The following lists respectively include the foreign and 
American species not native to Maine that have been intro- 
duced. Only one, the small-mouth black bass (Micropterus 
dolomiew) has become sufficiently established to be admitted 
asa Maine fish. In the following lists the asterisk (*) indi- 
cates those which have been reported from one or more local- 
ities since their introduction.
