 Von Behr trout by the United States Fish Com- 

 mission, and the Loch Leven trout [Salmo leven- 

 ensis^, the first named having been brought from 

 Germany, and the other from Scotland. Many 

 authorities question the differentiation between 

 these two species, although the presence of red 

 spots on the brown trout, and the absence of them 

 on the Loch Leven fish, is a strongly marked char- 

 acteristic. The brown trout with its ability to, 

 and practice of, eating our small native brook 

 trout (fontinalis), has lost popularity among those 

 who seek for desirable fish to plant. When in- 

 troduced, they should be in waters where our 

 native trout do not live. The brown trout, like 

 the rainbow, are adapted to waters of a higher 

 temperature than our brook trout, and although 

 the brown trout possess no game qualities equal to 

 those of fontinalis or the rainbow, it may be 

 planted in private waters v/here the species may 

 live supreme, thus giving variety to the fishing. 



The Loch Leven trout (Salmo trutta levenensts) was 

 brought from Scotland about fifteen years ago, and
