Utah Lake Trout 237 



Nevada, into which they may have been intro- 

 duced. 



The trout of Utah Lake {Salmo clarkii virgi- 

 nalis, subspecific name from the Latin, "like a 

 virgin ") is a striking illustration of the adapta- 

 bility of fish to widely different chemical condi- 

 tions of water. This trout not only lives in an 

 alkaline lake, but thrives there, growing to a 

 weight of twelve or more pounds ; its back is 

 covered with small black spots from head to the 

 fleshy part of the tail, where they are not so 

 numerous, and the scales are slightly larger than 

 those of the greenback and Rio Grande trouts. 

 It is found in the lakes and streams in the Wa- 

 satch Range, particularly in Bear, Provo, Jordan, 

 and Sevier rivers and in Utah Lake. On the 

 trout of the last-named waters the dark spots are 

 few and small and are located almost entirely 

 on the back ; they are also paler in color 

 than is general with fish of the same species 

 found in the streams ; but, like all forms of the 

 cut-throat series, different colorations may be 

 found in nearly every fish examined. The Utah 

 Lake trout is said to be a good fighter on the rod, 

 and is highly prized as an edible fish in the sec- 

 tions of its habitat.
