48 THE SPORTING FISH 



the varieties are numerous, and in some instances 

 present such considerable differences, as to have 

 led to their being classified as separate species — 

 as, for example, the Loch Leven and Gillaroo 

 varieties. 



The universally admitted species are — 



The Common, or Yellow Trout {Salnio fario), 



and 

 The Great Lake Trout (Salmo ferox). 



In regard to each of these the specific charac- 

 teristics are given in detail at the end of the several 

 articles ; but a few general observations here will 

 possibly enable the reader to distinguish them 

 without the necessity of resorting to a minute 

 comparison. 



1. As regards localities. — The Common Yellow 



Trout breeds indifferently in brooks, rivers, 

 and lakes, whilst the Great Lake Trout is 

 never found except in or close to lakes, and 

 these almost always large and deep. 



2. The flesh of the Great Lake Trout is generally 



a sort of orangey-yellow, and that of the com- 

 mon Trout pink or white, according to the 

 nature of the water and the condition of the 

 fish, the spots also on the former are usually 

 surrounded by a paler ring, sometimes of a 

 reddish tint.
