SALMON 



tingulshed from the first-mentioned by having blunter 

 teeth, a more pronounced fringe at the edge of the 

 suctorial disc, and more continuous dorsal fins. In 

 other respects it resembles its congener, and it may be 

 mentioned in conclusion that, after the all-important 

 time of spawning is at an end, Lampreys, as with Eels, 

 emaciate and die. 



Salmon. — Salmo salar (Fig. 31). Has obtained its 

 generic name of Salmo from the root of another Latin 

 word meaning = to leap, in reference to its well-known 

 habit of leaping falls, or weirs, when ascending rivers 

 to spawn. During the years that it is passing through 

 various stages, and according also to the processes it 

 undergoes, the Salmon is known by several diflFerent 

 names, and it will be as well to give a list of these in the 

 order in which they are conferred : — 



1. An Alevin. The Fry, or young fish, when first 



hatched. 



2. A Parr. When a few months old. From the 



old English parrert, to enclose, in reference 

 to the marks on the sides resembling the bars 

 of a fence. 



3. A Smolt. When it first visits the sea. Derived 



from an old English word, meaning shining, 

 in reference to the dress. 



4. A Grilse, or Peal. When it first returns from 



the sea.
