Salvelinus alpinus (Linnaeus) 

 Salbling; Saibling (Introduced) 



Body moderately elongate, compressed, its greatest depth 

 two ninths of total length to caudal base; the caudal peduncle 

 short and stout, its least depth two fifths of length of head; 

 head rather short, its length contained from four and one third 

 to four and one half times in total length to base of caudal 

 (middle caudal rays). The body is somewhat elevated at the 

 nape and for a short distance behind it. Mouth large, the 

 maxilla reaching somewhat behind eye, its greatest width less 

 than one fourth of its length, the upper jaw one half as long as 

 the head; eye rather large, nearly equal to snout, one fifth of 

 length of head; interorbital space convex, one and one half times 

 diameter of eye; lower jaw very slightly projecting; vomerine 

 teeth in a very small patch on the head of the bone, lingual 

 teeth strong, teeth on both jaws well developed, those of the 

 mandible strongest; gill rakers short, straight, very slender, the 

 longest one half as long as the eye, 11 above and 14 below the 

 angle of the first arch. 



The dorsal origin is nearer to tip of snout than to base 

 of caudal, its distance from the snout equaling twice the 

 length of head; the dorsal base is as long as the postorbital 

 part of head; the longest dorsal ray is % two thirds as 

 long as the head, and nearly twice as long as the last ray. 

 Adipose fin twice as long as wide, as long as the iris, its origin 

 distant from base of middle caudal rays a space equal to length 

 of head without the snout; the fin is over the end of anal base. 

 Ventral midway between tip of snout and base of middle caudal
