22 FISHES OF LORAIN COUNTY, OHIO. 



Quite common in the lake, ascending the rivers. . Kirtland 

 says that it appeared in Lake Erie in 1848, coming through the 

 newly-opened canal, and speaks of great numbers being killed by 

 the cold in the canal as a proof that they belonged in a warmer 

 climate. It is a very handsome but very worthless species. 



Family XI. SALMONID.zE. The Salmons. 



Fishes with abdominal ventral fins, two dorsal fins, the ante- 

 rior rayed, the other adipose, scales cycloid (with smooth edges), 

 and stomachs with many pyloric caeca, belong to this family. 



"In beauty, gameness, activity and size of individuals, differ- 

 ent members of this group stand easily with the first among fishes." 

 And by virtue of its wide distribution and abundance the 

 family as a whole rank among the first in economic importance. 



50. Coregonus clupeiformis (Mitchill). Whitefish. 



[Jord. Man. 183. O. St. Sitrv. 93.] 



Body oblong, compressed, more or less elevated according to 

 age, head small and short, loiver jaw shortest, tongue toothless, the 

 gill rakers long and slender , length 20-30 inches. Five or six pounds 

 is the weight of a good-sized fish, though occasionally one much 

 larger is taken. Mr. Nicholas of Vermillion reports one that weighed 

 19}^ pounds. Jordan in three different works gives the lateral line 

 as " 74." In the specimens that I have examined I have found only 

 one that agreed with this, one had 77, but those with 81 up to 85 

 were more common. 



Common in the lake, not detected in the streams. 



SI- Coregonus artedi Le Sueur. Lake-herring. 



[Joi-d. Man. 186. O. St. Surv. 96.] 



Slender, compressed, little elevated, greenish, sides silvery, 

 finely speckled with darker, lower jaw projecting. Length 18 

 inches. (See plate 7.) 



Very abundant in the lake, sometimes filling the pound nets 

 almost solid with fish. I have not detected it in the streams.
