The Relation of Mollusks to Fish in Oneida Lake 199 
course with a disagreeable odor, specially in the Great 
Lakes. Individuals from the Ohio River and from: more 
southern streams are fairly good food fish, while in Texas 
Mr. Turpe considers it one of the most excellent of the fresh- 
water fishes, comparing favorably with black bass.’ 
There is reason to believe that this species would thrive in 
Oneida Lake. The molluscan genera Campeloma and 
Anodonta, principally used as food by the adult, are abund- 
ant in the lake and are not eaten, as far as known, by any 
other fish. The young, however, would enter into competi- 
tion with other young fishes for the chironomid and 
ephemerid larvee so largely eaten. The habitat conditions 
indicate favorable environments for these insect larvee and 
the introduction of this fish would probably not disturb to any 
extent the balance of the organisms.

Forbes (1888, a, p. 484) gives the food of the Ling as fol-

of crawfishes (Cambarus). The data for this specimen (420
