The Relation of Mollusks to Fish in Oneida Lake 228 
No glochidia were observed on the fish examined from Oneida 
Lake. The presence of a large naiad fauna indicates beyond 
doubt that large numbers of fishes are infected in the manner 
mentioned. Young Naiades (post glochidian) are rarely 
eaten by fishes. Forbes (1880, b, p. 481) noted them only 
in three sunfishes, a brook silversides, and a perch. The 
effect of glochidial infection on the general health of the fish 
has not been stated, as far as known to the writer.
