The Relation of Mollusks to Fish in Oneida Lake 27 
This work is an effort to place on record an intensive 
study of one group of animals — the Mollusca — and to 
show how this group is economically valuable in carrying on 
fish cultural operations. If is likewise an attempt to indi- 
eate some of the biological interrelations between this group 
and the animals and plants with which it comes in contact. 
Tt is now known that this class of animals can be artificially 
introduced into bodies of water, in which they are naturally 
lacking, and the time is not far distant when this procedure 
will become common practice. It is the earnest wish of the 
writer that the information set forth in this report may 
awaken more of an interest in this group of animals and 
encourage more students to take up their study.
