The Food of Fishes

Abstract

In a paper on the food of Illinois fishes published in the second bulletin of this Laboratory, the subject vvas treated in a general and cursory manner, the amount of material upon which that paper was based being insufficient for exact or detailed description. This paper contains an account of the food of the Acanthopteri of the State nearly or quite sufficient for the student of science and for  the practical fish culturist.   lt is still necessary only to study the food of specimens under a half-inch length and to test the value of the general conclusions reached by occasional examinations of fishes taken from other waters at other seasons of the year.
