In laboratory experiments, characteristics of feeding behavior of  Coregonus peled larvae (fries) were studied. The mean speed of swimming of feeding larvae increased proportionally to their size, amounted to 1.65 of the body length per second and depended on the dimensions of both feeding objects and of the larvae. The influence of physiological saturation in hungry larvae was manifested during the first 5 minutes of feeding .The values of potential (maximal) speed of prey consumption in various size groups of larvae are estimated. On the basis of feeding characteristics it is concluded that the minimal concentration of preys at which the peled larvae during the first days can completely ensure their feeding requirements is within the limits of 10
