In this part, the experimental analyses of the mechanisms of the social facilitation in feeding behavior of the guppy, Poecilia reticulata PETERS, are reported. The feeding rate was shown by the numbers of Daphnia pulex LEYDIG eaten during 2 hrs. The results obtained are as follows : 1. The social facilitation in the feeding behavior of the guppy was mainly evoked by visual stimuli. 2. The social facilitation of the feeding behavior in the guppy is likely to be the process by 'the presence recognition effect', rather than that induced by 'the learning effect' or 'the feeding behavior recognition effect'. 3. The size, number of individuals and movement of companions were effective as stimuli, and an increase in quantity of stimulus facilitated the feeding behavior. But, sex, body form, coloration and position of the companion had no or, if any, a very limitted value as a stimulus. 4. The fact that an increase of the feeding behavior resulted from the size and number of companions suggests the facilitation by 'the presence recognition effect' caused by the sensophysiological process. 5. The feeding rate increased as the number of stimulators increased up to 3,but never increased with more than 3 stimulators. Referring to literatures, the discrimination among the companion's numbers of 1,2 and more than 3,observed here, may be applicable in schooling fish species. 6. Lastly, a general view on some concepts on the social facilitation was given, and the meaning of 'the presence recognition effect' and application of the three processes to schooling fish specles were discussed.
