PURPOSE: To provide an automatic feeding device for cultivation mainly composed of an automatic traveling/feed scattering device and an automatic charging device capable of uniformly scattering feed to a cultivation pond almost without the need of manual aid and automatically performing scattering at a prescribed time interval. CONSTITUTION: When a main body 1 approaches the border, photoelectric sensors 121 and 122 at a side part or a front part sense the approach and a control unit 12 controls the driving force of motors 111 and 112 and changes the course of the main body 1. In such a manner, while keeping the main body 1 in an almost fixed distance from the border, the cultivation pond is circulated once and the feed stored in a tank 13 is scattered. When the main body 1 is made to circulate once and passed under a mark rod 5, by signals from an upward sensor 123, the control unit 12 stops all the motors. Thereafter, the main body 1 is advanced along a guide pipe 4 by inertia force and stopped at a prescribed position by a stopping device 6 and a positioning device 7, and a battery is charged from an external power source. The electromagnet 60 of the device 5 is combined with a timer or the like, and when prescribed time elapses, the device 6 is opened, the control unit 12 simultaneously drives the motors and makes the main body 1 depart on a circumnavigation.
