The present invention relates to a device for inducing the bearing of a marsh snail which separately taming a parent snail and an offspring snail by separately preparing a parent snail storing unit floating on water in a water tank and an offspring snail storing unit installed on the bottom of the water tank. The device of the present invention comprises: a water tank in which water is stored; a parent snail storing unit which consist of multiple sections having storing spaces in each of the same so as to receive a parent snail fed therein in order to be tamed, has multiple holes which are formed on the bottom thereof in a smaller size than the parent snail, and floats on the surface of water in the water tank; a fixing body which fixes the parent snail storing unit while the same floats on the surface of water in the water tank; and an offspring snail storing unit which is installed on the bottom of the water tank and is installed at the bottom of the parent snail storing unit so as to store an offspring snail falling through the holes of the parent snail storing unit.
