A rearing device has: a disk-shaped turntable where the rearing containers are attached in an orderly manner; and a feeding unit and a water injection unit arranged above the rearing containers along revolving paths thereof. The rearing device repeats feeding and water injection every time the turntable revolves. The rearing container preferably has a cylindrical shape with a conical or semispherical bottom section and gaps at an upper section of a side wall for drainage.
