Abstract: The present invention provides a cage farming apparatus. The cage farming apparatus includes: a buoy configured to float on the surface of the sea; a central structure configured to be seated on the bottom surface of the sea and to be connected to the buoy by a lifting rope; a floating means fitted around the lifting rope, and configured to be lifted along the lifting rope due to buoyancy or to be lowered along the lifting rope due to a load; an auxiliary structure configured to be located on the bottom surface of the sea and to be spaced apart from the central structure; a cage net configured to be located above the auxiliary structure and to be connected to the floating means by a connecting rope; and pulleys formed on the central structure and the auxiliary structure, and configured to guide the connecting rope through its movement.
