PURPOSE: A shelter assembly structure for culturing abalones in a marine cage is provided to culture abalones under the sea and to allow easy assembly of shelters. CONSTITUTION: A shelter assembly structure for culturing abalones in a marine cage comprises a main body (11), a lid (14), a feed inlet (16), partition walls (18), a protrusion (20), and combining holes (22). The main body has a rectangular body shape or a box shape. The lid is assembled into the opening of the main body. The feed inlet is formed so that feed can be inserted into the main body. The partition walls are installed so that abalones can inhabit thereon. The protrusion protrudes outwards from the main body and has a predetermined height. The combining holes penetrate the protrusion in the same direction.
