PURPOSE: A porous complex fish-breeding ground for shallow seas is provided, which enables macroalgae living at various water depths to reside depending on the vertical height of an incline. CONSTITUTION: A porous complex fish-breeding ground for shallow seas comprises: a main body(10) made of porous material in which a space is formed and an incline(15) formed in the top of the body in order to form a living space for macroalgae living at different water depth layers; an opening portion(25) which is formed to circulate sea water between the internal space of the main body and the outside; a net body(40) installed at the internal space of the main body; and through holes(17) through which seawater is circulated to the internal space. |
