The present invention relates to a buoy which is installed to display a boundary area of a fish farm. In a fish farm buoy comprising a floating body manufactured by foaming, the floating body is formed by being divided into an upper main body and a lower main body in an assembling structure so as to overcome size restriction of the foaming. Each of the upper main body and the lower main body is formed by foaming with an expanded polypropylene (EPP) material having light-weight and high elasticity and strength. The floating body comprises an expanded part formed to protrude toward a side on an outer circumference so as to maintain a horizontal state in the state that the floating body is floating on the water surface. Thus, the light-weight buoy has improved durability and improved structural stability. |
