The present invention is to improve the manufacturing method of a buoy consisting of a foam foam generating a buoyancy in a buoy where a rope mounting groove is formed in which a rope can be mounted around the cylinder and a cover member covered on the outside of the foam. It relates to a method of manufacturing a buoy for aquaculture, which is excellent in durability by impact and has good surface smoothness. That is, in the manufacturing method of the buoy which is provided in the form of a cylinder and is formed with rope mounting grooves at both ends in the longitudinal direction, forming a foamed foam having a contact groove located inside the rope mounting groove formed in the bugu, Cutting the foam foam on the same horizontal line along the outer direction from the bottom surface of the foam groove, and forming a cut on one side of the annular ring in which the foam foam is cut and divided, and outside the foam foam. The cover member to be covered is formed by forming a pair of half-segmented cover members having a rope mounting groove formed thereon and divided end portions facing each other, and fitting the annular rings divided in the foam 100 into the insides of both cover members. And attaching a deterioration-preventing tape to the middle portion in the longitudinal direction of the foam, and covering members on both sides of the foam that have undergone the above steps, respectively. Characterized by a method of manufacturing a fisheries farming buoy which comprises a step of sandwiching both ends of the ends to be placed at positions facing each other, and injecting and bonding a synthetic resin solution to the parts of the ends of the ends of the cover member. Is done.본 발명은 원기둥의 둘레에 로프가 장착될 수 있는 로프 장착홈부가 형성되어 있는 부구에 부력을 발생시키는 발포폼과 그 발포폼의 외부에 커버부재가 씌워지는 구성으로 이루어진 부구의 제조방법을 개선하여 충격에 의한 내구성이 우수하고 표면 평활도가 좋은 수산 양식용 부구의 제조방법에 관한 것이다.즉, 원기둥 형태로 구비되고 길이방향 양측단 내측에 로프 장착홈부가 형성된 부구의 제조방법에 있어서, 상기 부구에 형성된 로프 장착홈부의 내부에 위치하는 밀착홈이 형성된 발포폼을 성형하는 단계와, 상기 발포폼의 밀착홈
