The present invention relates to a buoy for fisheries. The present invention is configured to have a main body (10) and end portion bodies (20 and 20). The main body (10) and the end portion bodies (20 and 20) are respectively configured to have main body cases (12 and 22) which are formed from a hard material, and filling materials (14 and 24) which are filled in the main body cases (12 and 22). A coupling hole (16) and a coupling projection (26) are formed so as to be coupled with each other at corresponding positions of the main body (10) and the end portion bodies (20 and 20). A locking groove (17) and a locking rib (27) are formed at the corresponding positions of the main body (10) and the end portion bodies (20 and 20). In the locking rib (27), a guiding inclined surface (28) is formed so as to be inclined in order to be oriented in the direction in which the end portion body (20) is rotated so as to be coupled to the main body (10), and a locking surface (28) is formed in an upright manner on the opposite side. A connection tool (30) is mounted around the outer surfaces of the main body (10) and the end portion bodies (20 and 20). A connection ring (34) is present in the connection tool (30) for connection with the outside.La présente invention concerne une bouée pour pêcheries.
