  • Patent number: 5836266
    Abstract: An apparatus is used to connect shellfish to a culture rope, which includes a shellfish transfer unit (5, 23, 29, 31) that transfers shellfish in a predetermined direction, shellfish (7) being transferred, two by two, in parallel upstanding orientation with their ear end portions (7a) down. The shellfish transferred by the shellfish transfer unit is stopped at a predetermined stop position defined by stoppers (39, 41). A culture rope (51) is supplied to a space between the ear end portions of two shellfish in the stop position. An ear spacer (50) and a pair of shellfish supporting pads (43, 45) cooperate each other to secure the scallops in the stop position where they are subjected to the piercing operation by a piercing unit and the pin-inserting operation by a pin inserting unit so that the ear end portions of two scallops held in parallel relation in the stop position are connected to the culture rope positioned and extending therebetween.
