A machine for gathering oysters from an oyster bed, comprises a chassis (1) on which are carried a motor (2) and a gearbox (3). Two uprights (4) support endless treads (5) and the forward portion of the chassis supports an inclined frame (6) on which are mounted gathering members constituted by two adjacent circular flexible discs (7) each secured centrally to a rotatable axle (8). The discs are disposed above a fixed inclined comb (11) adapted to raise oysters sunk in the soil and/or distributed over this latter during movement of the machine so that the oysters will be seized during rotation of the discs (7) by flexible projections (10) arranged in star shape and projected rearwardly, the rotation of the axles (8) and the forward movement of the machine being obtained by drive belts connected to the gearbox.
