Abstract
The object of the invention is to enable the mechanical processing in the usual manner without presorting, of fish caught in drift or stationary nets, a very high percentage of these fish thus being damaged at their heads. This is made possible in that the fish placed in troughs of a conveyor transverse to their longitudinal axis come into operational relationship on their path of conveyance with a circumferential surface of a driven rotational body moved to swing in the axial direction of the fish. Therein the head of the fish enters the wedge formed between a support surface of the conveyor and the circumferential surface of the rotational body so that the circumferential surface comes into contact with a head flank of the fish. By limiting the swinging movement of the rotational body by placing a thickness sensing element operationally related to a rotational body onto the fish the desired positioning for a beheading of the same is achieved.
