<p>A device for arranging fish in uniform head-tail alignment comprises a rotating gripping device of radially arranged pincer-like gripping elements. These form a vertical slot into which the fish led tail end first are introduced. Following the rotation of the gripping device the gripping elements are held closed in a region of a stationary sector of each one revolution so that the tail fin is grasped and the fish carried along thereby. After passing the highest point of the revolution of the gripping device the fish turns over under the effect of gravity and is then released head end leading. Fish led head first cannot enter the slot because of their thicker heads and are passed on directly.</p> |
