Abstract

A device for sorting fish into uniform head-tail alignment is characterized by a truncated conic disc driven rotatingly about a horizontal axis, which disc, with its corundum-coated smaller frontal surface in connection with a gripping surface fixed to the frame of the device and opposing the frontal surface in the region above the axis, forms a gripping gap into which fish supplied with their tail end leading are introduced with their tailfins. Due to the rotation of the truncated conic disc the tail part of the fish is entrained by frictional engagement. During that process the fish is gradually placed on its tail so that a shift into the head-first position occurs, in which position the fish is set free at the end of the gripping surface.
