PCT No. PCT/FI89/00069 Sec. 371 Date Oct. 31, 1990 Sec. 102(e) Date Oct. 31, 1990 PCT Filed Apr. 12, 1989 PCT Pub. No. WO89/10061 PCT Pub. Date Nov. 2, 1989.The present invention relates to an apparatus for the orientation of fish with respect to the position of abdomen and dorsum. The fishes (6, 7) are thrown head first against an oblique, preferably curved guide element (5) in such a way that the center of gravity of the head (8) of the fish lies sidewards from the perpendicular to the guide element (5) through the contact point of the fish, due to which the fish turns into contact with the guide element (5) and into the same orientation with respect to the direction of abdomen and dorsum, irrespective of, whether the fish hits the guide element with dorsum or with abdomen.
