ABSTRACT:
An apparatus for collecting fish eggs comprises a conveyor for transporting fish with the upper half of each fish inclined obliquely upward, a pair of upper and lower conveyor belts for holding the tail of each fish therebetween during transport, a pair of upper and lower conveyor belts for holding the trunk lower half portion of each fish therebetween during transport, trunk support portions and fish back restraining frames arranged alternately on the lower trunk holding belt, a head cutter disposed close to the terminal end of the conveyor, a member for pressing the abdomen of each fish after its head has been cut off, and an operating mechanism for the pressing member. During transport on the conveyor, the eggs in the abdominal cavity of each fish move toward the tail of the fish under gravity, and the head is thereafter cut off by the cutter. During the subsequent transport operation, the fish has its abdomen pressed by the member, is bent rearward about the portion thereof held by the trunk holding belts and is prevented from being further bent by the restraining frame in bearing contact with the back of the fish. The member therefore fully exerts its pressure on the fish to completely squeeze out the eggs from the head cut-off face for collection.
