Abstract: [Problem] To provide a fish egg processing apparatus capable of performing predetermined processing on fertilized eggs with higher efficiency, and collecting proper fish eggs. [Solution] When a housing recess that houses fish eggs one by one is conveyed to a predetermined processing position, and a capillary is raised and lowered to inject a gene solution, the housing recess is imaged from a direction that intersects a depth direction and a conveying-in direction, and an injection operation by the capillary is controlled by determining, along a possibility determination flow, whether to inject a predetermined substance into each of the fish eggs before processing, based on a previously determined condition.

Abstract: A soft spherical object conveying apparatus according to the present invention comprising: a water tank into which at least one soft spherical object is introduced; a conveying rotary member that rotates in the water tank and has a peripheral part provided with a plurality of housing recesses housing each one of the soft spherical objects; a guide member disposed along part of the peripheral part of the conveying rotary member in the water tank; and a removing roller that rotates on an upstream side of the guide member in the water tank in a rotation direction of the conveying rotary member, such that a part of the removing roller opposed to the peripheral part of the conveying rotary member moves in a direction away from the guide member.
