Abstract: An apparatus includes a pressing device that elastically presses the abdomen of fish body which has been decapitated and which is conveyed in a downstream conveying direction, from the vicinity of a tail of the fish body to a neck thereof. The pressing device is both flexible and elastic and is rotated and driven about a rotary axis. Thereby, ovaries are removed from the abdominal cavity of the fish body. Since the pressing device is rotated and driven about the rotary axis, the abdomen of the fish body conveyed in the downstream conveying direction can be continuously pressed from the tail to the neck. Since the pressing device is flexible and elastic, it does not press the fish body with an excessively large force, and the ovaries can be removed smoothly from the abdominal cavity without destroying the fish body.

Abstract: In a fish processing machine consisting of fish body feeder, decapitator, belly filleting and viscera removing device, and dark-colored flesh removing device, the fish body feeder is designed to transport the fish body supplied in lying position by feeding onto the tray while aligning the back-belly direction uniformly, and the dark-colored flesh removing device is intended to separate the ordinary flesh and dark-colored flesh of the fish body efficiently to remove the dark-colored flesh.

Abstract: A fish processing machine includes a fish body feeder, a decapitator, a belly filleting and viscera removing device, and a dark-colored flesh removing device. The fish body feeder is designed to transport fish bodies onto trays while aligning all of the fish bodies in a uniform direction. The dark-colored flesh removing device separates the ordinary flesh and dark-colored flesh of the fish body efficiently.

Abstract: An apparatus for collecting roe comprises a conveyor for conveying a fish body such that a cut section of a decapitated fish body is downward. The tail of the decapitated fish body is held, and a roe collector is disposed at a position abutting against the tail side of the tail of the abdomen of the fish body along the conveying route of the decapitated fish body by the conveyor, and is thrust elastically in a direction approaching the conveying route in a manner free to dislocate in a direction crossing the conveying direction. The decapitated fish body is thereby conveyed with the cut section downward, having its tail pinched by the conveyor. Along this conveying route the roe collector is provided, and the caudal side of the abdomen of the fish body is elastically pressed. As a result, the fish eggs is elastically pressed. As a result the fish eggs are squeezed out of the cut section of the decapitated fish body.

Abstract: An apparatus for collecting roe has a conveyor which grips decapitated fish bodies in a lying position, with the tails of the fish bodies set in one common direction. A plurality of projections are provided on the conveyor for holding the fish bodies in this position. The abdomens of the fish bodies are directed downstream with respect to the conveying direction. A roe collector is provided adjacent the conveyor. A collecting member abuts against the abdomens of the fish bodies as the fish bodies are conveyed by the fish body conveyor. This collecting member rotates and is driven about a rotational axis which extends in a direction crossing with the conveying direction. The collecting member is further thrust elastically upstream in the conveying direction to contact the tail ends of the fish bodies. The decapitated fish bodies are thereby conveyed by the conveyor in a fixed position due to the holding projections.
