Abstract: A system and method provide an intensive aquaculture system for producing caviar or other goods. The system has a photosynthetic subsystem to consume waste from a production species, a food production subsystem to consume the photosynthetic species and be eaten by the production species. Optionally, the food production species may be pelletized or otherwise refined before being consumed by the production species. While each subsystem may have its own water chemistry, gas scrubbers may be used to control gas levels among the subsystems. In one implementation, an enclosure is used with a sensor to measure the gas above the water in the photosynthetic species. Water and species may be transferred among the subsystems as desired. Multiple aquaculture systems may be used in combination to provide age-specific systems operating in conjunction with one another and distribute risk of disease or failure across multiple systems.

Abstract: A method and an apparatus for preparing an alimentary granular soft caviar similar to black (granular) caviar. The method involves the preparation of a mixture containing an albuminous colloid, water, and alimentary gelatin to form the grains, exposing the grains to tea water, dye-stuff, salt solution and gustatory components. The grains of caviar are obtained by supplying the mixture under pressure through gauged channels to a cavity with heated vegetable oil in its upper section, separating and washing the grains, tanning the grains in a tea extract, water washing, washing with salt solution, introducing to the product of a gustatory component in an amount not less than 10% of the total weight of the product and mixing the grains with vegetable oil. The albuminous colloidal solution is soymilk, foremilk of mammals, or a mixture of these components, a mixture of cow/soy milk, or whey of soy or cow milk. The grains are dyed by immersion in an extract from the rind of green walnuts.

Abstract: A method and an apparatus for taking out the viscera of a fish. A fish, the head of which is cut off, is conveyed by conveying belts and the belly of the fish is incised with a cutting blade. The fish, the belly of which has been incised, is caused to rise along a bone-supporting plate to make the position of the bone constant. The pointed end of a membrane peeling-off blade is inserted into the top portion outside a coelomic membrane of the fish to strip the coelomic membrane from the fish. Since the viscera of the fish is wrapped in the coelomic membrane, the viscera is taken out from the fish meat by stripping the coelomic membrane from the fish meat.

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: An apparatus for carrying out a method for gutting fish is provided, which comprises in combination a conveyor including a number of segments at given intervals in a direction substantially perpendicular with respect to its moving direction and operating at a given speed in a certain direction, a rotary cutter for cutting off a head of a fish placed and carried on the conveyor while the venter located within the segment leads and the head is projected from one side edge of the conveyor, a retainer for retaining the fish to be beheaded in place, a plate for forcing the dorsal region of the beheaded fish onto the conveyor by the action of a spring, a guide plate fixed at a position where it comes into engagement with a cut end of the beheaded fish forced onto the conveyor by the plate, and a guts squeezer member formed of an elastomer adpated to be forcedly slid over the venter of the fish from the anus toward the cut end, the fish being now in engagement with the fixed guide plate and forced by the plate.

Abstract: Single organs, such as the hard-roe sacks or soft-roe are removed from fish by placing decapitated fish in a coneyor having troughs that are advanced transversely to the longitudinal axis of the fish. The fish are conveyed with their belly leading and lying on their side. The fish are fixed by engagement in the region of their tail end portion. The gaining of the organs occurs by controlled movement of one pressing element, each, into the trough, so that the pressing element compresses the belly cavity progressively from the belly side starting at the tail-side end of the belly cavity and progressing toward the decapitation end of the fish.

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.
