A portable fish cleaning assembly includes a platform that has a drink aperture, a tool aperture, a plurality of hook apertures and a pair of storage holes each extending therethrough. A pair of grapples is each removably coupled to the platform. Each of the grapples releasably engages a top pier rail having the platform being horizontally oriented on the top pier rail. In this way a fish can be positioned on the platform for filleting the fish. A pair of legs is each pivotally coupled to the platform. Each of the legs extends downwardly from the platform when the legs are positioned in a deployed position. In this way each of the legs abuts horizontal pier rails thereby retaining the platform in the horizontal orientation. A clamp is pivotally coupled to the platform to engage the fish for retaining the fish on the platform for filleting the fish.

A revolutionized tuna process according to this invention generally comprising the steps of thawing of frozen tuna, de-heading and degutting, fileting, de-skinning, cleaning of the de-skinned tuna filet, pre-cooking, cooling, packing of the cleaned and pre-cooked tuna loin, and sterilizing the packed tuna loin or freezing the tuna loin. Not only does the process according to this invention reduces the energy utilization by half, it also significantly reduces the time required for cooking and cooling. Therefore, the whole processing time is significantly reduced from at least 8.0 hours in the conventional process to less than 30 minutes.

A method and apparatus for filleting fish to produce high yielding fillets from relatively short bodied fish in the size range of about 600 grams to about 3.5 kilograms dependent on species. The method and apparatus are designed to be capable of handling salmon, tilapia, trout, arctic char, barramundi, snappers, walleye pike, striped bass and similar species where the rib follows the contour of the belly cavity. Further, the method and apparatus incorporate belly opening and eviscerating components prior to subjecting the fish to a backbone removal system so that the fish need only be headed, but not gutted, before introduction into the machine.

The invention provides a gutting device for gutting a fish along its abdominal cavity. A blade for cutting the fish open, and a shielding element are movably mounted on a controllable movable arm. The shielding element has a blunt tip, and it is arranged for being in: 1) a retracted position, where the shielding element allows the blade to cut the fish, 2) a tracking position, where the blunt tip of the shielding elements is inside the abdominal cavity of the fish, so as to track the end of the abdominal cavity of the fish, and 3) a shielding position, where the shielding element is pushed upwards by contact with the end of the abdominal cavity at a genital opening of the fish, thereby shielding the blade from further contact with the fish. This provides a precise method for without unintentionally damaging the fish.

A method for ecological utilization of silver carp, including the pretreatment of silver carp and the process of making canned fish surimi. The fish meat of silver carp is processed canned surimi. The fish heads and bones are heated and undergo enzymatic hydrolysis by enzymes, and the residues of the filtration are prepared for fish bone powder. A filtration membrane is used to reduce the volume of the filtrate to 50% of fish surimi and then the filtrate is frozen to ice. The frozen part can be added to fish surimi. The transparent part from membrane filtration was used to produce protein powder or ingredients for beverages. Fish offal can be used to produce protein liquid fertilizer. Fish scales and skins can be used to produce collagen. The method adopts ecological utilization, which makes the silver carp meat used effectively, including its processed wastes. The method is a closed cycle process such that that no pollutants or wastes are discharged during the process.

The present invention relates to a method, a system and an apparatus for treating food items. Such method and device may, for instance, be used to cool down food items, bleed freshly slaughtered fish and treat live fish against parasites. The device and method of the present invention further uses temperature differences and agitation to tread food items. A method for reducing or eliminating sea lice from salmon fish, said method comprising: a) transporting the salmon fish from a reservoir and the feeding salmon fish in liquid into the tubing of a first pumping device, said liquid being at a temperature from +15 to +28° C., b) transporting the salmon fish in liquid through the tubing of the pumping device at a first set time period for treatment in said liquid, c) feeding the salmon fish out of the first pumping device, d) separating the liquid from the salmon fish, and e) transporting the salmon fish back to the reservoir, wherein the liquid media from the pumping device is redirected after separation from the salmon fish in step d) through a heat exchange element back into the pumping device for continued treatment of further salmon fish, and wherein the temperature difference between the liquid used in steps b) and the reservoir is more than 15° C.

Gutting machine for fish, comprising a conveyor belt to receive fish, where the fish is placed with the abdomen facing a number of cutting and cleaning tools for gutting and cleaning of the fish when it is transported on said conveyor belt, in which said conveyor belt is equipped with a number of holding devices where respective holding devices are adapted for firmly holding the fish, and that one or more barriers arranged adjoining said conveyor belt are adapted to slow down the movement of the fish until the fish is firmly held in a respective holding device and is brought by the conveyor belt in its direction of movement. Also described is a method for gutting the fish in a gutting machine.

A device and method configured to jet pressurized liquid from hemal arch of fish into arteries and veins to perform instantaneous fish body blood removal, thereby cleansing the blood vessel interior. The device jets pressurized liquid into hemal arch from severed fish tail to perform fish ikijime (quality-preserving quick kill). A pressure applying device applies pressure to and discharges liquid and a hose conveys the pressurized liquid discharged from the pressure applying device. A valve connected to the hose opens and closes the flow path of the liquid and a nozzle jets the liquid when the valve is in open state. The valve opens or closes the flow path in response to a button being pushed down or pulled up. The nozzle is formed to taper from a large diameter base region toward a tip region, and tip region center hole diameter is formed thin.
