    摘要： A method for rapid low-salted pickling of aquatic products is disclosed, which includes preliminary processing of raw materials, bacteria-reducing treatment of plasma activation gas, marinade adding and plasma treatment, cyclic bacteria-reducing treatment with the plasma activation gas and vacuum pickling. The marinade adding and plasma treatment include respectively injecting the marinade and plasma working gas into a tumbler, with a flow rate of ionic working gas injected into the tumbler of 1.5-2 L/min and a flow rate of a pickling solution of 0.5-0.8 L/min: and at the same time, starting a plasma power supply, and performing low-temperature plasma treatment on the aquatic products to be pickled, with a plasma treatment voltage of 12000-15000 V, a current of 60-80 mA, a frequency of 8-10 kHz, which is a second bacteria-reducing treatment, with plasma treatment time of 15-20 min.

    摘要： The present invention provides an anti-fouling and anti-corrosion agent for the marine steel structure surface and preparation method thereof. The emulsion is made of raw materials at the following mass ratios: 1100 to 1500 parts of a polyurethane monomer, 1000 parts of polyether glycol, 200 to 400 parts of an alcohol chain extender, 100 to 250 parts of a hydrophilic chain extender, 200 to 400 parts of epoxy resin polyols, 100 to 150 parts of triethylamine, 400 to 1000 parts of an acrylate monomer, 1000 to 1500 parts of a graphene oxide-protamine composite emulsion, and 5 to 20 parts of an initiator. The solvent-free and composite film-forming resin emulsion of the present invention has both anti-fouling and anti-corrosion functions, which applies to a production of a green and environmental marine coating and protects the marine steel structure surface to prevent from organism attachment and sea water corrosion.

    摘要： A continuous trawl fishing method includes: by dragging a fishing net in water through a vessel, carrying out trawling operation so that catches to be fished enter a cod-end of a fishing net tail; then tractioning and moving the cod-end so that a sucking fish tube of a vacuum sucking fish pump reaches into the cod-end; and a tube mouth of the sucking fish tube contacting the catches in the cod-end to run the vacuum sucking fish pump to suck the catches from the cod-end into the collection tank through the sucking fish tube, and the catches in the collection tank being then transferred and frozen or directly processed. The fished catches of the present invention are obviously improved in indicators such as the stiffness time and the number of the first-grade fresh fish and so on. The histamine content is obviously reduced and the catch quality is improved.

    摘要： A method for preserving aquatic products at sea includes the following steps: an on-board refrigeration system is used to refrigerate the antifreeze solution, and the antifreeze solution is used as a main cold source, and temperatures at centers of fish bodies drop rapidly to achieve rapid cooling and reduce activity of endogenous enzymes and inhibit proliferation of microorganisms by direct or indirect heat exchange with captured catches. The antifreeze solution contains edible alcohol, propylene glycol, glycerol, calcium chloride, sodium chloride, amino acids, Antarctic krill protein hydrolysate with average molecular weight of 50-100 KDa, surfactant and water, and the mass percentage of each component is as follows: edible alcohol 15%-30%, propylene glycol 10%-30%, glycerol 2%-15%, calcium chloride 1%-10%, sodium chloride 3%-10%, amino acid 0.1%-0.15%, Antarctic krill protein hydrolysate 0.01%-0.3%, surfactant 0.005%-0.5%, and the balance is water.
