Problems solved by technology

[0005] In order to overcome the disadvantages of poor effect of the existing bead nucleus treatment technology, high mortality rate and high rate of nuclei of pearl oysters, the purpose of the present invention is to provide a drug treatment method for bead nucleus, which has low operational requirements and will not affect shellfish. Man-made damage can effectively improve the nacre of pearls, reduce the mortality rate and spit-out rate of pearl oysters, increase the production of pearls and the economic benefits of aquaculture production, and promote the healthy development of seawater pearl culture

Embodiment 1

[0010] In terms of mass ratio, high-purity gelatin, tetracycline hydrochloride, polyvinylpyrrolidone PVP and vitamin C were selected, and the above reagents were weighed in proportions of 2%, 5%, 0.4% and 0.2%, respectively, and sterilized seawater was added to 1000 ml. Stir in a water bath at 50°C and dissolve overnight; heat the bead core (clam or clam shell into a round shape) in a 50-60°C incubator to a temperature of 50°C, take out the bead core, and use a paint sprayer to install the above-mentioned dissolved overnight The solution is sprayed on the surface of pearl nuclei, and at the same time, it is constantly turned to make the sprayed drug layer uniform, smooth and dry; it is vacuum-packed and transported to the pearl farm.

Embodiment 2

[0012] In terms of mass ratio, high-purity gelatin, tetracycline hydrochloride, polyvinylpyrrolidone PVP and vitamin C were selected, and the above reagents were weighed in proportions of 4%, 8%, 0.8% and 0.4%, respectively, and sterilized seawater was added to 1000 ml. Stir in a water bath at 50°C and dissolve overnight; heat the bead core (clam shell or clam shell into a round shape) in a 5060°C incubator to a temperature of 60°C, take out the bead core, and use a paint sprayer to fill the above solution dissolved overnight. Spray the surface of the bead nucleus, while constantly turning it to make the sprayed drug layer uniform, smooth and dry; vacuum pack, transport to the pearl farm, insert the pearl oyster with conventional nucleus insertion technology, and carry out postoperative recuperation and hanging.

Abstract

The invention relates to a medication method of pearl nuclei. The technical proposal adopted by the method for solving the technical problems thereof is as follows: high-purity gelatin, tetracycline hydrochloride, polyvinylpyrrolidone (PVP) and vitamin C are weighed respectively as according to the mass ratio of 2-4%, 5-8%, 0.4-0.8% and 0.2-0.4%, added with sterilized seawater to 1,000ml, stirred in water bath at 50 DEG C and dissolved overnight; the pearl nuclei (clam or tridacna shells are ground to be round) are heated in a 50-60 DEG C thermotank to the temperature of 50-60 DEG C, the pearl nuclei are taken out, the overnight dissolved solution is put into a paint sprayer, and the surface of the pearl nuclei is sprayed and continuously turned over to cause the sprayed drug layer to be even, smooth and dry; the pearl nuclei are packaged in vacuum and transported to a pearl cultivation farm, pearl-culturing oyster are inserted into the pearl nuclei by the conventional nuclei insertion technology, and then post-operation recuperation and hanging cultivation are carried out. The medication method of the pearl nuclei has the advantages of effectively improving pearl nacre, lowering the mortality rate and nuclei spitting rate, improving the pearl output and economic benefit of breeding production, simple using method, easy operation and remarkable effect.

Description

technical field [0001] The invention relates to a method for treating bead core drugs. Background technique [0002] The pearl farming industry is different from other aquaculture industries in that the purpose of farming is not for food, but mainly for the production of precious ornaments - pearls. Seawater pearls are commonly cultivated by mantle grafting method: manual surgery cuts a small opening in the visceral mass of the pearl oyster, implants the bead nucleus (the shell of mussel or giant clam is ground into a circle), and then cuts the mantle tissue into small pieces After being attached to the implanted bead nucleus, the small pieces of mantle proliferate through cell division, gradually wrap the bead nucleus to form a pearl sac, and then secrete nacre on the bead nucleus to produce artificial pearls (Wang Aimin et al., 2000). [0003] Due to the artificial incision of the pearl oyster during the cultivation of seawater pearls, causing damage, and implanting forei...
