The invention discloses a tridacna larvae artificial breeding method capable of improving the survival rate during proliferation and releasing. The method includes the steps of: performing selection and treatment on tridacna larvae for artificial breeding, and transporting the treated tridacna larvae to a sea area for proliferation and releasing; taking the tridacna larvae out of a flowing water bin, performing semi-buried treatment on the taken tridacna larvae in a calcium carbonate-material releasing base, then putting the releasing base with the buried tridacna larvae in a mesh cage rack with a lid, fixing the mesh cage rack on the bottom of the sea, and keeping the distance between the mesh cage rack and the slack tide water level at 3-15 meters and the distance between the mesh cage rack and the bottom surface of a seabed base at 30 cm or above; when the length of shells of the tridacna larvae grows to 6 cm or above, removing the tridacna and mesh cage rack, putting the removed tridacna and mesh cage rack in a coral reef area which has smooth water flow, light intensity of 6,000-12,000 LX and flat parts for growth, cleaning covering matter in time in a typhoon season, performing recovery and fixation on rollover tridacna bases, and eliminating harmful organisms. Through the tridacna larvae artificial breeding method capable of improving the survival rate during proliferation and releasing, the survival rate of the tridacna larvae can be improved effectively, and technical support can be provided for proliferation of the tridacna resource and ecological restoration of coral reefs in China.

The invention discloses a seed producing method for a tridacna crocea strain with bluish violet pallium. According to the method, in order to shorten the cultivating period of the new tridacna croceastrain, the parent screening rule is adopted for the first time; the theory that blue iridocyte in the pallium of tridacna develops, and consequently the pallium shows bluish violet is adopted in combination; multiple times of parent selection is adopted, blue iridocyte homozygotic type parents are obtained, the parents breed offsprings again next year, and the 100% tridacna crocea strain with thebluish violet palliu is obtained. The strain is attractive in appearance, the economic value is improved by 4-5 times, a new product is provide for a seawater ornamental aquarium market, and a new way is also provided for tridacna variety breeding. According to the seed producing method, the breeding period of the tridacna color new strain is shortened to 2 years from 5-6 years, the seed production period is greatly shortened, the breeding risk is reduced, the breeding benefits are increased, and the new path is provided for new variety breeding. The seed producing method has the advantages of being high in feasibility, high in practicality and the like.

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, stirredin 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.
