Embodiment Construction

[0007] The seawater pearl culture method of the present invention is divided into the stage of pearl oyster artificial seedling cultivation, mother oyster cultivation stage, seed insertion and pearl cultivation stage, recuperation stage, pearl cultivation stage, and pearl harvesting stage.

[0008] In the artificial breeding stage of pearl oyster. The nursery work begins with the selection of shellfish, that is, according to the production needs, select some mature individuals with strong body, full gonads, as broodstock, and use the method of dissection to artificially absorb sperm eggs or induce spawning and fertilization to obtain a large number of larvae. When the embryos develop After about 19 hours, count the number of larvae according to the density of 1-2 / ML in the culture water body, move them to the nursery room for cultivation, add water for the first 3 days, then drain and irrigate freshly filtered seawater every day, after changing the water, put in an appropri...

Abstract

A seawater pearl culture artificial seedling growing and mother pearl recuperation method comprising the following steps: in a pearl shell artificial seedling growing phase, the seedling growing work starts by pearl shell selection: selecting mature individual shells with strong shell body and plump sexual glands as parent shells according to production needs, employing a dissection method to artificially absorb sperm eggs or inducing egg laying fertilization so as to obtain mass larva, and moving the larva into a seedling growing chamber for cultivation; in a mother shell breeding phase, after seedling sea area hanging culture and before nuclear insertion: frequently checking seedling cages, removing mud and sea bottom marine life, timely separating seedling and changing mud according to seedling growth conditions, and absorbing the seedlings; in a recuperation period: placing the mother shells into a recuperation cage after operation. A conventional rough simple pearl breeding method is low in cultivation benefit, and large in labor working intensity; the seawater pearl culture artificial seedling growing and mother pearl recuperation method can solve the said problems, is more scientific in breeding, and can provide more obvious economic benefits.

Description

technical field [0001] The invention belongs to the field of aquaculture science and technology, and relates to a seawater pearl cultivation method, in particular to a seawater pearl cultivation artificial seedling cultivation method and a female oyster recuperation method. Background technique [0002] Seawater pearls are an ancient organic gemstone produced in seawater pearl shellfish and pearl molluscs. They are produced due to endocrine action. Seawater pearls contain calcium carbonate, calcium oxide, calcium phosphate, calcium sulfate, magnesium, manganese, Copper, iodine, phosphorus, strontium, lead, sodium, potassium and other elements and more than a dozen amino acids are composed of a large number of tiny aragonite crystals. Seawater pearls have the functions of calming the nerves and calming convulsions, clearing heat and benefiting yin, improving eyesight and detoxification, closing the mouth and promoting muscle growth in medicine. Especially for women who are i...
