Embodiment Construction

[0018] 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.

[0019] 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 method is characterized in that a lot of larva is obtained by absorbing sperm and egg artificially or inducing spawning fertilization and the larva is bred in the hanging way in a sea area; at the stage when female scallops are mature, the hatchlings are separated and the mud is replaced based on the hatchlings growth situation, and the hatchlings are sucked out; at the stage of nucleus-inserting and bead-breeding, a surgery operation is applied on the female scallops, then the bead nucleus are inserted into the soft parts of the scallops; at the recuperation stage, the female scallops are put into a recuperation cage after the operation, and are bred in the hanging way in the calm sea area; at the bread-breeding stage, the female scallops after recuperation are put into a cage and are bred in the hanging way in the outer sea area where water flow is smooth; and at the pearl harvesting stage, the scallops are killed and the beads are taken out by dissection. According to the invention, the problems of low culture benefit and huge labor intensity lead by traditional crude and simple culture method are overcome; the culture of the seawater pearl is more scientific; and the culture economic benefit is more substantial.

Description

technical field [0001] The invention belongs to the field of aquaculture science and technology, and relates to a seawater pearl cultivation 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 irritable and irritable during menstruation and menopause, wearing a pearl necklace can play a better role in regulating and re...
