Problems solved by technology

[0004] At present, during the production process of pearl oyster implantation and nucleation, the operated mother oyster is directly moved to the sea area for recuperation. Due to the instability of environmental factors such as water temperature, water flow, and the type and quantity of bait organisms in the sea area, the survival rate of the oyster oyster is low. Low, high denucleation rate, long time for transplanted cell flakes to form pearl sacs, slow secretion of nacre, low rate of high-quality pearls, most farmers harvest 1-2 catties of pearls per 10,000 shellfish planted with nuclei, and the rate of high-quality pearls is only 15 % or so, farmers are unprofitable or even operating at a loss. It is very necessary and urgent to improve the rate of high-quality pearls cultivated through technological innovation.

Abstract

The invention discloses a postoperative low-specific-gravity seawater recuperation method for pinctada martensii after nucleus implantation, and belongs to the technical field of aquaculture. The method comprises the basic steps of preparation of a postoperative recuperation pond of pinctada martensii, preparation of recuperation water, selection and nucleus implantation of pearl breeding shellfishes and recuperation management of the pearl breeding shellfishes, wherein in the nucleus implantation and pearl breeding processes of pinctada martensii, healthy pinctada martensii is selected for nucleus implantation and pearl breeding and transferred into the indoor or outdoor pond for low-specific-gravity seawater recuperation after an operation, and after the recuperation is finished, pinctada martensii is transferred to a sea area for breeding of the pearl breeding shellfishes according to a conventional method. By means of the method, pinctada martensii is subjected to postoperative recuperation, the nucleus maintaining rate of the operative shellfishes is high, the rate of high-quality pearl is high, the pearl quality and economic benefit of the pearl breeding shellfishes can be improved, and the method is suitable for postoperative recuperation of the pearl breeding shellfishes of pinctada martensii, is easily applied and popularized in production enterprises and has significant economic and social benefits.

Description

technical field [0001] The invention relates to a low-specific-gravity seawater recuperation method for Pinctada martensii after nuclear clam implantation, belongs to the technical field of aquaculture, and is suitable for the production of pearls of Pinctada martensii implanted with nuclei. Background technique [0002] Martensii pearl oyster ( Pinctada martensii ) Also known as Hepu Pearl Oyster ( Pinctada fucata ), is the main species of seawater pearl cultured in my country, and the pearls it produces account for more than 95% of the seawater pearl production. The pearls cultivated with Pinctada martensii are called "South Pearl". And Hainan, Guangdong is the main producing area. At present, the main problems in the production of "South Pearl" in my country are the degradation of pearl-growing varieties, the deterioration of the breeding environment, and the obsolete breeding technology, which lead to high mortality of pearl-growing oysters, low nuclear retention rate,...
