Shell opening solution and method for pearl oyster and nucleus insertion method of shell opening solution

Abstract

The invention belongs to the technical field of pearl culture, and particularly discloses a shell opening solution and method for pearl oysters and a nucleus insertion method of the shell opening solution. The shell opening solution disclosed by the invention comprises seawater, fresh water and magnesium chloride, and the shell opening solution enables double shells of an oyster to be quickly opened in a short time without damaging the body of the oyster. The invention also provides a shell opening method for soaking the pearl oysters by adopting the shell opening solution. According to the shell opening method, batch treatment can be carried out according to the quantity of oysters which are required to open shells, the shell opening efficiency is high, and the survival rate of the pearloysters after resuscitation is high; and moreover, the invention also provides a nucleus insertion method comprising the shell opening method, by the nucleus insertion method, the nucleus insertion efficiency of the pearl oysters can be greatly improved, and the survival rate and the nucleus retention rate of the pearl oysters after nucleus insertion are high.

Description

【Technical field】 [0001] The invention belongs to the technical field of pearl cultivation, and in particular relates to a shell-opening solution for pearl oysters, a shell-opening method, and a core insertion method. 【Background technique】 [0002] Hepu pearl oyster (Pinctada fucata) belongs to the mollusk phylum, bivalve, pearl oyster order, pearl oyster family, and pearl oyster genus. It is the pearl oyster with the widest breeding area and the largest number of cultured pearl oysters in seawater. It is mainly distributed in Guangdong, In coastal areas such as Guangxi and Hainan, Hepu pearl oyster is an important shellfish for cultivating seawater pearls. The output of seawater pearls cultivated by using Hepu pearl oyster accounts for more than 95% of the total output of seawater pearls in the country. [0003] "Inserting the nucleus" is an important step in cultivating pearls. Before inserting the nucleus, the double shell of the shellfish needs to be opened first, and t...

Problems solved by technology

One method is to use an opener to insert into the double shell of the body, and then use an external force to open the opener so as to stretch the double shell of the shell body, and finally insert a wooden plug into the shell quickly to keep the mouth open, such as China Invention patent application CN105309341A, a method for seawater pearl cultivation by inserting nuclei and bead cultivation, and Chinese invention patent application CN 102246715 A, a method for cultivating night fluorescent pearl oysters. The shell body is dead and the efficiency of shell opening is low; another method is "shell shelling", that is, to arrange the shells neatly in the net frame upright, to suppress the opening of their double shells, and then put the net frame into seawater for soaking , and then open the net cage to take out the shellfish. At this time, the double shells of the shellfish are not bound by the space to open their mouths. Finally, the cork is quickly inserted into the opened shellfish body of the double shells to keep the mouth open. For example, Chinese patent application CN104920268 A A method for cultivating pearls with nuclei, but this method of opening the shell is complicated to operate, time-consuming and laborious, and has low efficiency
