Problems solved by technology

After years of research, the artificial cultivation of penguin pearl oyster free beads in my country has achieved initial success, but there are still problems such as high rate of nuclei spit out, high mortality rate, and low pearl formation rate, which seriously restrict the development of penguin pearl oyster industrial cultivation.
[0004] The ventral ridge of the left pocket of the penguin pearl oyster nucleus is small in size and is filled with developed intestinal tubes. Nucleation is implanted at

Embodiment Construction

[0019] The method for cultivating penguin pearl oyster free beads of the present invention will be further described below by means of specific embodiments:

[0020] A method for cultivating free pearls of penguin pearl oysters, comprising the following steps: Step 1: selecting materials, selecting 1 to 2-year-old pearl oysters with a shell height of about 10 cm, healthy penguin pearl oysters for breeding pearl oysters, and selecting 1-year-old pearl oysters with a shell height of 6-6 cm 7cm, healthy penguin pearl oysters are used as small oysters, wherein the pearl oysters need to be bolted, and the bolting treatment specifically includes densely and neatly arranging the pearl oysters in a square plastic frame, with the twisted part at the bottom, so that Do not open the mouth and keep it temporarily for 1-2 hours. Then, take out several of the shells so that the rest of the shells have room to open their shells. After the shells open naturally, insert wooden wedges; specifica...

Abstract

The invention discloses a method for cultivating a round pearl of a penguin pearl shell. The method uses the penguin pearl shell with height of about 10 cm as a pearl cultivating shell, the penguin pearl shell with shell height of about 6-7 cm or martensite as a small slice shell. The planted pearl core shall be small in diameter, and the core inserting part is a left bag core position of the pearl cultivating shell. The pearl cultivating shell uses the penguin shell with growth age for about one year and a half and the shell height of about 10 cm, and the penguin shell is quick in growth rate and big in core position; after the core plugging treatment, the death rate is low and the core remaining rate is high. The small slice shell uses the 6-7 cm small shell, and this specification of shell has thin outer sleeve film, and the produced small slice can be more tightly combined with the pearl core. Before plugging the core, byssus is sheared off by an oblique caliber, so as to reduce the influence on view and cutting opening in the course of plugging the core. Besides, by adopting the small bead core, the method avoids contacting and contaminating livers of the pearl cultivating shell in the course of planting the core, and improves the core remaining rate and the pearl quality.

Description

technical field [0001] The invention relates to the technical field of pearl cultivation, in particular to a method for cultivating free pearls of penguin pearl oysters. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the market demand for pearls has increased. At present, seawater pearls in China mainly come from the culture of Pinctada martensii. Breeding out pearl species is single, has restricted the development of pearl production. [0003] Penguin pearl oyster is a large pearl oyster with the characteristics of fast growth, high survival rate, and fast secretion of nacre. It is especially suitable for cultivating shelled pearls. Due to the special iridescent color of the nacre in the penguin pearl shell, a large number of researchers have been attracted internationally to study the cultivation of free pearls, but none of them have been successful. After years of research, the artificial culti...
