Method of embedding nuclei inside hyriopsis schlegeli for breeding oversized round-shaped pearls

Abstract

The invention discloses a method of embedding nuclei inside hyriopsis schlegeli for breeding oversized round-shaped pearls. Nucleus inserting is used once or twice. The method is characterized in that the nucleus inserting method includes the following steps: after a pearl breeding oyster opens and is added with a plug, and dirt inside the oyster is cleared away, using a wound needle to wound the position of half of the axe foot width and 40%-45% (counting from the back end, and the same below) of the axe foot length of the pearl breeding oyster to obliquely downwards pass a visceral mass towards a front end to wound horizontally, and then pulling out the needle in the position of 55%-65% of the visceral mass, and implanting a bead nucleus and cell bodies in the position of a wound, wherein the position of the implanted bead nucleus includes that a central point is in the position of 60%-75 % of the length of the visceral mass, the edge of the upper end of the bead nucleus adjoins the connecting position of an axe foot and the visceral mass, a nucleus sending needle is pulled out, the position of the wound is smoothed, and the plug is pulled out after inflammation is diminished in the wounds; after being operated, hanging and breeding the pearl breeding oyster in a repairing pool, after the wound heals, hanging and breeding the pearl breeding oyster in a breeding pool. Due to the facts that space in the visceral mass and the visceral mass positions of the oyster is large, an oversized pearl can be borne inside the oyster and cannot be squeezed. Therefore, oversized top-grade high-quality pearl products can be bred.

Description

technical field [0001] The invention relates to a method for nucleating and cultivating super-large-sized round pearls in visceral masses of chrysalis mussels, belonging to the technical field of agriculture and aquatic products. Background technique [0002] In the existing freshwater pearl production technology for pond butterfly mussel cultivation, a mature set of cultivation water area selection, operation preparation mussel cultivation, pearl cultivation pearl oyster surgical inoculation, pearl cultivation management, water quality regulation of cultivation water area and mussel disease prevention have been formed. Prior art, the advantage of this technology is: cultivate high-grade high-quality pearl in the mantle of pond butterfly mussel, existing problem and deficiency are: due to the limitation of mantle thickness, it is difficult to cultivate super-large-sized perfect circular nucleate in mantle Even if a large-sized pearl nucleus is implanted, it will be squeezed ...

[0002] In the existing freshwater pearl production technology for pond butterfly mussel cultivation, a mature set of cultivation water area selection, operation preparation mussel cultivation, pearl cultivation pearl oyster surgical inoculation, pearl cultivation management, water quality regulation of cultivation water area and mussel disease prevention have been formed. Prior art, the advantage of this technology is: cultivate high-grade high-quality pearl in the mantle of pond butterfly mussel, existing problem and deficiency are: due to the limitation of mantle thickness, it is difficult to cultivate super-large-sized perfect circular nucleate in mantle Pearls, even if they are implanted with large-sized bead cores, will be squeezed and deformed due to the unbearable mantle and the small space in the clam. Therefore, even if they can reach more than 15mm, they cannot meet the high-end high-quality standards of perfect circles.
