Integration double-purpose efficient bead breeding method of penguin pearl shell and nucleus sending device thereof

Abstract

The invention relates to a Pteria penguin one-body two-use high efficient pearl cultivation method. Firstly, a core feeder is used for implanting a pearl core used for cultivating a dissociated pearl in the visceral sac of the Pteria penguin which is cultivated well; then the Pteria penguin in which the pearl core is implanted is put back to the culture water area for cultivating for a period of time; and a molding core which is used for cultivating blister pearl is implanted under the pallium of the Pteria penguin; the Pteria penguin in which the cores are implanted is put back to the culture water area for pearl cultivation; after the mature of pearl cultivation, the dissociated pearl is harvested from the visceral sac of the Pteria penguin and the blister molding pearl is harvested under the pallium. In the invention, as the one-body two-use high efficient pearl cultivation method for cultivating the dissociated pearl by implanting the core in the visceral sac and cultivating the blister pearl by implanting the core under the pallium in the visceral sac of the Pteria penguin by twice core implanting is adopted, the yield of pearl cultivation is improved efficiently, and the economic benefit is high. As the core feeder which consists of an outer tube, a core feeding needle and an adjustment device is adopted, the core implanting is safer, the orientation is more correct, and the working efficiency is high.

Description

technical field [0001] The invention relates to a method for cultivating pearls, in particular to an integrated dual-purpose and high-efficiency method for cultivating pearls of penguin pearl oysters and a nuclei feeder used therefor. Background technique [0002] At present, in the cultured pearl production of marine penguin pearl oysters, it is generally a single method of planting mold cores under the mantle to cultivate shelled pearls of various shapes or a single implantation of bead cores in the visceral sac to cultivate free pearls, so that The pearl output is not very high. So far, there is no culture technique for cultivating pearls while planting nuclei in the visceral sac and under the mantle of penguin pearl oysters. And the existing method of planting mold cores under the mantle to cultivate pearls with shells is mainly to cultivate semicircular pearls with shells.

Problems solved by technology

[0002] At present, in the cultured pearl production of marine penguin pearl oysters, it is generally a single method of planting mold cores under the mantle to cultivate shelled pearls of various shapes or a single implantation of bead cores in the visceral sac to cultivate free pearls, so that Pearl production is not very high. Up to now, there is no culture technology to plant nuclei in the visceral sac and under the mantle of penguin pearl oysters while cultivating pearls

And the existing method of planting mold cores under the mantle to cultivate pearls with shells is mainly to cultivate semicircular pearls with shells. In order to fix the semicircular mold cores in the shells under the mantle, shell drilling is usually used. Pull the wire at the bottom out of the shell to fasten the mold core to the shell. In this surgical method, the mantle attached to the shell must be pushed into the inner end of the shell before the operation can be performed. Due to the large area of ​​shrinkage of the mantle and the cumbersome operation, it takes a long time , high mortality rate after operation

There is also the existing visceral sac nucleation and cultivation of free pearls, which is an immature surgical method. Its operation method is the same as the nucleation method of Pearl oyster martensii for cultivating conventional seawater pearls, but due to the visceral mass of penguin pearl oyster The bead nuclei are small and lush, and the bead nucleus is held by a traditional nuclear feeder (a negative pressure nuclear feeder composed of a handle and an arc-shaped suction cup), and delivered to the nucleus through the upper side of the visceral silk. The operation is difficult. Even when the bead nucleus is delivered to the nucleus and returned to the nucleus delivery device, the sucker of the nucleus delivery device will cause great trauma to the viscera, and the bead production is low. , foreign countries have not formed large-scale production

In addition, the existing nuclei delivery devices cannot adjust the length of the needle head by using different specifications of bead nuclei according to the size of the visceral sac of different pearl oysters, so that the bead nuclei are also prone to fall off during operation, which is undoubtedly a problem for users. The operation brings some inconvenience, and it will also affect the positioning accuracy when planting the nucleus, so it is difficult to meet the requirements of the majority of farmers
