Problems solved by technology

The tissues and organs around the nucleus of penguin pearl oyster are different from other pearl oysters of the genus Pinctada in structure. The silk glands of penguin pearl oyster are well developed, and the silk produced is thick and hard in a rod shape, squeezing the space of the nucleus; The growth of penguin pearl oysters, this situation will become more and more serious, and the thick and hard filaments will greatly reduce the success rate of nucleus implantation

Embodiment Construction

[0022] refer to figure 1 , the first is the basic group establishment (G0). The degree of genetic variation in the base population directly affects the genetic progress and sustainability of breeding. In view of the fact that the wild populations of penguin pearl oysters in the coastal waters of my country are not clearly differentiated and have rich genetic diversity, we used the first-generation cultured population bred from the wild population in Hainan as the basic population, and selected individuals with missing or fine silk as the breeding parents. The first generation of breeding populations with missing or fine silks were selected as parents from the breeding populations of wild populations, because the farming environment of the breeding populations was unified, and the characters were clearly differentiated, so it was easy to find individuals with missing or fine silks; while the wild populations caught It is often the individuals with strong fixation and well-deve...

Abstract

The invention discloses a breeding method for excellent pteria penguin, taking cultivation of pteria penguin with byssus deletion or minuteness as a breeding target. The method comprises: firstly breeding a Hainan wild population to breed individuals which are excellent in character in the first generation and establishing a family system through balanced nest type mating; and then further carrying out screening according to an experimental result of nucleus insertion and pearl culture to gradually cultivate the excellent variety of pteria penguin with byssus deletion or minuteness. The method disclosed by the invention can be used for effectively improving the survival rate of nucleus insertion and pearl culture, the remained nucleus ratio and the excellent pteria penguin rate, so that the method has a good application prospect.

Description

technical field [0001] The invention relates to a method for breeding fine penguin pearl oysters, in particular to a method for cultivating good varieties with lack of silk or fine grains. Background technique [0002] At present, my country's pearl production is mainly through the cultivation of Pinctada martensii, but due to the poor quality of the pearls produced, the high cost of breeding, coupled with industrial planning or tourism development, the industry has shrunk sharply in recent years, and the annual production of seawater pearls in the country has been less than 2 tons. (The peak output reaches 25 tons), so the development of large-scale pearl shellfish farming is the only way to improve the efficiency of my country's seawater pearls and enter the high-end jewelry market. [0003] The pearls produced by the nacres and mother-of-pearls are high-grade pearls in the international jewelry market and have high economic value. Since the end of the 1970s, my country ha...
