Embodiment Construction

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] 1 Parental selection

[0024] 1) Among the 2,000 pairs of mussels aged 4-5 years, select the clams whose body length is more than 15cm, the shells are intact, the abdomen is bulging, the mussels are strong and plump, the external branchial flaps are not damaged, and the adductor muscles are strong and powerful. , whose shells are thick and strong against pressure, and have obvious growth advantages compared with mussels of the same age, 500 pairs of mussels were selected as candidate parent mussels;

[0025] 2) Apply the living body identification technology of the nacre of the triangular sail mussel, first use the cold shock method to place the triangular sail mussel on ice for about 30 minutes, then use a shell opener to gently insert it betw...

Abstract

The invention relates to a method for artificially breeding purple nacre strain hyriopsis cumingii, which comprises the following steps of: (1) selecting parent clams, namely optimizing the cold shock method of the hyriopsis cumingii and a dental mirror in-vivo observational technique, establishing a loss-free, quick and accurate hyriopsis cumingii nacre color in-vivo identification technique, and screening the parent clams by combining hyriopsis cumingii pearl-breeding properties; (2) breeding small clams, namely hanging and inbreeding male and female parents in a water body without heterogenic sperm interference according to the inbred combination, and independently breeding from mating, seedling parasitizing, seedling growing to pearl breeding; (3) breeding pearl-breeding clams, namely sending offspring of each female clam after pearl inserting to a plurality of culturing farms and independently breeding; and (4) breeding the purple nacre hyriopsis cumingii strain, namely determining early stage of pearl inserting operation and later stage of pearl breeding as critical periods of breeding and optimizing small clams and pearl-breeding clams. The method has the advantages of visual breeding properties, accurate identification, and capability of breeding the purple nacre strain hyriopsis cumingii and improving the color purity and yield of pearls.

Description

technical field [0001] The invention relates to a method for artificial breeding of a purple nacre strain of Trigonaus mussels, which belongs to the technical field of aquaculture. Background technique [0002] The nacreous shells of Hyriopsis cumingii are mainly white and purple. During production, we found that the purple nacre strain grows faster and secretes nacre more vigorously, and the pearls bred as small clams and pearl-bearing mussels are also larger, rounder, and darker in color. Pearls are formed by implanting pearl mussel mantle cells into pearl mussels, forming pearl sacs in the pearl mussels, and then the pearl sacs secrete nacre; it has been proved that the pearl mussels that supply the mantle cell fragments determine the color of the nacre the color of the pearl. Therefore, shell nacre color is one of the important traits of pearl oyster breeding. [0003] At present, the breeding work of S. sinensis mainly focuses on the pearl mussel yield and the partic...
