Embodiment 1

[0038] Time: April 2008-April 2010, Location: Shantou University Nan'ao Linhai Marine Biological Experimental Station.

[0039] The shellfish is 1 year old, with a shell length of 58.2mm, a shell height of 62.4mm, a shell width of 20.2mm, and a live weight of 34.8g. Through seed selection, single individual induced labor, monogamous insemination to establish the F1 generation family, F1 generation larvae cultivation, F1 generation spat growth, and F2 generation new strains were cultivated, and the DHA content was determined to obtain a new strain of Chlamys farreri rich in DHA. The operation steps are:

[0040] (1) Species selection: In April 2008, 24 male and 24 female and male species of 1-year-old, healthy and well-developed gonads were selected, and the shell, adductor muscle and mantle were all orange in color. All species came from in the same breeding group.

[0041] (2) To induce labor for a single individual: After drying the female and male species in (1) for 10 mi...

Abstract

The invention relates to a cultivation method of a Chlamys nobilis new strain enriched with DNA (Deoxyribonucleic Acid) and an application thereof. The cultivation method comprises the following steps of selecting seeds, cultivating an F1 generation genealogy and cultivating an F2 generation new strain; and carrying out two generations of directional breeding to cultivate the Chlamys nobilis new strain enriched with the DNA. The invention further provides the application of the cultivation method in the cultivation of other shellfish new varieties. According to the cultivation method, the shellfish new strain can be cultured from the aspects of sensing, color and cluster, and nutrition; the cultivated Chlamys nobilis new strain has beautiful attractive color and cluster; a shellfish, an adductor muscle and a pallium are orange; in-vivo tissues are enriched with the DNA; and therefore, the Chlamys nobilis new strain has obvious economic value, health-care value and medical value, and has a wide market prospect.

Description

technical field [0001] The invention relates to a selective breeding and genetic improvement technology in shellfish genetic breeding research, in particular to a method for cultivating a new line of Chlamys farreri rich in DHA and its application. Background technique [0002] Docosahexaenoic acid (DHA), commonly known as "brain gold", is a long-chain polyunsaturated fatty acid essential to the human body. It is an important component of brain cell membranes, participates in the formation and development of brain cells, and has The extension of axons and the formation of new protrusions play an important role in maintaining the normal physiological activities of nerve cells and participating in the formation of brain thinking and memory. DHA is also the most abundant long-chain polyunsaturated fatty acid in retinal photoreceptors. It is an important component of the retina and plays an important role in promoting the development of retinal tissue, promoting the development ...
