Example Embodiment
[0028] Embodiment 1: rich in carotenoids, the golden-yellow new line F 1 nurture
[0029] Time: April 2008, Location: Shantou University Nan'ao Linhai Marine Biological Experiment Station.
[0030]The species is 2 years old, with a shell length of 78.6mm, a shell height of 85.2mm, a shell width of 26.8mm, and a live weight of 78.9g. Through careful seed selection, single induction induction, single fertilization to establish family line, seedling cultivation, intermediate breeding and development, color purity inspection, new line screening and propagation, total carotenoid content detection, the operation steps are as follows:
[0031] 1) Carefully selected species: The selected female and male species must have golden shells, golden adductor muscles, golden mantles, 2 years of age, healthy, and fully developed gonads. 18, all species of shellfish from the same breeding group.
[0032] 2) Single induction of labor: After the scallops are dried in the shade for 10 minutes, ...
Example Embodiment
[0040] Example 2: Carotenoid-rich new golden-yellow scallop F. 2 nurture
[0041] Time: March 2009, Location: Shantou University Nan'ao Linhai Marine Biological Experiment Station
[0042] The difference from Example 1 is that the species of shellfish are 1-year-old shellfish and come from F 1 Family, shell length 58.5mm, shell height 62.6mm, shell width 20.8mm, live weight 35.2g. Through careful seed selection, single induction of labor, single fertilization to establish families and random mating within families to establish groups, seed breeding, intermediate breeding and development, color purity inspection, new line screening and propagation, total carotenoid content detection, Its operation steps are:
[0043] 1) Careful selection of seeds: the same as the operation step 1) of Example 1, 518 species of shellfish are all from F 1 Family 1-year-old shellfish.
[0044] 2) Oxygenation: the same as the operation step 2) of Example 1.
[0045] 3) Establish pedigrees and ...

Abstract
The invention relates to a culture method of a new golden-yellow strain of Chlamys nobilis rich in natural carotenoid, which comprises the steps of: seed selection, single individual induced spawning, family establishment by monogam insemination, offspring seed culture, intermediate breeding and cultivating, color purification check, new strain multiplication and continuous selective breeding and the like; and the new golden-yellow strain of the Chlamys nobilis rich in natural carotenoid can be cultured by two-generation directional selective breeding. The new strain has stable character, not only has golden-yellow shell, adductor muscle and pallium, but also is rich in the natural carotenoid; averagely, 98% of individuals have golden-yellow shells, 96% of individuals have golden-yellow adductor muscle, 99% of individuals have golden-yellow pallium, and the total content of the carotenoid is 4.4-13.7 times of that of groups not subjected to the selective breeding. The invention culture a new strain of shellfish from the angles of the sensed color and the nutrition; and the cultured new strain of Chlamys nobilis not only has beautiful color, but also is rich in the natural carotenoid, thereby achieving significant economic value, health care value and medical value and having broad market prospect.
Description
【Technical field】 [0001] The invention relates to a selective breeding and genetic improvement technology in the research of shellfish genetics and breeding, in particular to a method for cultivating a new strain of Chlamys farreri. 【Background technique】 [0002] Carotenoids, also known as lipochromes, belong to terpenoids. Usually refers to the 40-carbon hydrocarbons, that is, carotene, and the oxidized derivatives of carotene, that is, lutein. Carotenoids are the general term for these two types of pigments. Carotenoids are mainly synthesized by higher plants, algae and microorganisms, and exist in nature in the form of yellow, orange-red or red pigments. So far, more than 650 kinds of carotenoids have been found (Matsuno, 2001; Ren Yongxia et al., 2003). Animals cannot synthesize carotenoids by themselves, but animals can store them in their bodies by ingesting natural carotenoids from the outside world, so carotenoids widely exist in animals, plants and microorganism...
