Embodiment 1

[0025] a. Collection of ginseng

[0026] In January, sea cucumbers from 11 geographical groups were collected, namely Zhangzi Island, Exchange Island, Fuzhou Bay, Zhuanghe Shicheng Island, Lvshun, Changxing Island, Guanglu Island, Yantai, Jinzhou, Yingkou and Dandong coastal areas. The total number of individuals over 2.5 years old is about 3,000, and the average weight is 456g. See Table 1 for details.

[0028]

[0029] The transportation method is determined according to conditions such as transportation distance, time, and temperature. The transportation time is within 3-4 hours and directly transported in an incubator; if the transportation time is longer, add about 1 / 3 seawater to a polyethylene bag, and pack 2-4 sea cucumbers per liter of seawater, then tie the mouth of the bag tightly and put it in Transport in a foam insulated box, and add ice packs to control the water temperature if necessary.

[0030] b. Culturing of ginseng

[0031] After the gins...

Embodiment 2

[0045] Others are the same as in Example 1, except that in the b step, the parent ginseng is intensively cultivated, and the combined feed A is used for intensive cultivation 45 to 20 days before spawning. The components and weight percentages of the combined feed A are 70 to 90% of sea mud. %, adult shrimp feed 6-10%, sargassum powder 2-5%, yeast powder 0.5-1%, spirulina powder 0.5-1%, 20-15 days before spawning, use combination feed B for intensive cultivation, The components and weight percentages of the combined feed B are 60-80% of sea mud, 10-15% of adult shrimp feed, 5-10% of sargassum powder, 1-1.5% of yeast powder and 1-1.5% of spirulina powder.

[0046] During the entire process of intensive cultivation of ginseng, no drugs are used, and scientific management and reasonable nutritional ratio are used to meet the health and intensive cultivation of ginseng. The body weight and gonad ratio of the pro-ginseng after nutritional fortification were all improved, see Table ...

Abstract

The invention discloses a high strength selecting and cultivating method of excellent stichopus japonicus seeds. The high strength selecting and cultivating method comprises the steps of carrying out cultivation, spawning or spermiation promotion, and hybridization on parent stichopus japonicuses from at least four different geographical groups, and carrying out selective breeding at different degrees in different periods according to a quantitative genetics method. By combining two traditional and effective methods of hybridization breeding and selective breeding, the invention preserves excellent properties of the stichopus japonicus and also avoids inbreeding; because the cultivated stichopus japonicuses have excellent properties of different groups, the cultivated stichopus japonicuses have the advantages of fast growth speed, strong stress resistance and the like; and the invention not only realizes seedling pre-culturing of the stichopus japonicus to meet market demand in advance, but also prolongs an effective growth period of the stichopus japonicus within a year, shortens cultivation time, and improves economic benefit; therefore, the inveniton is suitable for large-scaled factory production.

Description

Technical field: [0001] The invention belongs to the breeding technology of aquatic animal seedlings, in particular to a method for cultivating pro-ginseng of different geographical groups, promoting their oviposition, ejaculation, and hybridization, so that the cultivated sea cucumber seedlings have fast growth speed and stress resistance. A high-intensity selective breeding method for high-quality sea cucumber seedlings that have the advantages of strong sex and are suitable for large-scale industrialization. Background technique: [0002] The body wall of sea cucumber Apostichopus japonicus (Selenka) is thick and soft, rich in collagen, acidic mucopolysaccharides and sea cucumber saponins, and has high nutritional and medicinal value. The main economic category. In recent years, with the increase of people's demand for sea cucumbers, the intensity of harvesting has gradually increased, resulting in a sharp decline in the resources of sea cucumbers in my country. Therefor...
