Problems solved by technology

[0003] However, the current rough sea cucumber seed breeding mainly has the following two problems: 1. In the planktonic stage of the larvae, Chaetoceros mouvii, Isoflagellates, Phymophthora subcordiformis and Chlorella are used as bait. The water tempera

Embodiment 1

[0031] (1) Cultivation of ginseng:

[0032] Choose natural rough sea cucumbers with a weight of 150-400g or artificially cultivated rough sea cucumbers as parent-parasitic ginseng, and stock them in 10-20m 3 Cultivate in indoor cement ponds, stocking density is 10-15 heads / m 2 . Place 25cm×25cm, 5cm-high cement four-legged bricks on the bottom of the pool as concealment. Feed with sage algae powder, Apostichopus japonicus compound feed, aquatic yeast, sea mud and multivitamins, etc., once a day in the evening, and the daily feeding amount is 3-5% of the body weight. According to parts by weight, the feeding bait for ginseng includes 400-450 parts of sargassum powder, 400-450 parts of compound feed for ginseng ginseng, 100-200 parts of sea mud, 3-8 parts of aquatic yeast (generally 5 parts ) and 3-8 parts of multivitamins (5 parts are generally used). Generally, the ratio of sargassum powder, sea cucumber compound feed and sea mud is 4.5:4.5:1.

Abstract

The invention provides a holothuria scabra artificial seeding breeding method. The method comprises the steps such as parent holothurian cultivating, induced spawning, spawn washing and hatching, larva cultivating, seedling collecting and childish holothurian cultivating, wherein spirulina powder, marine yeast, aquatic yeast and bacillus serve as bait, not only are bait sources convenient, but also the investment of single cell culture facilities is saved, meanwhile, manpower needed by single cell algae bait culture is saved, the holothurian seedling cost can be greatly saved, and the popularization of the holothuria scabra seedling breeding technology is facilitated. The substitutive bait is adopted to replace living single cell algae, invested funds of seeding facilities can be saved by about 25 percents, the human input of seeding can be saved by about 30 percents, and the ratio of the seeding input to the seeding output 1:3. Induced spawning is performed on the two days before or after the first day and the fifteenth day of a lunar month, the good effect of two times of spawn sampling in one month is achieved, the induced spawning success rate is 83.3 percents, and the technical problem that the induced spawning difficulty of holothuria scabra parent holothurian is high is effectively solved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for breeding rough sea cucumber artificial seedlings. Background technique [0002] Coarse sea cucumber, scientific name: Holothuria scabra, is an animal of the genus Holothuria in the family Holothuria. Nutritional value, economic value and health care function, it is a real ecological healthy food. Internationally, rough sea cucumber is also an important tropical sea cucumber cultured species and a high-grade aquatic product for export. Distributed in the west from Port Natal to the Red Sea, east to the Caroline Islands, Fiji Islands, north to Japan, south to Australia, and Guangxi, Guangdong, Hainan and other places in mainland China, generally living on the edge of coastal reefs and Sandy bottom with fast tides and seaweed. As an important part of sea cucumber breeding, sea cucumber seedling cultivation technology has been widely carried out in coastal areas...
