A kind of sea cucumber species ginseng ripening-promoting feed additive

Abstract

The invention discloses a feed additive for promoting ripening of sea cucumber seeds. The additive consists of the following components in percentage by mass: 5 to 10 percent of docosahexaenoic acid (DHA), 20 to 35 percent of eicosapentaenoic acid (EPA), 0.5 to 2 percent of astaxanthin, 2 to 4 percent of cholesterol, 0 to 10 percent of phospholipid, 5 to 15 percent of sand hopper powder, 0.5 to 1percent of vitamin A, 0.5 to 1 percent of vitamin C, 0.5 to 1 percent of vitamin E, 10 to 30 percent of pine needle powder, 5 to 15 percent of malt, 10 to 20 percent of egg yolk powder, 0.5 to 2 percent of globulin, 0.5 to 1 percent of erythrogenin and 0.5 to 1 percent of saccharicterpenin. The additive is suitable for promoting ripening of the sea cucumber seeds, and can obviously promote the gonad development of the sea cucumber seeds, quicken sexual maturity and improve the egg laying amount and the ripening ratio, fertility rate, hatching rate and sea cucumber seedling survival rate of the colony; and the additive does not contain hormone or antibiotics, has no pollution or no toxic or side effect, has low consumption, and is stable in raw material source, low in price and simple in production process.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a green sea cucumber seed ginseng ripening-promoting feed additive, which is especially suitable for promoting the ripening of artificially cultivated ginseng reaching mature age and individual size. Background technique [0002] In 2010, the annual output value of the national sea cucumber industry exceeded 30 billion yuan. Sea cucumber is the single species with the highest output value in my country's aquaculture, and has become a pillar industry of my country's aquaculture industry. At present, the mature species of ginseng needed for seedling cultivation of sea cucumbers mainly rely on fishing wild populations at sea. Due to the irregularity of large-scale fishing and the development needs of the sea cucumber industry, the stable supply of species of ginseng cannot be met, and due to the response of species to environmental changes irritative reaction, it is difficult to guarante...

AI Technical Summary

Problems solved by technology

[0004] The present invention starts from the optimal nutritional requirements during the breeding of ginseng, and provides a green ginseng ripening-promoting feed additive that meets the optimum growth and reproduction of ginseng and has good stability, avoids the use of chemical growth-promoting agents and hormone substances, and overcomes the need for ginseng. The problem of ginseng nutrition deficiency and low reproductive rate is aimed at enhancing the reproductive ability and hatched larvae quality of species ginseng, and maximizing their fertilization rate, hatching rate and survival rate
