Farming method of selenium-enriched fish

Abstract

The invention belongs to the technical field of aquaculture, and particularly discloses a farming method of selenium-enriched fish. According to the farming method of the selenium-enriched fish, the fish is fed with selenium-enriched feed in percentage by the body weight of the fish in a staging manner, and fish pond management is managed, wherein the selenium-enriched feed is prepared according to the following main steps: mixing selenium-enriched rice bran, selenium-enriched corn, silkworm chrysalis, sesame, selenium-enriched rapeseed oil, an additive and inorganic salt in certain parts by weight, crushing, sieving, puffing, granulating, drying, spraying with oil, and cooling; the additive is prepared from codonopsis pilosula, areca nut, turmeric, rosa laevigata, white houttuynia cordata, astragalus membranaceus, wild jujube seed, agastache rugosa, oligosaccharide, galactooligosaccharide, mannan oligosaccharide and the like in certain parts by weight. According to the farming method of the selenium-enriched fish, the fish is reasonably fed with the selenium-enriched feed with rich and comprehensive nutrition, high selenium content and a good selenium-supplementing effect, so that the selenium content of fish meat is effectively increased, and people can achieve the purpose of supplementing selenium to human bodies through consumption of the fish meat, and the problem of selenium shortage in the human bodies is effectively solved.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of aquaculture, in particular to a method for breeding selenium-rich fish. [0003] 【Background technique】 [0004] Selenium is one of the essential trace elements for the human body. It has a strong antioxidant effect. It can remove lipid peroxides and free radicals in the body to protect cell membranes, improve immunity and disease resistance, and protect the body against harmful foreign substances. More than 40 human diseases are related to selenium deficiency. Selenium supplementation can prevent and cure related diseases. Selenium supplementation has gradually become a consensus among people. However, about 72% of the world is lack of selenium, and the source of selenium-enriched food is very limited. In the selenium-rich areas, the people in Se-du, who have been eating a large amount of food from non-selenium-rich areas for a long time, only one-third of the people whose blood selenium content has re...

Problems solved by technology

However, the current fish farming methods are generally fed single or mixed common feeds such as corn, grass powder, bean cake, rice bran, etc., which cannot achieve the purpose of increasing the selenium content of fish.
