Embodiment 1

[0053] In a freshwater fish breeding base, 60 days after the fish fry were put in, they started feeding organic selenium-rich fish feed. The fish feed consists of the following:

[0054] 5 parts of the aforementioned corn flour and 5 parts of wheat flour, 10-20 parts of imported fish meal, 10-20 parts of chicken meal, 15-20 parts of 43% soybean meal, 1-2 parts of phospholipid oil, 1-2 parts of refined fish oil, 1 part of Xinpeptide protein ~2 parts, 1~2.5 parts of molasses yeast, 1~1.5 parts of allicin, 10~15 parts of peanut cake, 3~3.5 parts of additives, made into fish feed, and fed with organic selenium-rich fish feed until the fish grow up and go on the market. Sampling and measurement showed that the total selenium content in the selenium-enriched fish group was around 200 μg / kg, and the proportion of organic selenium was about 95%.

Embodiment 2

[0056] In a freshwater fish breeding base, 60 days after the fish fry were put in, they started feeding organic selenium-rich fish feed. The fish feed consists of the following:

[0057] 19 parts of the aforementioned corn flour and 6 parts of wheat flour, 10-20 parts of imported fish meal, 10-20 parts of chicken meal, 15-20 parts of 43% soybean meal, 1-2 parts of phospholipid oil, 1-2 parts of refined fish oil, 1 part of Xinpeptide protein ~2 parts, 1~2.5 parts of molasses yeast, 1~1.5 parts of allicin, 10~15 parts of peanut cake, 3~3.5 parts of additives, made into fish feed, and fed with organic selenium-rich fish feed until the fish grow up and go on the market. Sampling and measurement showed that the total selenium content in the selenium-enriched fish group was around 800 μg / kg, and the proportion of organic selenium was about 92%.

Embodiment 3

[0059] In a freshwater fish breeding base, 60 days after the fish fry were put in, they started feeding organic selenium-rich fish feed. The fish feed consists of the following:

[0060] 14 parts of the aforementioned corn flour and 7 parts of wheat flour, 10-20 parts of imported fish meal, 10-20 parts of chicken meal, 15-20 parts of 43% soybean meal, 1-2 parts of phospholipid oil, 1-2 parts of refined fish oil, 1 part of Xinpeptide protein ~2 parts, 1~2.5 parts of molasses yeast, 1~1.5 parts of allicin, 10~15 parts of peanut cake, 3~3.5 parts of additives, made into fish feed, and fed with organic selenium-rich fish feed until the fish grow up and go on the market. Sampling and measurement showed that the total selenium content in the selenium-enriched fish group was around 1200 μg / kg, and the proportion of organic selenium was about 90%.

Abstract

The invention discloses an organic selenium-enriched fish and a cultivation method thereof. The selenium content of the organic selenium-enriched fish is 300-2000mu g / kg, and more than or equal to 80%. The cultivation method of the organic selenium-enriched fish comprises the step of feeding selenium-enriched forage according to the normal ingestion quantity of the fish after 60 days when fish fry is fed. The selenium-enriched forage comprises the components based on parts by weight as follows: 5-20 parts of corn powder, 5-10 parts of wheat powder and 53-88.5 parts of normal feeding forage, wherein the selenium content of the selenium-enriched forage is within the range of 400-1000mu g / kg. The fish is enriched with selenium and is uniform in whole contents. After the method is adopted, the proportion of organic selenium in the fish can be improved, and the standardized and large-scale production can be realized.

Description

technical field [0001] The invention relates to selenium-enriched aquatic products, in particular to an organic selenium-rich fish and a method for cultivating the organic selenium-rich fish, belonging to the technical field of aquaculture and its cultivation. Background technique [0002] Selenium is an essential trace element for humans and animals. It has a variety of important biological functions. When used in aquaculture, it can remove free radicals in aquatic animals, resist oxidation, improve immunity, and make animals more energetic. [0003] Selenium-enriched agricultural by-products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology is a hot area of ​​research and development by scientists. [0004] Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium is poorly absorbed by humans and animals, and has a high ris...
