Embodiment 1

[0022] A method for culturing selenium-enriched sea prawns in freshwater, comprising the following steps:

[0023] (1) Preparation of selenium-enriched feed: 150-250 parts of selenium-enriched corn with a selenium content of 15-20 mg / kg and 100 parts of selenium-enriched soybeans with a selenium content of 10-15 mg / kg were washed, dried and ground respectively Form into granules with a particle diameter of 0.5mm, mix evenly, add 100 parts of traditional Chinese medicine additives, and prepare selenium-enriched feed;

[0024] (2) Shrimp pond construction: build a new shrimp pond, and after 2 days of exposure to the sun, enter 20cm of water at the bottom of the pond. Use quicklime to sprinkle the whole pond to remove wild fish and shrimps and eliminate pathogenic microorganisms; after 15 days of desilting the pond, start to enter 50cm of water to cultivate the pond. During the period, use inorganic fertilizers, inorganic fertilizers, urea, and superphosphate to topdress the same...

Embodiment 2

[0032] A method for culturing selenium-enriched sea prawns in freshwater, comprising the following steps:

[0033] (1) Preparation of selenium-enriched feed: 150-250 parts of selenium-enriched corn with a selenium content of 15-20 mg / kg and 200 parts of selenium-enriched soybeans with a selenium content of 10-15 mg / kg were washed, dried and ground respectively. Form into particles with a particle diameter of 1 mm, mix evenly, add 200 parts of traditional Chinese medicine additives, and prepare selenium-enriched feed;

[0034] (2) Shrimp pond construction: build a new shrimp pond. After 3 days of exposure to the sun, 30cm of water will enter the bottom of the pond. Quicklime will be used to sprinkle the whole pond to remove wild fish and shrimps and eliminate pathogenic microorganisms; During the period, use inorganic fertilizers such as urea and superphosphate to topdress the same amount every other day, and after 10 days of water, the color will be light yellow-green, and the...

Abstract

The invention relates to the technical field of breeding of sea food products, in particular to a method for breeding selenium-enriched sea shrimps with fresh water. The method comprises the following steps: preparing selenium-enriched feedstuff; constructing a shrimp pond; culturing young shrimps; desalting the young shrimps; carrying out breeding management; and fishing finished sea shrimps and the like. According to the selenium-enriched feedstuff and the method for breeding the sea shrimps, the selenium content of the selenium-enriched feedstuff is higher than that of selenium-containing feedstuff in markets, meanwhile, various traditional Chinese medicine ingredients with effect of resisting diseases are added in the selenium-enriched feedstuff, growth of the sea shrimps is promoted effectively, the disease resistance of the sea shrimps is improved, the survival rate of the sea shrimps is increased, the shrimp flesh quality and the selenium content of the shrimp flesh are improved, and the economic benefit is increased; and meanwhile, the feedstuff is thrown in different time periods reasonably, the quantity of the feedstuff is gradually increased, nutrition required for the sea shrimps in the growth process is supplemented in time, and therefore, nutrition and fat flesh of the sea shrimps are guaranteed.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a method for cultivating selenium-enriched sea prawns in fresh water. Background technique [0002] Shrimp is also called: red shrimp, red shrimp, and large green shrimp. It is a general term for the meat or the whole of aquatic products and marine shrimp. It is rich in nutrients. Freshwater cultured shrimp has developed rapidly in coastal cities, but traditional farming techniques There are often problems such as insufficient feeding, unbalanced nutrition, and low survival rate of sea shrimp. [0003] Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. Selenium, vi...
