A method for degrading heavy metals in the process of holding aquatic animals

Abstract

The invention provides a method for degrading heavy metals in a temporary rearing process of aquatic livestock. In the temporary rearing process of the aquatic livestock, a compound vitamin for fish or EDTA (Ethylene Diamine Tetraacetic Acid) or a mixture of the compound vitamin for the fish and EDTA is added into raising feed; the adding amount of the compound vitamin in the raising feed is 4-10g / Kg and the adding amount of EDTA is 1.0-3.2g / Kg. The method is simple to operate and low in production cost. In the use process, the compound vitamin for the fish and ethylene diamine tetraacetic acid are added into the feed to prepare the efficient and safe aquatic feed and can also be added independently in the raising process. The method provided by the invention can be used for effectively degrading the heavy metals in aquatic products, reducing the toxin to the aquatic livestock and a human body by the heavy metals and degrading the residue of the heavy metals in the aquatic products; the safety of the aquatic products is guaranteed.

Description

technical field [0001] The invention relates to a method for temporarily raising aquatic animals, in particular to a method for degrading heavy metals during the temporary raising of aquatic animals. Background technique [0002] Aquatic products are one of the important sources of animal protein intake for human beings. They have the characteristics of high protein, low fat, and good nutritional balance, making their status on the dining table continuously improved. my country is a big country in the production and consumption of aquatic products. plays an important role in the national economy. With the popularization of high-density intensive farming technology, the aquaculture industry has developed rapidly. The rapid development of fishery has driven and promoted the rapid development of fishery economy and foreign exchange earning in various places, bringing huge economic benefits. However, the rapid development of modern industry and the widespread use of a large num...

Problems solved by technology

However, heavy metals cannot be degraded in the environment. Once they enter the breeding environment, they will become enriched and amplified in aquatic products through the food chain, posing a serious threat to food safety.
