Media reports to the condition that adds piscine float spirit may exist in alluding to carry a process in aquatic product breed aquatics.
What is piscine float spirit? May spirit of float of aquatic product use fish exist what kind of risk?
The following, we will be unscrambled for your one by one.
Piscine float spirit is a kind of chemistry adds oxygen agent
Have in the breed aquatics of aquatic product and current link use
Piscine float clever common says " solid hydrogen peroxide solution " , its commodity name still has bead bead oxygen, big oxygen and solid to add oxygen piece etc. The bases of this product is sodium carbonate crossing oxygen commonly, be in the majority with tablet form, also have a few sell with dust form. In putting water on piscine float spirit hind, meeting hydrolyze is sodium carbonate and hydrogen peroxide solution, at this moment sodium carbonate is worth the PH that raises water, basic requirement issues hydrogen peroxide solution to release oxygen more easily, rise to improve the result of water system dissolved oxygen thereby.
The action of piscine float spirit is lash-up adds oxygen commonly, when consecutive cloudy day or when illumination is intense, can learn to add oxygen agent to control the balance with water microbial system and improvement through joining this apperception water quality. In carriage process of live body aquatic product, spirit of use fish float can be fish, shrimp, crab to wait to offer its quickly to breathe place to need, enough oxygen portion, this prolonged their life not only, because anoxic and dispirited fish shrimp became active,still can make.
Piscine float decomposes child cleverly to accord with regulation of national relative standard
Piscine float is clever kind of product that add oxygen is current still do not have relevant state level, and because do not have the function that treats piscine disease, tell on firm sense also cannot be treated as fishing medicine. Nevertheless, basically decompose child to cross oxidation hydrogen to look from its, accord with regulation of national relative standard.
Our country Ministry of Agriculture the 235th announcement " drug of the animal in animal sex food is highest rudimental set limit to " in regulation, cross oxidation hydrogen to belong to " animal sex food allows to use, but the remedy that does not need to make rudimental set limit to " ; Our country " additive agent for food of level of food safety state uses a level " (GB 2760, 2014) in regulation, cross oxidation hydrogen to belong to " can use in process of treatment of of all kinds food, incomplete allowance does not need definitive processing aid " .
The safe risk that spirit of float of aquatic product use fish brings is limited
Public opinion thinks, think piscine float spirit basically is put in the safe risk of two respects.
It is piscine float spirit oxidation hydrogen and sodium carbonate pass in what generation decomposes in water system, the part may be expressed to absorb by piscine body or one is pass branchial enter muscle inside, put in hidden trouble. Actually, these two kinds of material pledge to the product of fish quantity and its security do not have negative effect commonly, also be occupied without any experimental testimony at present and spirit of demonstrative fish float meets reason to cause a harm to human body.
2 it is to think piscine float spirit serves as chemical, contain the heavy metal such as lead, arsenic possibly among them, put in hidden trouble. Individual and illegal pedlar may use the chemical industry that does not accord with a requirement to had tasted oxygen sodium carbonate to replace fishery to use piscine float spirit, really possible presence introduces the venture of the harmful composition such as heavy metal below this kind of circumstance.
Nevertheless, fishing pond area is in commonly 10, 200 mus differ, water system volume is large, want to achieve complete Chi Changxiao to add the effect of oxygen, the mechanical method that the cost far outclass that clever apperception of use fish float learns to add oxygen agent to add oxygen uses generally adds oxygen, the use time with piscine normally so clever float short, dosage is opposite very small also. The use time that clever apperception of float of the fish in carrying current process learns to add oxygen agent also is compared commonly short. Because heavy metal needs proper time in the save up inside piscine body, the risk that because use piscine float spirit,brings heavy metal remain on the whole is not high.

| Expert proposal |
One) advance piscine float spirit kind piscatorial investment tastes relevant code of the standard make edit the job.
Inferior fishery investment is tasted give piscatorial production and piscatorial product to bring safe risk likely. The function that because chemistry adds oxygen agent, water quality to reform the fishery such as the agent is thrown,tastes hard classify, home has not form good administrative mechanism. Standard of the national level that suggests to make phasing answer, industry, use current requirement to wait, normative industry grows, ensure food safety, raise consumer to taste quality and safe degree of belief to aquatic product.
2) clever to piscine float kind the product begins a risk to monitor.
The sodium carbonate crossing oxygen that with industrial level raw material production comes out replaces the piscine float spirit that tastes as piscatorial investment attribute illegal action, the likelihood brings particular risk hidden trouble. The proposal is begun in the light of this kind of product monitor, stimulative product pledges the quantity promotes.
3) consumer need not worry too to piscine float spirit.
The safe risk that uses piscine float clever place to bring in the breed aquatics of aquatic product and current process is limited, consumer need not worry too, the attention buys aquatic product through normal channel can.
