"The study of Nano silver in the usage on aquafarm" byEstherteam
為了解決餌料生物攜帶病原菌的困擾，本研究以奈米銀產品針對植物性與動物性餌料生物進行評估，結果發現：奈米銀會影響植物性餌料生物如等鞭金藻，海洋擬球藻與周氏扁藻的活性，雖然可以降低所攜帶病原菌的總量，但由於其嚴重影響餌料生物活性，故不建議使用。而在對動物性餌料生物的研究中發現，以奈米銀16 ppb處理 15 分鐘不但不會影響輪蟲，豐年蝦與橈足類的活性，而且可以有效降低病原菌感染的風險。
This study aimed at the company new process of new nano silver products, used in aquaculture in the process of disinfection with the method and technology of bacteriostasis, bacteriostatic ability and the effect of specific pathogen bait biological disinfection, water treatment and other common risk assessment in the aquaculture industry, establish future products for the applied mode of the aquaculture industry in order to reduce the risk of drug abuse, reducing food security threat.This study the current research found that:
New type of nano silver to dissolve, v. enteritis vibrio, vickers vibrio, Edwardian, heavy water gas, bacterium streptococcus, streptococcus disease and so on seven strains common aquatic organisms have significant inhibition, no matter in nano silver added in water or made from nonwoven filter material can effectively restrain seven strains of pathogenic bacteria in aquaculture water quantity, reduce the risk of disease outbreaks.And nano silver will not impact on water quality, breeding biology pressing.
Nano silver products in addition to water sterilization, can also be used for figured eggs to wash process, effectively reduce the pathogen infection sex disease, increase the hatching rate and fish production.This project through small-scale trial production and the grouper seedling cultivation in the process of tutoring companies found that using nanometer silver products can improve three inches seedling yield was 12%, and the future will be able to effectively solve the difficulties of inadequate grouper seedling production.
In order to solve the bait biological carrying pathogenic bacteria, this study nano silver products in view of the plant and animal bait biological evaluation, it is found that nano silver affects plant bait organisms such as whip chrysophyte, ocean to found and zhou bian, the activity of algal although can reduce the amount of carried by pathogenic bacteria, but due to its serious influence bait biological activity, so it is not recommended.In the study of animal bait creature found that nano silver 16 parts per treatment not only will not affect the rotifers, 15 minutes brine shrimp and the activity of copepods, and can effectively reduce the risk of pathogen infection.
The company research and development of new nanoscale silver products compared with the prototype nano silver products in antibacterial ability and other related indicators and there was no significant difference, the new product stability is better than that of the prototype, will help to improve the competitiveness of future products.And the results of this study show that nanoscale silver can effectively reduce the risk of pathogenic bacteria breeding, also as animal bait biological disinfection in order to reduce the risk of infection, does not affect the water quality at the same time.Future once a large number of popularization and application in industry, which can effectively solve the disease and breeding management of aquaculture industry, improve industry profits, strengthen the international competitiveness of the aquaculture industry in China.
