Aquaculture sector, primarily those of Limnoculture (Freshwater fishes) and Vannamei culture (Freshwater shrimps) extensively use disinfectants in their farms for bio-security in addition to routine cleaning processes. They’re utilized to inactivate microbes that were potential on gear surface, tanks, ponds and clothes. They are also utilised to disinfect gametes ova. Disinfectants are essential during decontamination operations following the outbreak of notifiable diseases like Infectious Salmon Anaemia (ISA), Spring Viraemia of Carp (SVC) or Viral Haemorrhagic Septicaemia (VHS) etc.. Regardless of widespread and effective use of disinfectants, several contributing factors greatly determine the criterion for their choice and application.
Disinfectants mostly contain blend of stabilizers and compounds that could have compositions or broad spectrum program of chemicals for target pathogens. Chemical disinfection of water and equipments is a task due in natural waters as well as to impacts of the reagents themselves and the after effects, both in the aquaculture system. The requirement gradually shifted nontoxic cost disinfectants; those who pathogens can’t adapt to or develop resistance. The best choice for this is using Oxidizing Disinfectants. These are chemicals that indifferently oxidize organic matter in water. Thus their mode of disinfection is oxidation of cell membrane pathogen cell wall and cytoplasm. As an efficient aquaculture disinfectant, Peroxides, particularly in the form of Silver Hydrogen Peroxide has found widespread application of all oxidizing agents’ kinds.
The disinfectant properties of H2O2 applied and have been popularly discussed in recent years. Synergized with nano-silver, the stabilized AgH2O2 is an excellent disinfectant that is active over a wide spectrum of microscopic in addition to macroscopic pathogens. Its flexibility as a pathogen cleaner and dirt remover makes it an ideal choice for disinfecting water tanks, little ponds and incubation chambers. It is most suitable for application in tanks and ponds as well as gear disinfection with or without water. Its toxicity towards greater aquatic fauna makes it perfect through spread of diseases within the aquarium systems for treatment.
Silver stabilized H2O2 at even low concentrations have disinfecting properties from a wide array of pathogens compared to identical concentrations of disinfectants. Additionally, H2O2 has no toxicity towards cultivated fish and fish eggs. It quickly degrades releasing oxygen that kills the germs leaving no residue. It is non corrosive to tank materials and price friendly. Moreover, Silver itself has by attacking bacterial DNA material certain properties.
Required Property How AgH2O2 tallies
