The majority of commercially available disinfectants are mixtures of chemicals and stabilizers, which can either be broadly effective or selectively composed to kill only certain types of pathogens. Due to the long-term effects and environmental impacts of the reagents themselves, chemical disinfection of water and equipment is a crucial task in the aquaculture system and in natural waters. Over time, broad-spectrum, biodegradable, nontoxic, and economically viable disinfectants became necessary; ideally, these would be so effective that pathogens would never develop resistance. In this case, oxidizing disinfectants are the best option. These chemicals oxidize organic matter in water without bias. Therefore, they kill germs by oxidizing their cell membranes, cell walls, and cytoplasm. Silver hydrogen peroxide, in particular, has proven to be an effective oxidizing agent for use in aquaculture.
Disinfectants are used extensively in the aquaculture sector, especially in Limnoculture (Freshwater fishes) and Vannamei culture (Freshwater shrimps) farms for bio-security and routine cleaning processes. To prevent the spread of disease, they are applied to the surfaces of tanks, ponds, and garments. They are also used to kill bacteria on gametes, especially ova. After an outbreak of a reportable disease, such as Infectious Salmon Anaemia (ISA), Spring Viraemia of Carp (SVC), or Viral Haemorrhagic Septicaemia (VHS), etc., decontamination operations will require the use of disinfectants. Despite disinfectants’ widespread and effective use, several factors greatly determine the criteria for their choice and application.
H2O2’s disinfectant abilities have received a lot of attention and been used in practice in recent years. Thanks to nano-synergistic silver’s effect, stabilized AgH2O2 is an effective disinfectant against a wide range of microbes and larger organisms. Disinfecting water storage containers, little ponds, and incubation chambers is a breeze with this multipurpose cleaner. It works well in water or dry conditions, making it ideal for use in raceway ponds and tanks. It’s great for treating diseases that spread through aquarium systems because it’s not toxic to the higher aquatic fauna kept there.
When compared to other commercial disinfectants of the same concentration, silver-stabilized hydrogen peroxide has significantly higher disinfecting properties at low concentrations against a wide range of pathogens. It has also been found that H2O2 is not toxic to fish eggs or to most types of farmed fish. It degrades quickly, releasing nascent oxygen that kills the pathogens while leaving no toxic residue in the environment. It won’t eat away at your tank and it’s cheap! Furthermore, silver itself has bactericidal properties, specifically targeting bacterial DNA.
