Interpretive Summary: Peracetic acid (PAA) is a new disinfectant which would be better to use in aquaculture to reduce fish pathogen loads than other compounds that leave residues. PAA is environmentally friendly and degrades very rapidly to acetic acid, oxygen, and water; it does not leave toxic residues. PAA could be used in recirculation aquaculture systems (RAS) to kill bacteria that cause fish diseases at very low concentrations without harming the bacteria in the filter.

Technical Abstract: Peracetic acid (PAA) has been identified as an efficacious alternative to common disinfectants used in aquaculture settings to reduce fish pathogen loads. Compared to other aquaculture disinfectants like formalin, PAA is considered relatively environmentally friendly, given that it degrades to acetic acid, oxygen, and water when applied in an aqueous environment, and does not leave toxic residues. Additionally, PAA has been shown to be a useful therapeutant in recirculation aquaculture systems (RAS) due to its antimicrobial properties at low doses that, in turn, do not impair biofilter nitrification.
