Technical Abstract: This presentation will discuss collaborative efforts on research to evaluate the usefulness of peracetic acid (PAA) as a therapeutant in aquaculture. Research has been underway since 2009 with a scientist from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (Berlin, Germany). There are few legal compounds in Europe for use in aquaculture, and there is not much information available for PAA. As for the U.S., this could be another tool for the therapeutant arsenal that current drug researchers are pursuing. We have studied the effectiveness of PAA as a treatment against freshwater fish pathogens like Ichthyophthirius multifiliis, Flavobacterium columnare and Saprolegnia parasitica; in recent studies with saprolegniasis on catfish eggs, PAA was demonstrated to be an effective treatment at low concentrations. Results suggest PAA could be used for additional disease treatments in freshwater aquaculture; however, more information is needed to evaluate its usefulness on various diseases, species and culture settings. For the safe use of PAA, toxicity data for different fish species and life stages, as well as data for application at different chemico-physical water conditions, are essential. There is only one published study concerning the acute toxicity of PAA; this was done on juvenile walleye. According to a 2001 European report, there are unpublished LC50 values reported for rainbow trout, bluegill, and zebrafish; these studies were initiated by chemical companies to provide data for their registration as disinfectants.
