Fredricks, K.T., Schleis, S., Erickson, R., Smerud, J., and Gaikowski, M.P., 2017, Determine the effect of 35% PEROX-AID® (hydrogen peroxide), administered to control mortality from saprolegniasis, on the nitrogen oxidation efficiency of the biofilters of in recirculating aquaculture systems (RAS) for freshwater finfish: U.S. Geological Survey data release , https://doi.org/10.5066/F7HD7TM2.

These data were collected to determine how bacterial nitrification in recirculating aquaculture systems changes when exposed to hydrogen peroxide. Hydrogen peroxide is an approved aquaculture therapeutic drug, but not yet approved for use in RAS. These data will help support data already accepted by the U.S. Food and Drug Administration (FDA) that demonstrated the effectiveness of 35% PEROX-AID® (hydrogen peroxide) to (1) control mortality in freshwater-reared finfish eggs due to saprolegniasis, (2) in freshwater-reared salmonids due to bacterial gill disease, (3) in freshwater-reared coolwater finfish and channel catfish due to external columnaris disease, (4) in freshwater-reared finfish due to saprolegniasis and (5) reduce infestation density in freshwater-reared salmonids due to Gyrodactylus sp. The use of 35% PEROX-AID® for these label claims is designated by the FDA Office of Minor Use Minor Species (MUMS). This research supports expansion of the approved label of 35% PEROX-AID® (hydrogen peroxide), a MUMS-designated drug, to control the aforementioned pathogens of freshwater finfish in RAS.
