Determine the effect of Parasite-S (formalin), administered to control mortality from saprolegniasis, on the nitrogen oxidation efficiency of the biofilters of recirculating aquaculture systems (RAS) for freshwater finfish – Laboratory Studies

This dataset includes laboratory data collected to determine the effects of formaldehyde on nitrification processes in biofilters of recirculating aquaculture systems (RAS). Data from the laboratory studies were used to inform methods used to conduct field trials in a pilot and commercial-scale RAS. Biofilter nitrification was monitored by measuring the levels of total ammonia nitrogen, nitrite, and nitrate in experimental aquaria containing a small biofilter before and after formaldehyde was applied to the test system.
