This data set is associated with an administrative report submitted to the U.S. Food and Drug Administration Center for Veterinary Medicine (CVM). The project goal was to determine the effects of hydrogen peroxide on the microflora of recirculating aquaculture systems (RAS). There are few aquaculture drugs approved for use in RAS and the CVM will evaluate findings from the study to determine if hydrogen peroxide would be safe to use in RAS.
Carbon dioxide (CO2) is under consideration as a chemical fish deterrent at pinch points in rivers (e.g., inside locks) to reduce unwanted fish passage. This study evaluated the behavioral responses of invasive round goby (Neogobius melanostomus) to dissolved CO2 in laboratory tanks. The goal of this project was to quantify CO2 concentrations that modify round goby behavior. More specifically, avoidance behavior (voluntary response) and loss of equilibrium (involuntary response) were quantified across 5, 15, and 25°C water temperatures. These data can be used to inform future field testing of CO2 as an invasive fish deterrent. Spreadsheets include data that were used to evaluate the efficacy of carbon dioxide (CO2)...

This dataset includes data collected to determine the effects of formaldehyde on nitrification processes in biofilters of recirculating aquaculture systems (RAS) from two field trials. 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.

This dataset includes laboratory data collected to determine the effects of hydrogen peroxide 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 pilot- and commercial-scale RAS. Biofilter nitrification was monitored by measuring the levels of total ammonia-nitrogen, nitrite-nitrogen, and nitrate-nitrogen in experimental aquaria containing a small biofilter before and after hydrogen peroxide was applied to the test system. There are 4 excel workbooks associated with this data set: RASHP Range finding Trial.csv, RASHP Definitive Trial.csv, Hydrogen Peroxide Lab Studies.csv, and DO after HP...
