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 data was collected to determine responses of red swamp crayfish and rusty crayfish to CO2-enriched water to determine the utility of CO2 as a crayfish control tool. Avoidance tests, emergence tests, and loss of equilibrium (LOE) tests were performed to determine crayfish behavior in CO2-enriched water. Avoidance data (TimeinChamber2.csv, Crossings.csv, FirstLastShuttle.csv, AvoidanceLengthsandWeights.csv) were collected on 20171220 through 20180214. CO2 was injected in one side of a choice chamber under light or dark conditions and 10oC or 24oC water temperature. Shuttle movements were recorded and used to determine the number of crossings from the CO2 injected side to the non-injected side, the CO2 concentration...
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...
Spreadsheets include data that was used to evaluate the efficacy of carbon dioxide (CO2) deterrence at different temperatures in invasive carps. There are 8 csv files and 2 folders containing text documents associated with this study.

Resource agencies are searching for effective methods to prevent the spread of invasive Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (Hypophthalmichthys nobilis), hereafter bigheaded carps, from the Mississippi River basin into the Laurentian Great Lakes. Elevating carbon dioxide (CO2) concentrations in water within locks and other pinch points is an approach being considered to reduce invasive fish passage. Laboratory studies have shown that bigheaded carps strongly avoid areas of elevated CO2 (Kates et al. 2012; Dennis et al. 2015). Similarly, telemetry studies found that CO2 can be used to exclude bigheaded carps from certain locations (Donaldson et al. 2016) and reduce upstream movement (Cupp et...
