Evaluation of dissolved carbon dioxide (CO2) as a non-physical deterrent to invasive Red Swamp Crayfish (Procambarus clarkii) and Rusty Crayfish (Faxonius rusticus): Data

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 and time of the first and last shuttle after CO2 injection began, and the total times spent in the injected and non-injected chambers. Loss of equilibrium (LOE) data were collected on 20180117 through 20180119 (LOEStats.csv). Crayfish were placed in a bucket with water and CO2 was injected into the bucket until the crayfish lost equilibrium. The concentration of CO2 and time until LOE occurred was recorded along with other behaviors induced by the elevated CO2 concentration. Red swamp crayfish emergence data was collected on 20180221 through 20180227 (Incline.csv). One side of the choice chamber used in the behavior/shuttle trials was isolated and an incline ramp was placed on the tank. CO2 was then injected into the tank and the behavior of the crayfish was recorded. Behavior data was recorded as in the tank, on the incline, or out of the water.
