Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute pesticide toxicity tests
Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.
Crayfish morphometric measurements, burrow attributes and occupancy in response to physical burrow barriers
Data were collected in association with the application of two physical barrier treatments, bentonite clay (a sealing agent) and expanding foam (an insulation sealant), in natural pond-burrows to suppress or kill the invasive red swamp crayfish (Procambarus clarkii). Data include burrow diameter and depth, crayfish sex and size, and determination of the treatment reaching the burrow chamber.
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...
In order to estimate the costs of chemical control of non-indigenous crayfish versus the cost of manual inspection of fish hatchery shipments a cost analysis was performed. The data includes ranking the likelihood of missing non-indigenous crayfish and effects on fish of handling during manual searches and the effects on fish during chemical exposure. The data also includes estimates of the time, staff, and salary requirements and cost of materials for each approach.
Water quality and atmospheric carbon dioxide data for field application of carbon dioxide during summer 2018 as a behavioral control method for invasive red swamp crayfish (Procambarus clarkii) in southeastern Michigan water retention ponds.
This study evaluated carbon dioxide (CO2) injected into water as a possible behavioral stimulant to enhance capture and removal of invasive red swamp crayfish (RSC, Procambarus clarkii Girard, 1852) from a retention pond in southeastern Michigan. Objectives of this study were to (1) determine if target CO2 concentrations were attainable within the infested pond, and (2) determine if CO2 treatment was effective to push RSC towards shorelines or onto dry land where they could be collected and removed. Carbon dioxide was applied directly into one treatment pond (~2,500 m3) in Novi, MI. Two nearby ponds in Livonia, MI were used as untreated control ponds. Crayfish removal efficiency was evaluated in all ponds using...
