Acute Toxicity of Carbon Dioxide to Juvenile Red Swamp Crayfish (Procambarus clarkii) Acute Toxicity of Carbon Dioxide to Juvenile Red Swamp Crayfish (Procambarus clarkii)
This study evaluated the use of dissolved carbon dioxide as a control method for juvenile red swamp crayfish (Procambarus clarkii). Four concentrations of CO2 and a control were administered to 18 test tanks over a 96-hour period. Red swamp crayfish were observed for behavioral changes during the exposure and were assessed for mortality 24 hours post treatment. Datasets include daily...
Investigation of Red Swamp Crayfish (Procambarus clarkii) Burrowing Behavior Investigation of Red Swamp Crayfish (Procambarus clarkii) Burrowing Behavior
This study used artificial burrowing chambers to investigate the effects of groundwater drainage rates and soil type on burrow initiation and morphology of red swamp crayfish (Procambarus clarkii). The relationship between caloric density of crayfish and burrowing was also examined. The objectives of this study were to (1) determine the effect of ground water drainage rates on burrowing...
Evaluation of multiple sedation techniques on invasive carps and native fish species in summer 2023 and 2024 Evaluation of multiple sedation techniques on invasive carps and native fish species in summer 2023 and 2024
This study evaluated three sedation methods to determine their efficacy for use during telemetry tagging. Five fish species (bighead carp, grass carp, bigmouth buffalo, American paddlefish, and lake sturgeon) were sedated using eugenol (AQUI-S® 20E), dissolved carbon dioxide, and electroanesthesia to determine sedation induction times. After sedation, half of the fish from each treatment...
Anesthetic properties of carbon dioxide on native and invasive fishes Anesthetic properties of carbon dioxide on native and invasive fishes
This study evaluated the anesthetic properties of dissolved carbon dioxide on six fish species to determine its efficacy for use in sedating wild caught fish for surgeries. Phase I of this study aimed to inform induction time, recovery time, and short-term survival of fish using five different concentrations of carbon dioxide at one water temperature. Phase II determined the induction...
Acute Toxicity of Carbon Dioxide to Crayfish Acute Toxicity of Carbon Dioxide to Crayfish
This study evaluated the use of dissolved carbon dioxide as a control method for invasive crayfish. Five concentrations of CO2 were administered to twenty-four test tanks at a water temperature of 5°C. Initially, Red Swamp Crayfish (RSC; Procambarus clarkii) were intended to be the test species used in the study. However, problems with obtaining a healthy population of RSC occurred, so...
Acoustic Telemetry Evaluation of Invasive Red Swamp Crayfish (Procambarus clarkii) Behavior in Southern Michigan (Summer 2021) Acoustic Telemetry Evaluation of Invasive Red Swamp Crayfish (Procambarus clarkii) Behavior in Southern Michigan (Summer 2021)
This study deployed acoustic telemetry into a red swamp crayfish-infested water retention pond (1.0 ac) near Novi, Michigan to document the movements and behavior of telemetered red swamp crayfish (Procambarus clarkii). Telemetry was setup in the pond for approximately 3 months. Spreadsheets include telemetry data with position estimates for individual crayfish.
Acoustic Telemetry Evaluation of Invasive Carp in Kaukauna, Wisconsin (Summer 2019) Acoustic Telemetry Evaluation of Invasive Carp in Kaukauna, Wisconsin (Summer 2019)
This study deployed acoustic telemetry at the Fox River Navigational System Authority (FRNSA) in lock #2 and the upstream and downstream pools in Kaukauna, WI to document movements and behavior of telemetered fish species in response to injection of carbon dioxide. Telemetry equipment was setup in the test area for approximately 2 months during the summer of 2019. CSV metadata includes...
Treatment of Aeromonas salmonicida in Lake Herring (Coregonus artedi) Using Medicated Feeds Treatment of Aeromonas salmonicida in Lake Herring (Coregonus artedi) Using Medicated Feeds
This study evaluated the use of medicated feeds to treat furunculosis infections caused by the bacterium Aeromonas salmonicida in lake herring (Coregonus artedi, Lesueur, 1818). The objectives of this two-phase study were to (1) determine if Coregonus artedi could be adequately and consistently infected with A. salmonicida by the methods of bath immersion or intraperitoneal (IP)...
Efficacy of florfenicol and oxytetracycline administered in feed to control cisco mortality associated with Aeromonas salmonicida infections Efficacy of florfenicol and oxytetracycline administered in feed to control cisco mortality associated with Aeromonas salmonicida infections
Two medications (one with florfenicol and one with oxytetracycline) that are approved in the United States to control mortality due to furunculosis associated with Aeromonas salmonicida were assessed to determine their efficacy in medicated feeds to treat A. salmonicida-infected Cisco (also known as Lake Herring) Coregonus artedi. Cisco were subjected to static infection baths containing...
