Use of terrestrial plant-based bait and algae attractant to improve capture efficiency of Grass Carp in Lake Erie tributaries
A team of USGS scientists is currently working with the MDNR, ODNR, USFWS, and academic institutions to evaluate the use of grass carp baits and attractants as a tool for resource managers. The science team aims to integrate the use of baits and attractants to increase aggregation of grass carp near targeted capture sites to enhance the multi-jurisdictional removal program associated with the Lake...
Evaluation of selective Grass Carp bait
No current technology can specifically target Grass Carp Ctenopharyngodon idella for control within aquatic ecosystems. Other than TFM (3-trifluoromethyl-4-nitrophenol) for Sea Lamprey Petromyzon marinus control, available control chemicals used in aquatic invasive species management programs are non‐selective and typically applied throughout the entire water column, resulting in equal exposure of...
Hydroacoustic detection of dreissenid mussels and their habitat: an innovative way to detect dreissenid infestations and model preferred habitat for future colonization
The proposed project will explore the technology of hydroacoustics to detect dreissenid mussels and analyze habitat variables to model preferred future habitat locations to help control the spread of invasive dreissenid mussels.
USGS Coordinated Burmese Python Research Strategy for South Florida (FY21 – FY27)
Wetland and Aquatic Research Center and Fort Collins Science Center are coordinating a long-term, landscape-scale Burmese python research strategy for South Florida.
Using Scout Burmese Pythons and Detector Dogs to Protect Endangered Species in the Florida Keys
WARC researchers are addressing an urgent need to identify specific habitat use of pythons on Key Largo, FL.
Understanding Greater Everglades Mammal Communities within and adjacent to the Arthur R. Marshall Loxahatchee National Wildlife Refuge
WARC Researchers are using a variety of methods to assess mammal communities across the Greater Everglades.
Virtual Fish Slam - March 2021
In March 2021, USGS researchers and partners conducted the first-ever Virtual Fish Slam. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native freshwater fishes.
Early Detection and Rapid Response: Removal of Newly Introduced Non-native Marine Fishes to Prevent Invasions
USGS WARC works with partners on early detection and rapid response (ED/RR) efforts, rapidly removing newly introduced non-native marine fishes from Florida’s coastal waters to prevent invasions.
Biology, Impacts and Control of Invasive Reptiles in the Pacific
Research on Guam has led to development and validation of numerous effective control tools, including the advancement of reptile control to support native species recovery.
Monitoring and Removal of Invasive Cuban Treefrogs (Osteopilus septentrionalis) on the Gulf Coast
WARC researchers are performing visual encounter surveys and passively capturing Cuban treefrogs to remove as many of the invasive anurans as possible.
Development of Sampling Protocols and Diagnostic Tools for Assessment of Freshwater Mussel Health
Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems The role of disease in freshwater mussel declines has been largely ignored due to the lack of appropriate diagnostic tools. Furthermore, health assessment of mussels in conjunction with restoration and propagation has not been considered during stocking and augmentation activities. This project will develop standard...
Development of Selective Control Tools
Management Tools for Dreissenid Mussels Currently, dreissenid mussel populations are spreading and becoming a growing problem in many aquatic systems, making it important to find management techniques that are selective for the invasive mussel populations while leaving the native populations intact. Control technology for dreissenids in open water currently relies on a limited number of...
