Deployment and Evaluation of an Underwater Acoustic Deterrent System at Lock and Dam 19
Previous studies and experience have demonstrated that some locks and dams operate as bottlenecks or pinch points for invasive carp populations and range expansion because of unique hydraulic conditions and operations at these dams. As compared to dams without these unique conditions, pinch-point dams restrict upstream fish passage to the lock chamber and result in limited (but not zero) upstream...
Detecting seasonal movements and spawning of bigheaded carp using environmental DNA (eDNA)
Silver carp ( Hypophthalmichthys molirix ) and bighead carp ( H. nobilis ), commonly call bigheaded carp, are native to portions of Asia and were introduced to North America in aquaculture farms and sewage treatment ponds to control algae and plant growth. Bigheaded carp escaped from their intended locations and have an adverse effect on the ecosystem functions and the economic value of the...
Modeling to inform bighead and silver carp management
Bighead carp ( Hypophthalmichthys nobilis ) and silver carp ( Hypophthalmichthys molitrix ) are invasive carp species within the Mississippi River basin. In the early-1970s these species escaped from ponds where people introduced them to control algae (ICRCC). Invasive carp cause ecological and economic damage by outcompeting native species and disrupting native food webs. Stopping the spread of...
Laboratory evaluation of bait preference for Grass Carp
Michigan and Ohio Department of Natural Resources along with the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) and USGS Upper Midwest Environmental Science Center (UMESC) are planning field studies to attract Grass Carp using formulated baits and algae attractants. These baits are intended to increase the density of Grass Carp in specified areas for capture and...
Method development for intestinal cannulation to dose filter feeding fishes
Currently, the only U.S. Environmental Protection Agency (USEPA) registered pesticide for resource managers to control populations of Invasive Carp (e.g., Bighead Carp, Hypophthalmichthys nobilis ) are rotenone (Prenfish Fish Toxicant; EPA Reg. No. 89459-85) and Carbon Dioxide – Carp (EPA Reg. No. 6704-95). An alternative to rotenone and Carbon Dioxide – Carp, antimycin-A (ANT-A), is desired by...
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...
Assessment and methods development of dyed feeds for the evaluation of toxic fish bait consumption
Recently there has been an increased removal effort of adult Grass Carp Ctenopharyngodon idella from the Lake Erie Basin through traditional capture methods (Herbst et al. 2021). Use of chemical control tools such as a general or ingestible pesticide to support this removal effort has been identified as a potential management option (Robinson et al. 2021).
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.
Database and web application for invasive carp catch data (Illinois River Catch Database)
Four types of invasive carp are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional Coordinating Committee (ACRCC) implements...
Database and web application for invasive carp telemetry data (FishTracks)
Four types of invasive carp fish species, are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade. To prevent the spread of invasive carp into the Great Lakes, the multi-agency Asian Carp Regional Coordinating Committee (ACRCC)...
Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems
Native freshwater mussels play a critical role in aquatic environments and are considered “ecosystem engineers” and indicators of water quality by constantly filtering water. Populations of native freshwater mussels have declined in recent years, and this decline has been attributed to factors such as habitat degradation, pollution, and invasive species, among others. The importance of these...
