Carbon Dioxide as an Invasive Carp Behavioral Deterrent
Invasive Carp Control: Carbon Dioxide Introduction of invasive carps into public waters of the United States has resulted in a large effort to limit dispersal beyond the Mississippi River watershed. Navigational structures positioned throughout most major rivers are potential pinch-points to block further range expansion into new areas. Carbon dioxide (CO2) is being evaluated as fish deterrent to...
Developing RNA Interference to Control Zebra Mussels
We aim to develop a control tool for eliminating zebra mussels that exploits natural gene regulation mechanisms (RNA-induced gene silencing; RNAi) to be specific to zebra mussels without non-target effects. In addition to the nuisance they pose, Pimentel et al . estimated that zebra mussels cost the U.S. economy over $1 billion annually. Zebra mussels are among the International Union for...
BOR environmental DNA sampling for invasive mussels at USGS gages
As part of an ongoing project funded by the Bureau of Reclamation and lead by the Idaho Water Sciences Center (IDWSC) and Northern Rocky Mountain Research Center (NOROCK), the Upper Midwest Environmental Sciences Center (UMESC) will analyze environmental DNA samples collected at gage stations directly downstream of multiple reservoirs throughout the Columbia River Basin. The goal of this project...
Assessment of newly developed acoustic stimuli for manipulating movement of bigheaded carps
Bigheaded carps, like other cyprinids, have specialized structures known as Weberian ossicles that increase their hearing range and sensitivity. Recent results from controlled laboratory studies have indicated that playback of a recording of an outboard boat motor was effective at altering silver and bighead carp behavior.
Work with U.S. Fish & Wildlife Service – Reed Canary Grass
Impact of UMESC Science To generate decision-making information needed for refuge managers on how to treat reed canary grass in order to maintain or restore target communities and the wildlife they support.
Increasing Efficiency and Throughput of eDNA
The results from this study will provide protocols for the collection, processing and analysis of environmental deoxyribonucleic acids (eDNA) samples for monitoring aquatic invasive species like Asian carp. These protocols have the potential to be used by fishery management agencies to monitor aquatic invasive species throughout the United States.
Develop Experimental Use Permits, Datasets and Develop Registration Plans for Sea Lamprey Pheromones in Compliance with United States and Canadian Biopesticide Regulations
The result of this technical assistance is critical to developing a lamprey pheromone as a tool to control lamprey populations in the Great Lakes. If lamprey populations are left uncontrolled, the effects lamprey would have on the fishery industry in the Great Lakes would be devastating.
Improving the Accuracy and Precision of Predictions of TFM-niclosamide Concentrations for Treatment of Sea Lamprey Spawning Tributaries
The results of this research may lead to a more efficient use of the lampricides used to control lamprey populations in the Great Lakes. If lamprey populations are left uncontrolled, the effects on commercial and sport fisheries in the Great Lakes would be devastating. The treatment of sea lamprey spawning tributaries with mixtures of the piscicides 3-trifluoromethyl-4-nitrophenol (TFM) and 2'5'...
Register New Lampricide Active Ingredients and End-use Formulations and Maintain Registered Products in Compliance with United States and Canadian Pesticide Regulations
The USGS Upper Midwest Environmental Sciences Center (UMESC) provides regulatory affairs assistance to the Great Lakes Fishery Commission (GLFC), U.S. Fish and Wildlife Service (FWS), Department of Fisheries and Oceans Canada (DFO), state and private partners in matters regarding numerous registrations of the lampricides TFM and niclosamide in the U.S. and Canada. The result of this technical...
Residue Levels of the Lampricides TFM and Niclosamide in Moribund Sea Lamprey Larvae Following Exposures to TFM and a TFM/1% Niclosamide Combination
Concerns regarding the exposure of wildlife to TFM and niclosamide that would result from the consumption of sea lamprey (Petromyzon marinus) larvae exposed to these chemicals has prompted a need to investigate uptake of these chemicals in larval lampreys. A study to address concerns regarding the exposure of the endangered common term during the treatment of the St. Marys River was completed in...
Forensic Markers of Lampricide Toxicity & Mortality in Non-Target Fishes
The pesticides 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide selectively target larval sea lampreys (Petromyzon marinus) because they have a much lower capacity to detoxify these lampricides by forming glucuronide conjugates compared to typical non-target fishes. Glucuronidation makes lampricides more water soluble and easier to excrete (Lech and Statham 1975; Kane et al. 1994). However...
Sea lamprey (Petromyzon marinus) density estimates using environmental DNA surveillance
Sea lampreys are a species that invaded the Great Lakes presumably following the improvements made to the Welland Canal in 1920. First reported in Lake Erie in 1921, sea lampreys subsequently spread rapidly to the upper Great Lakes and had an established spawning population in all of the upper Great Lakes by 1947 (Applegate 1950). Following their introduction, sea lamprey devastated the commercial...
