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. However, if lampricide uptake overwhelms a fish's detoxification capacity, non-target mortality can result. Non-target mortality...

Evaluation of dissolved carbon dioxide (CO2) as a non-physical deterrent to invasive Red Swamp Crayfish (Procambarus clarkii) and Rusty Crayfish (Faxonius rusticus)

Red swamp crayfish (Procambarus clarkii) and Rusty crayfish (Faxonius rusticus) are invasive crayfish species in nearly all Great Lakes states (https://nas.er.usgs.gov/viewer/omap.aspx?SpeciesID=217). Both species are a concern in Michigan because they can displace native crayfish populations, their feeding behavior reduces habitat for amphibians, juvenile fish, invertebrates, and waterfowl. They...

Avoidance behavior of larval sea lampreys in response to Bayluscide® as an evaluation of the utility of a Bayluscide® bar formulation in sea lamprey control operations

This study will be conducted to provide information on the avoidance behavior of larval sea lampreys in response to the lampricides 3-trifluoromethyl-4-nitrophenol (TFM) and 2’,5-dichloro-4’-nitrosalicylanilide (niclosamide). The data generated will be used to evaluate the feasibility of developing a new lampricide formulation (Bayluscide® Solid Bar) for use in the Great Lakes Fishery Commission’s...

Evaluation of the toxicity of niclosamide to two fresh water mussel species and larval sea lampreys (Petromyzon marinus) when exposed to granular Bayluscide

Niclosamide (5-chloro-N-[2-chloro-4-nitrophenyl]-2-hydroxybenzamide; NIC) is the active ingredient in the 3.2% granular formulation of Bayluscide® (gB). is applied to assess populations of Sea Lamprey (Petromyzon marinus) larva that are too deep to electro fish or remove larva in habitats and too large to treat with liquid formulations of lampricides in a cost effective manner. Concerns regarding...

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'...

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...

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...

Dissipation of Niclosamide Downstream from Granular Bayer Application Plots in Lotic Environments

Niclosamide (2-amino ethanol salt of 5-chloro-N-[2-chloro-4-nitrophenyl]-2-hydroxybenzamide, NIC) is the active ingredient in the lampricide Bayluscide®. Bayluscide® 70% wettable powder is typically used in combination with TFM to reduce the amount of TFM required for an effective treatment.
