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...

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'...

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.
