Data and Code Release:Technical Assistance Bioassay to Compare Sea Lamprey and Logperch Sensitivity to TFM
Data and code release to evaluate a continuous-flow streamside toxicity test that was conducted with common logperch (Percina caprodes) and larval sea lamprey (Petromyzon marinus) to evaluate the risk posed by 4-nitro-3-(trifluoromethyl)phenol (TFM) sea lamprey control stream treatments to logperch. Logperch are a host to the parasitic glochidia life stage of the federally endangered snuffbox muss
Data and Code Release: Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed
Data to evaluate the Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed. The toxicity of the lampricides TFM and TFM/1% Niclosamide to numerous non-target fishes of concern in the Great Lakes has been presented in previous studies. However, not many toxicity studies have been reported for Finger Lakes and Lake Champlain species of concern including: the
Data and code release—Comparative toxicity of emulsifiable concentrate and suspension concentrate formulations of 2′,5-dichloro-4′-nitrosalicylanilide ethanolamine salt
Bayluscide, the 2-aminoethanol salt of niclosamide (2′, 5-dichloro-4′-nitrosalicylanilide), is a pesticide that is used in conjunction with TFM (4-Nitro-3-(trifluoromethyl)phenol) to treat streams tributary to the Great Lakes that are infested with invasive parasitic sea lamprey (Petromyzon marinus). The application TFM with 0.5 to 2.0 percent (%) Bayluscide can significantly reduce the amount of
Data and code release: Acute toxicity of TFM to multiple life stages of Obovaria subrotunda, its host (Percina maculata), and a surrogate species (O. olivaria)
The risk of lampricide applications (such as 4-Nitro-3-(trifluoromethyl)phenol, TFM) to non-target fauna continues to be a concern within the Great Lakes Fishery Commission sea lamprey control program, especially among imperiled aquatic species—such as native freshwater mussels. The Grand River (Ohio) is routinely treated for larval sea lampreys (Petromyzon marinus) and this river contains populat
