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...

Data and Code Release:Technical Assistance Bioassay to Compare Sea Lamprey and Logperch Sensitivity to TFM 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...

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...
Data and Code Release: Determination of Larval Sea Lamprey (Petromyzon marinus) Seasonal Sensitivity Differences to Lampricide Treatment Data and Code Release: Determination of Larval Sea Lamprey (Petromyzon marinus) Seasonal Sensitivity Differences to Lampricide Treatment
Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with 4-nitro-3-(trifluoromethyl)phenol (TFM, a pesticide) stream treatments reduces the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries. An important component of stream treatments is ensuring that the proper amount of TFM is applied that will effectively...

The dataset was generated to verify the suitability of the new TFM bar formulation for wide-scale use in the Sea Lamprey Control Program (SLCP). Dataset includes TFM concentrations of three streams (each used twice) where randomized experimental applications of new and old TFM bar formulation dissolution trials were conducted, TFM concentrations of 12 laboratory flume experimental...
Behavioral and Reproductive Effects of the Lampricides TFM and TFM:1% Niclosamide on Native Freshwater Mussels - SPSS Code Release Behavioral and Reproductive Effects of the Lampricides TFM and TFM:1% Niclosamide on Native Freshwater Mussels - SPSS Code Release
This study continues our investigations into the effects of lampricides on mussels by extending research into potential effects on behavioral and reproductive endpoints on the mussel plain pocketbook (Lampsilis cardium). We hypothesized that TFM and TFM:NIC would reduce the viability of free glochidia in a dose-dependent manner, that older glochidia would be more sensitive than younger...

Non-target animal sensitivity remains a concern when treating Laurentian Great Lakes streams with 4-nitro-3-(trifluoromethyl)phenol (TFM), the main pesticide used to control Sea Lamprey Petromyzon marinus as part of the bi-national Great Lakes Fishery Commission's Sea Lamprey Control Program. Populations of Burbot Lota lota, a historically and culturally important fish, inhabit some of...

Acute toxicity of the lampricide 4-nitro-3-(trifluoromethyl)phenol to the Mussel (Obovaria subrotunda), its host (Percina maculata), and a surrogate mussel species (Obovaria olivaria) Acute toxicity of the lampricide 4-nitro-3-(trifluoromethyl)phenol to the Mussel (Obovaria subrotunda), its host (Percina maculata), and a surrogate mussel species (Obovaria olivaria)
The risk of lampricide applications (such as 4-nitro-3-[trifluoromethyl]phenol [TFM]) to nontarget 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, USA) is routinely treated for larval sea lampreys (Petromyzon marinus), and this river...
