Determination of the seasonality effect on sea lamprey and TFM efficacy – Year One (data) Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with of 4-Nitro-3-(trifluoromethyl)phenol (TFM, a lampricide) is essential to reducing the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries. An important component of treating streams with lampricide is ensuring that the proper amount of TFM is applied, effectively controlling sea lamprey populations while minimizing effects on non-target species. In this study, the Trout, Ocqueoc and Sucker Rivers, were selected to complete replicated stream-side bioassays in May, July, and September 2021 to determine seasonal changes in sensitivity to TFM. Larvae were collected and bioassays were... Categories: Data; Tags: Michigan, Great Lakes, biota
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 control sea lamprey populations and minimize the effects on non-target species. In this study, replicated streamside bioassays were conducted in May, July, and September at six sea lamprey infested rivers in Michigan to determine potential seasonal changes in sensitivity of lamprey to TFM. Larvae (≥ 60 mm) were collected with backpack...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
