Data Release: Evaluation of Bayluscide 20% suspension concentrate formulation field performance (Indian River, Schoolcraft County, MI) Data Release: Evaluation of Bayluscide 20% suspension concentrate formulation field performance (Indian River, Schoolcraft County, MI)
The sea lamprey, Petromyzon marinus, is a parasitic, invasive fish of the Laurentian Great Lakes. Since the late 1950s, the Great Lakes Fishery Commission has administered a Sea Lamprey Control Program (SLCP) that is executed collaboratively by the United States Fish and Wildlife Service and Fisheries and Oceans Canada. This program relies on two lampricides, TFM (4-nitro-3-...
Evaluation of multiple sedation techniques on invasive carps and native fish species in summer 2023 and 2024 Evaluation of multiple sedation techniques on invasive carps and native fish species in summer 2023 and 2024
This study evaluated three sedation methods to determine their efficacy for use during telemetry tagging. Five fish species (bighead carp, grass carp, bigmouth buffalo, American paddlefish, and lake sturgeon) were sedated using eugenol (AQUI-S® 20E), dissolved carbon dioxide, and electroanesthesia to determine sedation induction times. After sedation, half of the fish from each treatment...

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...

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...
