TFM (3-trifluoromethyl-4-nitrophenol) is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish. [1]The substance was discovered in 1958 when researching means to combat sea lampreys and it currently remains the primary lampricide (lamprey-killer) in the Great Lakes area.
The mucus and serum of several lamprey species, including the Caspian lamprey (Caspiomyzon wagneri), river lampreys (Lampetra fluviatilis and L. planeri), and sea lamprey (Petromyzon marinus), are known to be toxic, and require thorough cleaning before cooking and consumption. [101] [102]
One lampricide is used in the headwaters of Lake Champlain and the Great Lakes to control the sea lamprey (Petromyzon marinus), an invasive species to these lakes. [1] TFM (3-trifluoromethyl-4-nitrophenol) is the main chemical used for this purpose. As it is hydrophobic, it passes through biological membranes. [2]
The Miller lake lamprey was presumed extinct in 1958, after state fishery managers attempted to eradicate the lamprey from the lake because it was feeding on the introduced trout. [5] The known larval streams for this lamprey were treated with lampricide [6] and a barrier was erected to prevent adults from entering to spawn. [7]
