|Section2= |Section3= }} TFM (3-trifluoromethyl-4-nitrophenol) is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish.〔(TFM fact sheet )〕 The substance was discovered in 1958 when researching means to combat sea lampreys and it remains the primary lampricide (lamprey-killer) in the Great Lakes area.〔 TFM is nontoxic to humans and other mammals. Impact on other fish species may be controlled by selective application during the larvae season for lampreys and other management of its concentration. TFM does not accumulate, since it breaks down within several days. 〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TFM (piscicide)」の詳細全文を読む スポンサード リンク
