What can kill the sea lamprey?

Sea lampreys can be controlled and killed using several methods, including chemical treatments with lampricides like TFM (3-trifluoromethyl-4-nitrophenol), which specifically target their larval stages in freshwater environments. Additionally, barriers and traps can help reduce their populations, while biological control methods, such as introducing predators or competitors, are being researched. Environmental factors, such as changes in water temperature and habitat degradation, can also negatively impact their survival. However, effective management requires an integrated approach to prevent their resurgence.
