Lampricide
Encyclopedia
Lampricide is a chemical which is designed to target the larvae of lampreys in river systems before their recruitment as parasitic adults. TFM
( 3-trifluoromethyl-4-nitrophenol) is one such chemical. http://www.science.mcmaster.ca/Biology/Harbour/SPECIES/SEALAMP/CONTROL.HTM While effective in that it typically doesn't harm other fish due to the evolutionary relationship between true fish and lampreys, lampricides can be problematic for amphibians such as mudpuppies
(genus Necturus
) which often share the same habitats. Also, some more "primitive" species of fish, such as the sturgeon
in the Great Lakes
are sensitive to chemicals such as TFM.
TFM (piscicide)
TFM is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish.The substance was discovered in 1958 when researching means to combat sea lampreys and it remains the primary lampricide in the Great Lakes area.TFM is nontoxic to humans and other mammals...

Mudpuppy
Mudpuppies or waterdogs are aquatic salamanders of the family Proteidae. Their name originates from the misconception that they make a dog-like barking sound. The range of the genus Necturus runs from southern central Canada, through the midwestern United States, east to North Carolina and south to...

Sturgeon
Sturgeon is the common name used for some 26 species of fish in the family Acipenseridae, including the genera Acipenser, Huso, Scaphirhynchus and Pseudoscaphirhynchus. The term includes over 20 species commonly referred to as sturgeon and several closely related species that have distinct common...

Great Lakes
The Great Lakes are a collection of freshwater lakes located in northeastern North America, on the Canada – United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario, they form the largest group of freshwater lakes on Earth by total surface, coming in second by volume...
