Piscicide

Piscicide

A piscicide is a chemical substance which is poisonous to fish. The primary use for piscicides is to eliminate a dominant species of fish in a body of water, as the first step in attempting to populate the body of water with a different fish. They are also used to combat parasitic and invasive species of fish.

Examples of piscicides include rotenone [ [http://www.chm.bris.ac.uk/motm/rotenone/piscicide.html Rotenone as a piscicide ] ] [ [http://www.fisheries.org/units/rotenone/ Rotenone Stewardship Program ] ] , saponins, TFM (3-trifluoromethyl-4-nitrophenol), niclosamide, bayluscide (the ethanolamine salt of niclosamide), and Fintrol.

Plant-based piscicides

Historically, fishing techniques of indigenous people around the world have frequently included the use of plant-based piscicides. Many of these plants are natural sources of rotenone and saponins.

The Tephrosia, Wikstroemia, and Barringtonia genuses are well-known as fish poisons.
