Prenfish Fish Toxicant (5% Rotenone)


Prenfish Fish Toxicant is a piscicide designed to control invasive fish species. Featuring rotenone, a general use piscicide derived from the cube resin root used by native populations for centuries, Prenfish™ effectively controls all fish species without affecting most mammals, birds and vegetation when applied as directed. It will degrade quickly in the environment, making it the ideal choice for maintaining balanced ecosystems.This fish toxicant, available in an emulsifiable liquid formulation, can be counted on for a uniform and accurate application of rotenone when sprayed. Prenfish Fish Toxicant can be applied with multiple methods, both undiluted and mixed.

Treatment areas include rivers, ponds, lakes, streams and reservoirs.

Underwater application may be made with a boom or other mechanized equipment, aerial spray, backpack spray, hand-held or hand-directed nozzle and drip can.
