Brown and black bullheads: Application of a biocide Control of Freshwater Invasive Species

A study in 2014 at a fishery in Essex, UK (Environment Agency Invasive Species Action Group 2014) reported that use of a piscicide containing rotenone achieved eradication of black bullhead Ameiurus melas.  The piscicide was applied using a boat and a bank based application system. Dead fish were removed using nets.  During and after the operation, regular water samples were taken to monitor the level of rotenone.
