Rotenone is used in various parts of the world in fish population surveys and fisheries management (Ling 2003; McClay 2005), including the eradication of undesirable fishes (e.g. Amey 1981). In response to continued concern surrounding the risks and impacts of non-native fishes (Copp, Garthwaite & Gozlan 2005), use of this plant-derived piscicide in England and Wales has been considered as one possible measure, in support of existing government policy, to control the spread of non-native freshwater fishes (Defra 2003). Probably the most invasive of the non-native species introduced to the UK since 1950 is the Asiatic cyprinid, topmouth gudgeon

The aim of the present study was to assess the acute toxicity of rotenone to topmouth gudgeon so as to determine the effective rotenone concentration required for complete eradication of the species.
