Abstract

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 Pseudorasbora parva (Temminck & Schlegel), which poses a high overall risk ( Copp 2005 ) and a particularly serious fish disease risk ( Gozlan, St‐Hilaire, Feist, Martin & Kents 2005 ; Pinder, Gozlan & Britton 2005 ). The introduction of topmouth gudgeon to a tarn near Kendal, Cumbria, Northwest England (54°21′ N, 2°47′ W), probably as a contaminant of fish stocked into the tarn in 2000 and 2002, raised concern because this small natural lake (2 ha) is connected intermittently to a water course that passes through a Special Area of
