A brook in North London was today purposely poisoned in an attempt to kill a damaging non-native species of fish. The Environment agency took the decision after the Topmouth Gudgeon fish was found in Cuffley Brook in Enfield.
Residents have reacted angrily to the news because the poison will kill any fish it comes into contact with. Environmental Health officers will then restock the waters with only the native species.
