Chemicals can be used to eradicate small, isolated populations of pest fish quickly (spot removal) and with a moderate cost, provided that the benefits clearly outweigh any harm to native species and the environment. There have been a number of attempts to control pest fish in Australia and almost half of these have included the use of chemicals (fish poisons are known as ‘piscicides’). Examples are the successful eradication of carp from Tasmania in the 1970s and from the Cooper Creek drainage in South Australia.
