The topmouth gudgeon can dominate waterways and compete with native fish and mammals for food
Topmouth gudgeon, a species that originated in China and Japan, have been found in 32 locations around the country.
The fish, which are just three inches long, can dominate waterways and compete with native fish and mammals, such as water voles, for food.
They also carry a disease that can kill native salmon and trout (http://www.telegraph.co.uk/earth/countryside/9090827/Salmon-under-threat-from-parasite.html). Fishermen fear the topmouth gudgeon, which can establish populations of hundreds of thousands in a single lake, will destroy water systems if they spread further.
