Asian Top-mouthed Gudgeon Homework

[tigermoth]

Hi all
Wierd request from my daughter: SHe and a school friend are trying to find out about a fish called the Asian Top-mouthed Gudgeon. This is apparently an invading species which does all kinds of untold damage to game fisheries and our native species. Jen would like to know if any of you anglers out there have direct experience of this beastie or know anything more about it.
Ta for any info
Dave
