What can I do?

Like the Zebra Mussel (Dreissena polymorpha) Asian Clam has the ability to become highly invasive in a short period of time and at high densities it can alter the food web and compete with native mussel species.

This species was listed as a Most Unwanted potential invader by the Invasive Species Ireland 2007 risk assessment and as one of 13 priority potential invasive species by the EPA STRIVE invasive species project.

If you see this species please take a photograph, note its exact location and submit a record either to the National Invasive Species Database if your location is in Ireland and to CEDaR online recording if you are in Northern Ireland.  The information will be passed on to the relevant experts for verification and can help in preventing the spread of this highly invasive species.
