The following is advised by an interagency group set up to address Crayfish plague outbreaks in the River Suir (Clonmel, Co Tipperary) and the River Deel (Newcastle West, Co Limerick).


·         Crayfish Plague, which is fatal to our native populations of Freshwater White-Clawed Crayfish has been confirmed in the above catchments.

·         All native crayfish that become infected will die.

·         Ireland holds the largest population of the White-clawed Crayfish that remains in Europe.

·         Crayfish Plague is easily transmitted in water or via contaminated equipment (eg canoes, waders or nets).

·         Crayfish plague may also have entered into other rivers. Emergency disease containment measures are therefore needed to help ensure its containment and prevent its spread.


If movements are essential, all recreational equipment including clothing etc should be thoroughly dried out and the following biosecurity measures followed.

·         All water users are asked to operate a temporary ban on moving water sports and angling equipment out of the River Suir and River Deel catchments - commencing immediately.

·         Water sports and angling equipment currently in use in the Suir and Deel catchments may continue to be used there; but boats, angling or water sports equipment should not be transferred in or out of the catchments.

·         Users are also requested to limit their activity to the river sections where they normally operate, avoid moving around the catchment and follow biosecurity protocols – "Check, Clean, Dry".
