Water Users To Help Limit Spread Of Crayfish Plague
Water users are being urged to take precautions to help limit an outbreak of Crayfish plague on River Suir, downstream of Clonmel to Carrick-on-Suir.
It comes after large numbers of dead freshwater crayfish were reported on the river earlier this month. DNA analysis has now confirmed that the cause of death was crayfish plague.
The kill has only impacted White-clawed Crayfish and other freshwater animals are not affected. This is a characteristic feature of the disease which only infects species of crayfish but causes 100% mortality.
All agencies including the National Parks and Wildlife Service, Inland Fisheries Ireland and Tipperary County Council will be working to contain the outbreak to this stretch of the River Suir. Given the experience of outbreaks elsewhere, a total kill of the population is expected which will have major consequences for the ecology of the river. Crayfish are very common in the Suir and are important in maintaining its ecology.
Anyone using the river is being urged to observe the 'Check, Clean and Dry' protocol once they leave the river and before using it again. This means that all wet gear (boats, clothing and equipment) should be checked for any silt or mud, plant material or animals before being cleaned and finally dried. Disinfectant or hot water (over 40 degrees Celsius) should be used to clean all equipment and this should be followed by a 24-hour drying period.
The drying period is especially important in ensuring that all equipment is clear of infectious organisms, including the removal of any water inside the boat. The crayfish plague organism can be carried on wet equipment to new sites and containment of the outbreak is essential to prevent spread to other unaffected populations in Ireland.
This is the second confirmed outbreak of the disease in Ireland following one in County Cavan in 2015. There is no indication of how the disease reached the Suir although a link to the Cavan outbreak is considered unlikely. This outbreak on the River Suir is of concern as the stretch of river affected is popular with anglers and canoeists.
