Crayfish plague has been found on Dorset’s River Allen following an investigation by the Environment Agency and Dorset Wildlife Trust.

This is a fungal disease caused by Aphanomyces astaci and it has infected the native White-clawed crayfish in the river. Iodophors have been shown to be effective for disinfection of contaminated equipment, which should be cleaned before disinfection. Thorough drying (for more than 24 hours) is also effective as the fungus is not resistant to drying.
 
The Environment Agency is recommending that any equipment used in the river is clean and dry before use.
We recommend using our FAM 30 for disinfection (after cleaning) of equipment / nets at a dilution of 1:100 to be followed by rinsing in clean water and drying.
