Captive rearing of WCC at Environment Agency Cynrig Fish Hatchery - Lead organisation: Environment Agency Wales
To breed and or rear white clawed crayfish with a view to releasing into ark sites (sites tbd). Project in second year and small scale at present but proving successful. It is hoped to scale up operations in future years and begin stocking suitable ark sites.
Signal crayfish control – River Wye SAC - Lead Organisation: Countryside Council for Wales and Environment Agency Wales
Within the Welsh part of the Wye catchment Signal crayfish are currently limited to one known population in a small tributary stream and adjacent ponds. A trapping programme has been underway for several years, however the project has progressed to assessing the feasibility of applying natural pyrethrum biocide in the ponds with planned implementation in 2011. Measures will be in place to prevent recolonisation of the ponds from the adjacent stream while methods to control or eradicate Signal crayfish in the stream are further investigated. The potential for the Signal population in the stream to go extinct naturally in the absence of recolonisation from the ponds, due to the stream habitat perhaps being suboptimal, is not ruled out.
