I picked up a leaflet today on these fellows from Scottish Natural Heritage (SNH). It seems thay are quite keen to eradicate it from our rivers, lochs etc. However, I believe it is illegal to fish for crayfish without a licence. Does this apply to the Signal Crayfish or can we set traps for it in infected waters? I noted that Mr Mears cooked some recently and they looked fabulous to eat. So can we set traps in Scottish lochs and rivers for these things?
