You'd have to check, but I am

You'd have to check, but I am reasonably sure the native species has special protection that requires a permit to handle, disturb etc.

Native Crayfish

The native White-clawed Crayfish is fully protected under the Wildlife and Countryside Act, a licence from Natural England, SNH or CCW is required to trap, handle or "disturb" the species. It is a rare species these days and you are much more likely to encounter the introduced Signal Crayish in most watersheds.

Trapping of ANY species of crayfish, native or not, also requires a permit from the Environment Agency. EA permit tags giving details of the licence and licence expiry date must be fixed to each and every trap used. Unlicenced traps can be seiazed by EA staff or water baliffs.

Crayfish identification and protection

I'll see if we can get a better image (without disturbing them - the river is clear and shallow, so should be no problem). I can assure everybody that my son returned the crayfish promptly, with the minimum of disturbance, and did not physically harm it in any way. Also, it was caught by hand (using a net), and not a fixed trap. I've stressed to him the protected nature of the native (and all) species; the tension is of course between allowing my son to engage with nature "hands-on"(by fishing in streams etc) and complying with protection.
As extra information, we're far upstream on the Cherwell (it rises only a few miles away near Charwelton) - would this make it more likely we have the native species as the "invaders" may not have made it yet?
