Dear Etienne, Tom and Jean-Pierre and others,

Procambarus clarkii is known in Belgium only from two specimens, one found in a pond in 1986, the other in a small lake in 1996 in in a bad state. Since then, no other records of this species in the field. This crayfish originates from Louisiana and appaers not to withstand the winter in our country Thus, no problem.

Athyaephyra demaresti was present in thge River meuse, but seems not to have been found again since the beginning of the present decade. If it is still present, it must be in very small numbers. It is a deposit-feeder.
