Absolutely positively correct.
Marbled Crayfish reproduce by parthenogenesis, which is self cloning. Meaning all young, will have identical DNA to the mother cray, and all will most likely be female.
Its a very interesting creature!

I have 4 of them and they grow really quick. Getting aggressive towards each other so I'm getting rid of 3 of them. The largest one is now close to 2". Looking forward for the cloning... LOL

Around 3 is pretty much the norm, once and a while I get one that starts at around 2 and at 4 they are baby machines.

Once they berry, they will become reclusive and typically stay hidden most of the time.
