I have done it for experiments. In most instances females already in berry where brought inside to incubate young. The young where then placed in rather large plankton cultures so they could advance through some instars to get more size. This was done to make so I had a better handle on the number of crayfish stocked that actually survived the first day. Only a couple of times have I pulled off the first mating through independence with crayfish like you have in Canada. The crawfish like down south are easy as pie to bread even in Tupperware bowls. There is still a procedure, but simple.
