TJ, thanks for taking the time to post that helpful info. Do you have lots of crevice structure for the crayfish to escape the SMB? I was about ready to stock SMB to help control crayfish but maybe I need to think that over some more.
Strange thing is that I have no rocks or crevices, not a single weed anywhere and only fallen leaves for crayfish to hide in and yet I don't seem to get crayfish reproduction. Maybe it is water quality or characteristics (hardness, ph, etc?)
The biggest fish in the pond are the 12 or 13" perch so perhaps they could be eating any baby crayfish but not sure why I never see them and can't get them to go in traps.
Sounds like single sex LMB is one of the best ways for you to go.
