I think it is best to target harvest mostlythe female BG to help reduce recruitment of BG. Note male-female BG are often not recognizable until the BG grows to 7.5-8". There are several older posts here describing recognizing male vs female BG. In this link to the PB Archives are lots of discussions of growing big BG and a few posts of how to recognize male vs female BG.
