Okay, that is where I am getting that from then...I grew up in VA and had it drilled into me that keeping females were bad, even bad tasting...I've had a few slip in but can honestly say any I've caught or bought I've always insisted on male crabs...is it true then that after the she crabs have dropped their sacks they don't produce again?
Females mate only once during their terminal molt. A mature female (Sook) can store the males crabs sperm for multiple spawns. It has been documented in the lab that a female crab has spawned 8 times on a single mating.
"Although a female will mate only once, she may produce many fertilized egg masses during her lifetime from this single mating. Fertilization occurs each time a new egg mass is produced by the ovaries until the sperm reserves are depleted. Studies in Florida found that some female crabs produce as many as seven broods (sponges) in one year from a single mating, and up to 18 broods over 2–2½ years. Chesapeake Bay female crabs are capable of producing multiple egg masses over several years, though most will not produce more than one or two masses due to their short average life span, typically 1–2 years."
