The link, rather the law, provided by the other responder sure is crazy. Common sense says take one claw max! Allow the crab to defend and feed itself for gosh sakes. AND it should be NO claws from females, only males. Easy enough to determine sex. - I was with a small Cousteau crew in Panama City, Florida in 1974 when we boarded two stone crab fishing boats and filmed them for a couple days. (It never made it to television.) - I write about it in my book Frogmen. I was astonished that the fishermen took both claws from both sexes, tossing the torso back in the water. Ignorant! And while we were filming them too.
