It's highly probable that you haven't noticed a molt. If it happens underground, you can only tell from a few signs after they emerge. Signs are a color change, black pointy very sharp toenails....it will feel like a cactus walking up your forearm...and they are quite hairy.
Here's one possible scenario....they went down to destress which could take a few months and they their molting hormones kicked in and they just stayed down to molt....although some of them could be coming up at night. !0 months does sound like an awfully long time.....Let's see what some of our veteran crabbers have to say. Even though my post count is high, I've only been crabbing since September 2007.....I'm just a chatter box!
