Cedar,
Since I’m generally wading when crabbing, I put them in a Costco plastic garbage sack or mess bag that I tie to my wading belt.
Their claws puncture enough holes in the plastic bag that they get good water circulation from being in the water the entire time.
Once I get back to the rig, I put them in a cooler with a small bit of ice.
After leaving the beach and waiting in the ferry line it was a couple hours until I got home yesterday.
Both were still well alive and ready to do battle when I got home and took them out of the bag.
Hope this helps.
