Keeping Peeler Crabs

Can anyone give any advice on keeping crabs until they peel? I'm wondering if it's possible to catch crabs with a net from a harbour and somehow keep them alive until they molt. Also does anyone know if they would peel around the same time (within a few days of each other) .
I'm thinking of catching a few and trying to keep them alive by placing them in a tray and covering them with a damp cloth, and putting them into a bucket of sea water for an hour every couple of days. Would this work?

if you go on to the sea angler magazine web site alan yates has a good video about keeping peeler crabs

Trying to bring jacks on could be long and expensive business, You would probably have to create a proper habitat in large tanks with pumps and then i don't think its successful.
If my memory serves me right i think i remember reading in an angling magazine something about someone doing something like this, i must have been a failure otherwise we would have heard.
Also i think some of the lads off this site have tried it and failed. Better off finding a reliable source or supplier.
