Been doing a fair bit of crabbing the last few weeks while we had plenty of fresh bait. If we stay and work the pots we get a nice catch over 3 or 4 hours. But if we leave them over night we only seem to get 3 or 4 out of a couple of pots and the rest have been raided. This can be anything from pots taken, bottom cut out or just crabs taken and pots left unclipped
