Crabs like raw liver, bacon, fish heads/tails, chicken or sand eels (someone also suggested cat food!)

Make sure that your bait reaches the sea bed and avoid seaweed if you can.

As soon as you get your crab above the water it will try to jump off. Bring your line out of the water very, very slowly.

Using a net can be useful to land the crabs before they jump off the line.

Make sure that your bucket is half full of sea water and place some seaweed in to shade and protect the crabs.

Crabs don't like over-crowding. It's cruel. Current thinking is ten crabs at most, then let them go.

Change the water once an hour.

Shade your crabs from direct sunlight.
