Fishermen aboard the Newlyn Crabber the 'William Harvey'.

After making the three hour journey to the area surrounding Wolf Rock lighthouse, which is approximately eight miles off Lands End, the three man crew of the 'William Harvey' start hauling in and emptying the crab pots.

The crabs are mainly female and are taken back to Newlyn the same day, where they are stored in sea water holding tanks for a short period of time before they are processed.

Shellfishing does not damage the environment and anything caught that isn't big enough is returned to the sea alive to carry on breeding.

W. Harvey & Sons, who own the boat and processing sites in Newlyn, are the UK's largest shellfish provider.
