Following on from the earlier series 'Trawlermen', documentary series `Trawlermen: Hunting the Catch' follows fishermen around the clock as they embark on deep-sea fishing trips. From Shetland to Cornwall, and from the North Sea to the English Channel, cameras follow fisherman as they traverse 300,000 square miles of ocean. Each episode follows a different British fishing boat over the course of a single week as they battle the elements and hunt for a catch that will pay off for the skipper and the crew.
