Sheila Dillon follows two Cornish oyster fisherman, Rob Searle and Tim Vinnicombe, as they travel to the 'Slow Fish' gathering in Genoa - the world's largest gathering of fishermen and women from around the world, organised by the Slow Food movement. Rob and Tim are part of a team attempting to save the tradition of gathering native oysters from the Fal Estuary. The oysters are fished in 200-year-old sailing boats as no mechanical power is permitted on the fishery. By taking their catch to Genoa, they hope to raise the profile of the native oyster and create a market that will help ensure the survival of a traditional and sustainable form of fishing.
