More and more fishing vessels are being drawn to the South Pacific each year,
as this is one of the last oceans where healthy numbers of fish still remain. But for how much longer? Fishing is now a high-tech operation, with radar picking up distant flocks of birds that indicate fish feeding below. The net is paid out in a wide circle around the fish. It's a race against time, as the fish could disappear at any moment. As the circle closes, pellets of dye are dropped into the water.
