Hugh goes to the southern oceans to witness the high-tech fishing practices targeting the tiny krill. Hugh travels further than he's ever been before, close to Antarctica and one of the last significant patches of sea not already being overrun with fishing boats. But even here, he discovers a high-tech fishery that is targeting krill, the tiny shrimp-like crustacea at the bottom of the food chain that is being fished for feed that helps turn salmon pink, and also as krill oil tablets - part of the increasingly lucrative health food market for omega 3 products. South Georgia, a haven for wildlife, is governed by the British. This means that it is the British Government who decide how much of this sea to protect. But will they listen to Hugh as he pushes them to set up a bigger protected area around this extraordinary patch of sea?
