A crew member of the Greenpeace ship MV Esperanza holds an Orange Roughy that has been caught and killed by an EU bottom trawler, the Playa de Menduina, fishing in Hatton Bank, NE Atlantic. Bottom-trawling boats, the majority from EU countries, drag fishing gear weighing several tonnes across the seabed, destroying marine wildlife and devastating life on underwater mountains - or 'seamounts'.Greenpeace is demanding a UN moratorium on bottom trawling on the high seas.
