Carter Yamanguchi, Palauan law enforcement official, is seen on board a Greenpeace helicopter during a joint operation searching for illegal fishing vessels at sea in the Exclusive Economic Zone (EEZ) of the Pacific island nation of Palau, 08 December 2011. Yamanguchi's keen eyes spotted the Taiwanese long line fishing vessel, 'Sheng Chi Hui No. 7', which is suspected to have been shark finning contravening Palauan law. Palau waters were established as a shark sanctuary in 2009. The Greenpeace ship 'MY Esperanza' is on a three month expedition to expose and stop destructive fishing practices, and to protect dwindling fish stocks in the Pacific.
