Underwater footage of fish including a shark, trapped in the net while the purse seine fishing trawler Jin Hui No.3 is fishing in the Pacific Ocean. With 70% of the world's oceans overfished or at their limit, the Pacific has some of the world's last healthy fisheries. Greenpeace toured the Pacific between July and September 2004 to engage with governments, industry and Pacific communities and help them protect their ocean from overfishing and piracy.
