The legal Japanese longliner 'Keisei Maru No 53' is at sea in Micronesian waters. Shark fins dry on the deck. Greenpeace members go onboard the vessel and talk to the fishermen. Sharks, turtles and seabirds are often caught up as unfortunate victims, or by-catch, of longline vessels. Greenpeace are on the Pacific Leg of the 'Defending Our Oceans' global expedition. They are calling for an immediate end to pirate fishing, a 50% reduction in the amount of Pacific tuna caught, and a global network of Marine Reserves. Yellow Fin and Big Eye tuna stocks in the Central and Western Pacific are destined to be critically over-fished within three years if the relentless fishing of the two Tuna species continues at current rates.
