A freshly caught Yellowfin Tuna being butchered on the deck of a Korean longliner, the 'Shin Yung 51'. The location is within the Exclusive Economic Zone of the Republic of Kiribati. Greenpeace are on the Pacific Leg of the 'Defending Our Oceans' global expedition. 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. Greenpeace 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.
