A freshly caught Yellow Fin Tuna being pumped with water to flush out its blood 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. 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.
