A swordfish caught as by-catch on the end of a bait line of a Korean longliner, the 'Shin Yung 51'. The location is within the Exclusive Economic Zone of the Republic of Kiribati. Many types of billfish, such as this swordfish, sharks, turtles, dolphins and albatrosses can often end up as unfortunate by-catch of longline fishing. 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.
