Greenpeace action from the SIRIUS against the pirate longline fishing vessel, ATLANTIC OJI NO. 33, near Ibiza in the Mediterranean. Greenpeace hung wooden turtles and tuna from the longline to protest against the uncontrolled fishing by such vessels of spawning tuna stock, with high incidental by-catch. The buoy at the end of the longline has a radio aerial so that it can be located.
