Bluefin tuna fishermen release a flare in their own inflatable during a Greenpeace action. Greenpeace activists attempt to free endangered bluefin tuna from a large cage bound for a Mediterranean bluefin tuna farm. The activists met a great deal of resistance, including the firing of flares from the fishing vessel and use of water cannons by the Maltese Navy. 80% of Mediterranean bluefin is estimated to have already been fished out.
