This Bluefin Tuna died as a result of being caught on a longline which broke, but was still attached to buoys on  the surface. Greenpeace activist showing english banner.

Greenpeace is calling on the countries of the Mediterranean to protect bluefin tuna with marine reserves in their breeding and feeding areas. They would become part of a global network of marine reserves across 40% of the world's oceans that are needed to give the oceans a chance to recover from decades of large-scale industrial exploitation.
