FADs are made up of a plastic line anchored to the bottom of the sea that keeps large leaves afloat on the surface, attracting fish which gather beneath it.

The fishermen then encircle the FAD with their nets, capturing every fish from the largest to the smallest – and often youngest, a slaughter that respects no limits and is carried out with the use of illegal equipment.

And worse, the propylene line - which by law should be biodegradable - is the cause of death for many turtles, which often get entangled in it and die from suffocation or from the wounds they inflict on themselves trying to break free.

The seas are also plagued by illegal spadare drift nets, true walls of death -- often abandoned at sea -- that unavoidably trap turtles, dolphins, sperm whales, fin whales and sharks.
