Jornal Do Brasilia - Divers fish deadly 'ghost nets' from Santorini's depths

"These abandoned nets are like fish traps," said diver Mika Panagiotopoulou, one of a group of volunteers who have been descending up to 45 metres to fish out discarded nets, tyres and plastic bags from the crystalline blue waters.

"For half a century the build-up of these abandoned nets has swept up thousands of fish and caused incalculable damage to the flora and fauna of our seas," said Santorini's mayor Antonis Sigalas, as the rubbish was gathered up at the little port of Vlychada before being recycled.

"For World Environment Day we want to highlight the dangers of abandoned fishing nets for our seas," said George Sarelakos, co-founder of Aegean Rebreath, the Greek NGO behind the clean-up.

"Discarded fishing nets account for about a tenth of the world's marine pollution and it's a real challenge because up to now it has been invisible -- because most people have no idea of what in hidden in the depths," he added.

Over the last five years, Aegean Rebreath's 300 volunteer divers have removed more than 28 tonnes of nets and hundreds of thousands of plastic bags -- one of the greatest scourges of the aquatic world -- from Greek waters.

Despite a tax being levied on plastic bags in Greece since 2018, shops still hand them out with abandon.

However, Sarelakos said there has been some progress. "There has been a change of mentality among fisherman and now they are handing (nets) over to be recycled."

"It is hard for a fisherman to survive so they put down more and more nets, which leads to fewer fish. It's a vicious circle," he said.
