More than 6,000 concrete blocks and thousands of synthetic ropes, which are used illegally by traditional Mediterranean fishing vessels and then abandoned at sea, have been recovered from Greek waters in recent years.
Abandoned fishing gear makes up a significant share of the waste that ends up on the seabed. Its removal is at the heart of the Fishing For Litter programme, run by the Athanasios C. Laskaridis Public Benefit Foundation, in partnership with the environmental organisation iSea.
