At the end of February, a huge, black, plastic object appeared in the Ionian Sea, near the Greek island of Ithaca. It left passers-by and winter swimmers flummoxed – but fishermen and maritime transport professionals knew immediately what it was.
They're no strangers to the remains of fish farms contaminating the seabed. Only in this case, the debris threatened the safety of boats and ships operating in the area. Especially at night, a collision with the large pipe-like object – a cage from an abandoned fish farm – could cause serious harm.
