Greek Fish Farms Finally Clean Up Pollution After Pressure

For years, abandoned fish farms have turned parts of Greece's Ionian Sea into underwater junkyards filled with nets, plastics, and timber. But thanks to persistent pressure from environmental groups and journalists, one major cleanup just happened without anyone having to do it for them.

The problem started when fish farmers abandoned their businesses near Ithaca and Modi in western Greece, leaving their equipment to rot in the ocean. These "ghost farms" killed countless fish and created serious pollution that locals watched worsen for years.

Environmental organization Healthy Seas had been tracking one abandoned site near Modi for years, documenting four inactive aquaculture rings just sitting in the water. The group worked with Greek NGO OZON and Ghost Diving Greece to survey the damage and raise awareness.

Then in February 2026, things got dangerous. A massive fish farming ring broke loose and drifted into shipping lanes used by passenger vessels near Ithaca. The Coast Guard had to intercept it and tow it to shore before it caused an accident.

Healthy Seas suspected the drifting ring came from the abandoned Modi site and intensified their campaign. They contacted authorities, increased public exposure, and formally demanded institutional action.

The Ripple Effect

The pressure worked. When the Coast Guard inspected the Modi site again, all the previously abandoned structures were gone. The operator told authorities they had transferred everything to a recycling company, finally taking responsibility after years of neglect.

While the operator denied the drifting ring came from their facility, the outcome remains a win: one more ghost farm removed from Greek waters. Even better, it happened because the operator chose to act rather than waiting for nonprofits to clean up their mess.

"For years our work has focused mainly on the physical removal of abandoned aquaculture infrastructure from the sea," says Veronika Mikos, Director of Healthy Seas. This case proves strategic engagement and institutional pressure can motivate operators to assume responsibility themselves.

The victory reveals a broader issue across the Mediterranean. Aquaculture infrastructure can sit inactive for years while still being considered operational on paper, slowly becoming environmental hazards and safety risks.

The combination of nonprofit persistence, media coverage, and government authority created accountability that finally worked.
