Türkiye’s Sea of Marmara is facing simultaneous outbreaks of mucilage and jellyfish, disrupting the fishing season and damaging marine ecosystems, experts have said.
Fishermen report torn nets and slime-coated gear, with jellyfish density up to 10 times higher than last year.
Oxygen levels have dropped to just 0.3%, threatening marine life.
Experts blame global warming, pollution and nutrient overload.
The government’s 2021 cleanup effort initially curbed mucilage, but the issue resurfaced in 2024. Scientists urge stronger wastewater treatment and pollution controls.
