Healthy Seas Annual Report 2025: Key Highlights
The Healthy Seas Foundation has released its 2025 Annual Report, presenting the results of another year of coordinated action to remove marine litter, promote ocean education and advance circular solutions.
Rather than being defined by a single flagship initiative, 2025 was marked by continuity and sustained effort, with projects carried out across multiple regions and often in parallel. Clean-ups, scientific observation, education programmes and collaborations with local communities and industry partners continued to shape the foundation’s activities throughout the year.
2025 at a Glance: Global Impact in Numbers
In 2025, Healthy Seas operated across 20 countries and seven regions.
Key results from the year include:
- 213 active days in the fields;
- 81.1 tonnes of marine litter collected;
- Collaboration with 1,250 fishers and fish farms to tackle marine debris;
- 13,339 children engaged through educational programs, fostering ocean stewardship;
- 550 divers volunteered during;
- 73 educational events organised worldwide
- 140 days of diving operations.
These results reflect a cumulative effort rather than isolated achievements. Beyond the numbers, the work contributes to cleaner habitats, shared knowledge and long-term collaborations with the communities where Healthy Seas operates.
Addressing Marine Pollution: Tackling Abandoned Fish Farms
Removing marine litter from the ocean remains at the core of Healthy Seas’ activities. Alongside targeted clean-ups along coastlines and underwater sites, the organisation continues to address more complex sources of pollution, including abandoned aquaculture infrastructure.
In 2025, Healthy Seas carried out its fifth abandoned fish farm clean-up, this time in the Methana area in Greece, following previous operations in Ithaca, Patras and Menidi. These repeated interventions highlight the complexity of addressing abandoned aquaculture infrastructure and the importance of long-term collaboration with local partners to effectively manage this type of marine pollution.
Education and Awareness: Engaging Future Generations
Education remains a central pillar of Healthy Seas’ work. Through workshops, school programmes and collaborations with educational institutions, Healthy Seas connects field experience with learning activities that raise awareness of marine litter and encourage a deeper understanding of ocean ecosystems.
Among these initiatives, a series of workshops was developed in Slovenia in collaboration with Eco-Schools Slovenia and Aquafil SLO, focusing on marine conservation, material cycles and circular economy principles.
“Educational workshops on circularity conducted by Healthy Seas managed to bring a fresh take on the teaching process to the classrooms. The result: the students transformed from ‘I could not care less’ to the ambassadors of circular products.” – Tina Mavrič, Marketing and Public Relations Specialist at Aquafil SLO
As a founding partner of Healthy Seas, Aquafil is proud to support initiatives that promote concrete, conscious action and help share these values with new generations, advancing practical solutions to reduce marine pollution and encourage responsible resource management.
