A groundbreaking marine conservation initiative between China and Indonesia has achieved significant breakthroughs in coral reef restoration, demonstrating the power of international scientific collaboration in addressing oceanic environmental challenges. The joint research project on marine offshore ecological ranching technology, spearheaded by Shanghai Ocean University in partnership with Indonesian institutions, has transformed degraded marine areas into thriving underwater ecosystems.
According to the latest survey data, coral coverage in the project area near Pulau Bonetambung island in Indonesia’s South Sulawesi province has shown extraordinary recovery. From October to December 2025, coral coverage surged from 10% to 22%, representing one of the most successful marine restoration efforts recorded in the region. Researchers have documented 132 distinct coral species, predominantly from the Acropora and Porites genera, establishing vibrant new habitats for marine biodiversity.
The project’s success extends beyond coral regeneration to encompass the entire marine ecosystem. The research team, led by Professor Liu Bilin from Shanghai Ocean University, reports the return of high-trophic-level fish species including the eight-banded butterflyfish (Chaetodon octofasciatus) and bicolor parrotfish (Cetoscarus bicolor), indicating the establishment of a complete, self-sustaining food chain within the restored area.
Advanced monitoring technologies have been deployed to ensure the project’s continued success. Underwater binocular cameras function as ‘ecological sentinels,’ providing real-time, high-definition monitoring of fish activity, biological distribution, and fouling organism growth without requiring frequent manual surveys. This technological innovation, as explained by Professor Zou Leilei, addresses the traditional limitations of marine environmental assessment.
The project, currently in its second phase (2025-2027), is expanding both technically and geographically. Syiah Kuala University, another Indonesian institution with strong marine science expertise, has joined the collaboration, enhancing knowledge exchange and local capacity building. Training programs and joint research initiatives are being strengthened to cultivate Indonesian expertise in marine conservation, ensuring the long-term sustainability of these restoration efforts.
