Guardian of the Coasts: The Vital Role of Seagrass in South Sulawesi Fisheries

MAKASSAR, Indonesia, 31 March 2026/AMBioC/ – Seagrass meadows are vital blue-carbon ecosystems that support marine biodiversity, local fisheries, and coastal resilience. Their ecological importance in the Spermonde Archipelago is highlighted in Chapter 6, “Ecology of Seagrass Beds in Sulawesi—Multifunctional Key Habitats at the Risk of Destruction,” published on 22 October 2022 in the Elsevier book Science for the Protection of Indonesian Coastal Ecosystems (SPICE) and indexed in Scopus.

A Sanctuary for Marine Biodiversity

The waters of South Sulawesi are home to a remarkable variety of seagrass species, such as Enhalus acoroides and Thalassia hemprichii. These plants create a complex underwater structure that provides shelter and food for countless creatures, ranging from tiny crustaceans to valuable food fishes. Our studies show that denser seagrass beds support a significantly higher abundance of marine organisms, including the zebra mantis shrimp. This relationship proves that the quality of the habitat directly dictates the richness of the life it can sustain.

The Threat of Habitat Loss

Despite their immense value, seagrass meadows in Indonesia are facing widespread degradation due to human activities. Coastal development, pollution, and unsustainable fishing practices are thinning these vital green belts. When seagrass density decreases, the entire food web feels the impact. Juvenile fish lose their hiding spots, and the seabed loses its stability, leading to a decline in fish stocks that coastal communities rely on for their daily survival.

Strategic Links to Global Goals

This research is deeply rooted in Sustainable Development Goal (SDG) 14: Life Below Water. By quantifying the link between seagrass density and faunal abundance, we provide the scientific evidence needed for better marine spatial planning. Protecting these habitats is also a contribution to SDG 13: Climate Action, as seagrasses are essential for sequestering blue carbon. Furthermore, maintaining healthy seagrass beds supports SDG 1: No Poverty by ensuring that small scale fishers continue to have a reliable source of income and food security for their families.

Moving Toward Sustainable Management

The future of our oceans depends on our ability to protect these coastal “jungles.” Conservation efforts must focus not only on the size of protected areas but also on maintaining the biological quality and density of the vegetation. Through continued research and community engagement, we can ensure that the seagrass meadows of South Sulawesi remain a thriving sanctuary for marine biodiversity and a pillar of support for our coastal people.
