Briefings
A 2026 study published in Cell Reports Sustainability surveyed 40 sites along the East African coast (Kenya to Mozambique) comparing seagrass and coral reef ecosystems. Researchers found that while reefs support greater fish biomass, abundance, and richness, seagrass meadows offer a richer mix of nutrients for human sustenance. The study authors concluded that protecting seagrass meadows should be prioritized for public health and food security, noting they are 1.6 times more nutritionally multifunctional than reefs when accounting for fish biomass and depth.
Key points
- Researchers surveyed 40 sites along the East African coastline from Kenya to Mozambique, comparing seagrass and coral reef ecosystems.
- Seagrass meadows provide a richer mix of nutrients for human sustenance compared to reefs, which support greater fish biomass, abundance, and richness.
Context
This study challenges traditional views on marine conservation by prioritizing human nutrition over total fish biomass. It highlights seagrass meadows as critical for coastal food security and public health, with lead author Benjamin Jones emphasizing that reliable access to nutritious fish is as important as fish abundance for vulnerable communities.
Limitations
Evidence is limited to a single study published in 2026 in Cell Reports Sustainability covering only 40 sites along the East African coast. The study does not include long-term data, nor does it account for all fish species or human consumption patterns, limiting generalizability.
