Belize’s Seaweed Industry: Growing the Blue Economy, Naturally

By Brian McGuire

Belize’s Blue Economy is evolving from concept to action and seaweed farming is at its heart. Along the southern coast and offshore cayes, small-scale farmers are cultivating Eucheuma cottonii and Eucheuma isiforme, two local species that hold remarkable potential for both people and planet.

Belize’s seaweed industry is still emerging but already shows promise as a climate-smart, community-driven enterprise. Seaweed farms naturally filter seawater, provide shelter for marine life, and help restore reef ecosystems — all while creating new income for coastal families, especially women and youth.

Belize’s warm waters and clean reef systems produce premium-quality seaweed, free from mainland runoff and rich in minerals and antioxidants. These conditions allow Belizean sea moss to stand out in the global wellness markets, where sustainable sourcing and traceability matter more than ever.

Still, growth requires structure: better post-harvest processing, consistent quality control, and formal recognition of seaweed aquaculture within Belize’s Blue Economy strategy. With the right investment and policy support, this small industry could become a model for regenerative ocean farming in the Caribbean.

At Belize Blue Nutrients, we’re proud to work with local cooperatives, farmers, and government partners to expand this opportunity — cleanly seeding and harvesting along Belize’s islands, while helping build a transparent, sustainable value chain from reef to market.

The future of Belize’s Blue Economy may be rooted in the ocean itself — in every strand of seaweed that nourishes people, protects coasts, and powers a sustainable future.
