In the 1980s, locals turned to Eucheuma cottonii farming—a seaweed species rich in carrageenan, a thickening agent used in everything from cosmetics to ice cream. At its peak, seaweed covered vast stretches of Nusa Lembongan’s shores, providing a stable income for thousands of families.

The Step-by-Step Process of Seaweed Farming

If you’ve ever wondered what goes into farming seaweed (besides seawater), let’s break it down:

Selection of Seaweed Strains

Farmers choose high-quality Eucheuma cottonii, known for its strong carrageenan content.

Planting the Seaweed

Unlike traditional farming, no soil is needed! Instead, farmers tie seaweed to ropes and submerge them in the shallow waters. These floating farms create a mesmerizing green landscape in the sea.

Growth & Maintenance

Every few weeks, farmers check for pests and debris. Surprisingly, seaweed farming doesn’t require fertilizers—it thrives naturally in the ocean’s ecosystem.

Harvesting & Drying

Once matured (about 45 days later), the seaweed is hand-harvested, sun-dried on bamboo racks, and prepared for export.

Seeing this process in action is a game-changer—you’ll walk away appreciating that the thickener in your favorite yogurt or toothpaste came from the shores of Bali.
