Seaweed farming provides a sustainable way of life for coastal villagers and is an alternative livelihood for families that would otherwise rely on fishing.
The farming method is very simple, yet incredibly practical. Long lines are set up and are attached to poles at each end. Plastic bottles are used to float the lines ensuring the seaweed attains enough light to grow quickly. Seedlings are attached to the lines and grow suspended on them. The seaweed’s colour changes based on age and variety – orange, yellow, brown and green.
Seaweed has many uses apart from being a source of food; it is also harvested for its extracts including, alginate, agar and carrageenan, which are gelatinous substances used in both the food and pharmaceutical industries.

Better yet, seaweed farming, or seafarms, are great for removing phosphorous from the excessive fertilisation of land-based crops. They are also seen as a possible way to help feed the growing world population with a nutrient-rich source of plant matter in the future.
