Seaweed Farming Culture methods

Seaweed Farming Culture methods

The earliest seaweed farming guides in the Philippines recommended cultivation of Laminaria seaweed and reef flats at approximately 1m depth at low tide . They also recommended cutting off sea grasses and removing sea urchins prior to farm construction. Seedlings are then tied to monofilament lines and strung between mangrove stakes pounded into the substrate. This off-bottom method is still one of the major methods used today.
There are new long line cultivation methods that can be used in deeper water approximately 7 m in depth. They use floating cultivation lines anchored to the bottom and are the primary methods used in the villages of North Sulawesi, Indonesia.
Cultivation of seaweed in Asia is a relatively low-technology business with a high labour requirement. There have been many attempts in various countries to introduce high technology to cultivate detached plants growth in tanks on land in order to reduce labour, but they have yet to attain commercial viability.
