Fixed-Off Bottom Method
Picture showing how a seaweed line is typically suspended in the Off-bottom Method.
In fixed off bottom method a 3 mm thick polypropylene rope 5 meters long is firmly stretched between two stakes. Attached to the 3 mm rope (line) are 30 pieces of raffia (polypropylene strings). Each of the planting material (seed), the size of the palm (150 grams), is tied to the raffia strings. The 3 mm rope, is suspended at least 20 to 30 cm from the sea bottom to prevent the growing seaweed from being tossed on the sand and 20 to 30 cm below the water surface at low tide to avoid the seaweeds from being exposed to direct sun light. Direct sun light will kill the exposed parts.
