N2 - Different propagation techniques for cultivation of vegetative Gigartina skottsbergii fronds were tested using a system of suspended ropes, to which inoculants were attached. Our results showed that triangular fragments obtained from the circular G. skottsbergii thalli produced harvestable frond of 800 cm2 after 8 months. In contrast, inoculants of intact juvenile fronds of comparable size needed at least 10 months to reach the same size. A control experiment with spores developing on an artificial substrate showed that 20 months were needed to reach a surface of 500 cm2, confirming the superiority of our fragment culture system. A pilot study demonstrated that with a density of six fronds m−1 of farming line, the proposed system can be economically interesting for local fishermen.
