Abstract: | Since the establishment of abalone farming, there has been an increase in the demand for Macrocystis as a food source. Therefore, the pressure on natural stock has also augmented and the sustainability of the actual harvesting
practices has been questioned. In this article, an attempt to farm Macrocystis pyrifera by zoospores in northern Chile is described; initially under laboratory conditions and subsequently by cultivation in the
sea. The experiments were executed during 1 year and two different cultivation methodologies were used: a direct and an indirect
method. A maximum frond length of 175 cm was reached and 22 kg m−1of rope was produced after 120 to 150 days of cultivation in the sea. The algae grew under both methodologies, and no differences
in algal length and biomass were detected between the two cultivation systems. However, the direct culture method can be recommended
for productive and practical reasons. |
