Seaweed Productivity in Various Cultivation Systems

Aquaculture

The karaginophyte (which include Eucheuma spinosium, Eucheuma edule, Eucheuma serra, Eucheuma cottonii, and Eucheuma spp.), agarophytes (which include Gracilaria spp., Gelidium spp., and Gelidiella spp.) and alginophytes (which include Sargassum spp., Laminaria spp, Ascophyllum spp, and Macrocystis spp) species are among the many kinds of seaweed that are commonly cultivated, produced, and marketed in Indonesia. In general, the selection of the seaweed cultivation system is adjusted to the prepared cultivation location such as water conditions, material supplies for cultivation construction and the pros and cons of using this method. The method of cultivating seaweed in the field (field culture) can be done with three kinds of methods based on the position of the plant to the bottom of the water. The appropriate seaweed cultivation system will greatly affect the productivity it produces. In addition to the cultivation system, the productivity of seaweed cultivation is also influenced by climate and geography, such as sunlight, currents, pressure and water quality and salt content, which are in accordance with the biological needs and growth of seaweed.
