Abstract
Seaweed cultivation or phycoculture has been developed rather fast in recent years. The total production of cultivated seaweed at present is about 6250×103 tons fresh weight. The total cultivation area is estimated as 200×103 hectare. The annual total value of cultivated seaweeds has been estimated to be more than 3 billion US dollars. Phycoculture provides many job opportunities for the coastal region people, has the potential to improve marine environments and thus even induce global change. All traditional cultivation methods and techniques are based on or start from the individual plant or the cultivated seaweed population. Modern biological science and biotechnology achievements have benefited agriculture a lot, but traditional seaweed cultivation has not changed much since its founding. This is because seaweed cultivation has been quite conservative for quite a long period and has accumulated many problems requiring solution. Four main problems might be the most universal ones holding back further development of the industry. New ways of seaweed cultivation must be developed, new techniques must be perfected, and new problems solved. This paper mainly discusses the main problems of traditional seaweed cultivation at present and its possible further development and reformation in the future.
