| 内容記述 | Nori aquaculture is one of the most significant fisheries industries in Japan. However, the production of dried nori sheets has continuously been decreasing since 2000’s due to high water temperature in an early aquaculture period (Oct. to Nov.), oligotrophication throughout the season and predation by herbivorous fish and birds. The genetic diversity of nori strains used for aquaculture is low, making it difficult to breed new beneficial strains against the climate change. So, we focused on “biostimulants,” which have been known to give various plants some tolerance to abiotic stresses. In a series of our experiments, amino acids were evaluated as biostimulants for nori culture. We conducted three experiments based on the scheme of land plants using biostimulants: 1) screening of amino acids that are effective for the growth and survival of axenic nori protoplasts, 2) laboratory culture experiments in the presence of bacteria, and 3) field aquaculture trials. Moreover, prior to the field trials, we confirmed the effectiveness of a method of soaking the conchospores in tank seawater where each amino acid was dissolved to avoid using large amounts of amino acids when they are directly added into the area of aquaculture practice. As a result of the screening test, nori protoplasts treated with arginine or ornithine showed rapid growth. Under the condition of bacteria’s existence, these two amino acids enhanced the adherence strength of nori thalli just by once soaking for 15 h. In the field trials, soaking conchospores in arginine or ornithine for 24 h enhanced not only the adherence strength but also the growth of nori blades, which increased the production of nori sheets by 1.1 to 1.3 times. We clarified that arginine and ornithine are the useful biostimulants in nori aquaculture, especially for enhancing the adherence strength and growth in an early aquaculture period and increasing the nori production. | |||||||||||||||||||||
