Outline of Final Research Achievements

In the present study, we proved that optimal temperature, irradiance, photo period and cell mass size for formation and growth of the cell masses, seedlings and full-grown thalli of brown macroalga Analipus japonicus in the Land-based cultivation under three-dimensional (free-living) conditions. In addition, partially drying of the cell masses was an effective method for their low temperature storage. These findings indicate that the Land-based cultivation system using the methods described above is applicable for the Analipus cultivation.

Academic Significance and Societal Importance of the Research Achievements

長期化する気候変動などにより海の環境は激減しており、海藻類の生産量も減少傾向を示してしている。そこで本研究は、東北太平洋三陸特産の高価格海藻マツモを対象種とし、その養殖生産の全行程（細胞塊株生産、種苗生産、成体生産）に、3次元的な「無基質陸上生産システム」を用いるとともに、養殖株の保存を試みることで、効率的で安定した本種の周年生産技術の確立を目指した。
