Environmental restoration experiments using aeration combined with coastal bioremediation have been conducted in Omura Bay, an enclosed bay being suffering from hypoxia formation in the bottom water every summer, as a model area. Monitoring of nutrients, red-tide outbreaks, and microbial activities related to oxygen consumption has been made in parallel with the monitoring of hypoxia formation in the bottom water. The effectiveness of the restoration was synthetically evaluated and a practical plan for restoring sustainability and autonomous regulation of the Omura Bay ecosystem was newly proposed. Following our proposal, Nagasaki Prefecture will start practical field experiments in Omura Bay from the fiscal year 2014 as a part of the Action Plan for Environmental Conservation and Regional Promotion of Omura Bay.

大村湾是一个封闭的海湾，每年夏天底层水都会缺氧，作为一个模型区，在大村湾进行了利用曝气与沿海生物修复相结合的环境恢复实验。 在监测底层水中缺氧形成的同时，还监测了营养物、赤潮爆发和与耗氧有关的微生物活动。 对恢复效果进行了综合评价，并提出了恢复大村湾生态系统可持续性和自主调节的可行方案。 根据我们的提议，长崎县将从2014财政年度开始在大村湾进行实际的实地试验，作为大村湾环境保护和区域促进行动计划的一部分。
