Native-Nori: UK-Native Seaweed (Nori) Aquaculture for Nutrient-Dense, Low Resource-Use Foods

愿景：开发水产养殖技术，培育具有上级营养价值和对环境产生积极影响的新型海藻食品成分。 创新：水产养殖技术将包括三个核心步骤; 1。收获野生繁殖海藻，2\。为了在水产养殖系统中使幼藻萌发，3.在潮间带生长系统中生长和收获海藻。每一个工艺步骤都旨在消耗最少的资源，最后一步提供宝贵的生态系统服务，如修复富营养化的沿海沃茨，隔离溶解的二氧化碳，为潮间带海洋生物提供营养和栖息地。 项目重点：该项目旨在评估实施新型水产养殖工艺的技术、经济和环境可行性。Plant Ecology Beyond Land CIC（PEBL）在海藻分析、种子收获和海洋工程方面拥有专业知识。合作者Pontus Research Ltd（PR）在水产养殖方面拥有丰富的专业知识。这项合作的成果将是一项全面的可行性评估，将提供详细的运营计划、环境影响和长期运营这种业务的财务可行性。 目标：-监测、分析和收获海藻发酵剂种子。- 试验将海藻种子培育成幼海藻，并将其转移到渔网上。- 在潮间带部署播种网并监测其生长发育。- 海藻质量、环境足迹和生态系统服务提供潜力评估。 影响：天然紫菜将提供一种新的生产高营养食品（平均25%的蛋白质）的方法，土地使用有限，能源投入低，化学品零使用。此外，海藻的生长吸收了多余的氮、磷酸盐和二氧化碳，为潮间带野生动物创造了新的栖息地。这有可能对环境产生进一步的净积极环境影响。 该项目将使PEBL和PR到2025年产生170万英镑的收入和18个新的就业机会，假设一个30公顷的海洋农场生产16吨/公顷年的干重（DW）（相比之下，大豆的平均产量为2.3吨/公顷年，玉米为5.1吨/公顷年），以2,000英镑/吨原料和45,000英镑/吨干燥和包装的平均价格出售。这个海洋农场将有潜力通过提供生态系统服务创造额外收入，每年分别封存0.32吨/公顷、0.032吨/公顷和4.36吨/公顷的过量氮、磷酸盐和二氧化碳[世界银行集团，2016]。

Vision: To develop an aquaculture technology to cultivate novel seaweed food ingredients with superior nutritional value and a net positive impact on the environment. Innovation: The aquaculture technology will consist of three core steps; 1\. To harvest wild reproductive seaweed, 2\. To germinate juvenile seaweed in an aquaculture system, 3\. To grow-out and harvest seaweed in an intertidal growout system. Each process step is designed to consume minimal resources with the final step providing valuable ecosystem services such as remediating eutrophic coastal waters, sequestering dissolved carbon dioxide and providing nutrition and habitat for intertidal marine life. Project Focus: The project aims to assess the technical, economic and environmental feasibility of implementing a novel aquaculture process. Plant Ecology Beyond Land CIC (PEBL) has the expertise in seaweed analysis, seed harvesting and marine engineering. Collaborator Pontus Research Ltd (PR) has the complimentary expertise in aquaculture cultivation. The outcome of this collaboration will be a comprehensive feasibility assessment that will provide detailed operational plans, environmental impacts, and the financial viability to run such an operation over the long term. Objectives: - Monitor, analyse and harvest seaweed starter seeds. - Trial incubation of seaweed seeds into juvenile seaweeds and transferring these onto nets. - Deploying seeded nets out in an intertidal site and monitoring the growth development. - Assessment of seaweed quality, environmental footprint and ecosystem service provision potential. Impact: Native-Nori will provide a new means of producing highly nutritional food (average of 25% protein) with limited land-use, low energy input and zero-use of chemicals. In addition, the growth of seaweed absorbs excess nitrogen, phosphates and carbon dioxide and creates new habitats for intertidal wildlife. This has the potential to provide further net positive environmental impacts on the environment. The project will allow PEBL and PR to generating revenues of £1.7m and 18 new jobs by 2025 assuming a sea farm of 30 hectares producing a dry weight (DW) of 16 ton/ha\*yr (compared to average production of 2.3ton/ha\*yr for soya and 5.1ton/ha\*yr for corn) sold at an average price of £2,000/ton raw and £45,000/ton dried and packaged. This sea farm would have the potential to create an additional income through providing ecosystem services by sequestering 0.32, 0.032 and 4.36 tons/ha/year of excess nitrogen, phosphate and CO2 respectively \[World Bank Group, 2016\].
