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 \[World Bank Group, 2016\].

愿景：开发一种水产养殖技术，培育具有优越营养价值和对环境净积极影响的新型海藻食品原料。创新：养殖技术将包括三个核心步骤；1\。收获野生繁殖海藻，2\。在水产养殖系统中使幼藻发芽。在潮间带生长系统中生长和收获海藻。每个过程步骤都旨在消耗最少的资源，最后一步提供有价值的生态系统服务，如修复富营养化沿海水域，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一种新型水产养殖工艺的技术、经济和环境可行性。陆地以外的植物生态学CIC （PEBL）在海藻分析、种子收获和海洋工程方面具有专业知识。合作伙伴本都研究有限公司（PR）在水产养殖方面拥有互补的专业知识。此次合作的结果将是一项全面的可行性评估，该评估将提供详细的运营计划、环境影响和长期运营这种运营的财务可行性。目标：-监测、分析和收获海藻种子。-试验将海藻种子培育成幼海藻，并将其转移到渔网上。-在潮间带地点布放种子网，并监察种子网的生长情况。-评估海藻品质、环境足迹及提供生态系统服务的潜力。影响：本地紫菜将提供一种生产高营养食物的新方法(平均25% protein) with limited land-use, low energy input and zero-use of chemicals.
