Aquaculture is estimated to be one of the fastest growing industries in the world and will be even more central in food production in the future. In the future industrial development of Europe, we see an increased focus on a sustainable use of our natural resources. When this is coupled with an ever-increasing need for food production worldwide and a corresponding increase in the amount of high-quality seafood being demanded and consumed, there is a need for improved knowledge to utilise the available marine resources in a sustainable way. Low-trophic and sustainable aquaculture is essential if we are to achieve the goals set by the European Union (EU) and/or each country for food production in (or from) the sea. More and more of this production must come from species that can utilise energy sources such as sunlight and plankton for growth and that do not need additional feed made from species that also can be used directly as human food. There is a common national goal to eat more seafood. Macroalgae as food is quite new or unknown to people in Western Europe, and this project aims to give basic skills on this subject to the students and teachers involved. In addition, it is a project goal to tell and teach the public about macroalgae. Farming of macroalgae is a stated focus area in the partnership countries Norway, Denmark and Ireland, and the ambitions is quite high. A report from SINTEF Ocean (October 2017) estimate the production potential for macroalgae to be 90 000 tons for Trøndelag county (Norway) alone.The 11 partners in this intersectoral two year partnership project have different approaches to macroalgae; teaching and training, natural science, research and development, seedling and farming of macroalgae, processing and distribution of products. This open up for a broad view on new knowledge, and how this can be utilized among the partners and also spread to other stakeholdres. The different approaches is a strenght when it comes to further development of the macroalgae industry, as there is a need for different competences at different levels.Macroalgae is an international industry, with a total production of 30 million tons a year. Asia is the main producer and consumer, and macroalgae is not so common in Europe yet. There is therefore demand for a common understanding across Europe of how macroalgae can be farmed, used in different ways and its environmental impact. To transfer knowledge among students – as future employees, stakeholders and decision makers – across borders is an excellent start for such an understanding. Students (as future employees) and teachers (as knowledge providers) need updated knowledge and competence about low-trophic aquaculture in general and macroalgae in spesific, to make it a more integrated part in the education programmes. At the Transnational project meetings and LTT activities a total of 150 students and teachers/staff will participate. The LTT activities will have focus on different aspects, such as macroalgae as food, the environmental impacts of macroalgae and macroalgae farming. In addition we aim to have at least 125 participants at four different Multiplier events, organized as open seminars with different topics related to macroalgae. At these seminars stakeholders and policy makers will be invited, along with media and the general public. The seminars will be connected to the presentation and launching of the four Intellectual outputs (IO) in the project. The IO will be in different formats, such as a publication on macroalgae and environment, teaching and training material as hands-on (paper), vodcasts and e-learning book, and macroalgae fact sheets in a populist format easy to read and use for educational purposes as well as information for the general public.The impact of this project will be an increased knowledge about macroalgae as low-trophic and sustainable aquaculture, algae as a sustainable and healthy food resource and the importance in an environmental perspective. The partners / participating organisations will increase their international network and obtain new knowledge which lead to ideas and strategies for the implementation of new teaching and training methods, as well as establishment of collaborative constellations and new partnership/projects. Through dissemination activities and Multiplier Events the project will reach the relevant audience for the Intellectual Outputs from the project and meet stakeholders that have, or develop, an interest in the topics covered by the project. Information about the project in general will be available on the partners’ websites and the project Facebook page, including the Intellectual Outputs produced. The project results will be made available on request. In addition to the project partners, schools in Norway, Sweden, Denmark and Ireland will get access to the project results and be able to use them for free in their organisations.
