Wageningen and EFARO on the Green Deal, Farm to Fork and Food from the Oceans 22.1.21 10.00 – 12.00 by Webex Meeting: Wageningen and EFARO on the Green Deal, Farm to Fork and Food from the Oceans 22.1.21 10.00 – 12.00 by webex Welcome from Luc van Hoof, Executive Secretary of EFARO Luc welcomed over 40 participants and experts who had joined to discuss circular food production in our oceans. Start with Professor Louise Fresco, Chair of EFARO: Changing philosophy about changing production and how we see the sea In the least 10-15 years we’ve seen a slow and gradual change in the philosophy on the use of natural resources for food + feed. Concepts like biobased, local, circular have all come into place. It’s pushed by growing distance between urban consumers and the realities of how production and use of resources takes place. There’s also impetus from the Paris agreement, the need to be more carbon neutral, and nature conservation is a goal in itself. This has led to a political shift, e.g. the Green Deal. It’s our task to provide a scientific basis for it. The idea of circularity is complicated. And there are issues of carbon neutrality and positivity (carbon fixing). The overall thing is that this is about quality not quantity. What is circularity: Waste from one trophic level becomes used for another trophic level - resource use efficiency. It also means nutrient efficiency (nitrogen, phosphates etc). Try to develop a more integrated perspective of land based and marine based sources of nutrients. What is the optimal protein base and how to get best proteins for our food? So it’s the whole world of biobased economy. And how to keep communities that are dependent on marine resources in an economic balance - we need a science-based model for the use of marine resources so as they can produce what’s needs for food and health (it’s not just fatty fish, but what other health components can we get). This is really an integrated flow. There are a lot of challenges right now. We need an integrated picture. The marine space is still very much invisible, or often visible from a disaster point of view; the richness of the marine organism in its potential to produce organic compounds needs more attention. Our evolution as human beings has been tied to the marine space – e.g. shellfish. Now we have a chance to say that marine resources are essential for the future. We can look again at how we use our space. We need science-based answers. Video: How are the Dutch dealing with circular food production at sea - how they allocated space at sea to carry out energy, nature and food transition. Moved from land to sea. Energy: licence to operate wind parks at sea; nature: 15% of sea closed to bottom trawling; fisheries and aquaculture are acknowledged and allowed at sea. Video: what’s out there at sea and what is the potential? Prof Jan vaan der Meer of Wageningen. The sea in terms of animal life is more productive than the land, but you don’t see any plant life; what do they live off? Nature on land is very inefficient, whereas at sea it’s very efficient and most of the protein is transferred to fish. His concern is that we’re asking too much of the sea – it’s too optimistic to increase production. Finfish has less potential for improvement. We need nutrient use efficiency. There’s a limited amount of nutrients at sea. One option is to culture seaweed. Examine tradeoffs that exist between the microphytoplankton and all the animals that exist from that. Herbivores (mussels and oysters) are the most promising way. They don’t occur in the open sea. Dennis Lisbjerg DTU Aqua: there are a lot of challenges and a limit to how much we can take from the sea – we’ve had stagnant fisheries and aquaculture in EU waters for decades. But there ARE some possibilities with nature-based solutions, ecological engineering. Examples from open ocean areas where trying to manipulate the system and get the nutrients built up to increase productivity in the oceans; but our knowledge of the oceans is limited. Coastal areas: in some parts of waters in European it’s not a limiting factor in terms of how many nutrients there are, e.g. in DK O2 depletion due to nutrients in the water. So there is some productivity we could utilise. We’ve altered the system through fishing and other use of resources e.g. removal of stone reefs to build harbours, and we’re talking about how to restore/conserve these areas, to increase sustainable harvest from coastal waters. Circularity: in our fishing we depend on system and fish up what’s available, but there’s also aquaculture and seen as an area of where we can get protein from oceans. 1 Example Baltic brand feed innovation - one of examples of how to increase open cage aquaculture from fish coming from the same system. But it’s using smaller fish for feed!!!! Whereas in Norway the fish farmed are becoming vegetarian – it’s not a closed loop, but opening up to use terrestrial feed. More offshore aquaculture can also increase productivity in that area. We need to differentiate coastal shelf areas with open ocean areas. A good case for proteins from the oceans, because it’s productive and efficient in converting food into protein; compared to land based production. When you see the loss, it is the nutrients, and in DK legislation on pig farms is according to how much land you have to distribute the manure, but there’s also leakage of it into the marine systems. We have to remember this leakage from land to marine. Now we talk about mitigation measures to have mussel farms at sea because of all the algal blooms. So it creates a loop. Also trying to develop pre-circulating systems – fish on land, and you have to feed them something - but is this food from the ocean, even though it’s come from a land-based farm. So food from the ocean should be labelled as coming from the aquatic systems. And there are aquaponics systems – perfecting soilless farming, and you can use freshwater and saltwater. The border between terrestrial and marine start to merge and get blurred. It’s a mental challenge about how we see these concepts. Nikos Zampoukas Commission DG TRD - working on developing research and policies in fisheries and aquaculture. Horizon 2020 has an action to put into use a blue growth farm project. Hope that all research efforts will go towards establishment of the Dutch multi-platform. See potential in use of seafood (even though it’s not a lot of biomass in the oceans); and of aquaculture (e.g. making trout vegetarian). Massive potential of bivalves and echinoderms to generate food. Reminder that natural food webs are efficient; it’s a wake-up call that we are asking too much from the sea. Discussion on the limits of marine food production will continue. We need solid knowledge on how marine foodwebs go. And we need to take into account policy issues, such as marine spatial planning, socio-economic aspects of seafood demand: EU framework programmes also work on this. Annette Hurrelmann Commission DG Mare - working on scientific advice and data collection. Notes references to agriculture. We need to come to a way of having and adopting a more holistic approach to food production – it’s not land versus sea; but to find a sustainable path to food production. Circularity and food systems approach and consequences for the planet. There are other users of the space. Oceans (and land) don’t just exist for our use, but there’s also nature to consider – and we start to understand that more and more and reflect on this in the policies: Farm to Fork, Green Deal etc; Paris Climate agreement. Multi-use of oceans means we need a more inclusive way of decision making on resource use. We need to think and act globally to solve the global challenges of food production. We can further improve efficiency of ocean food production, but to a limit, it’s not a big untapped potential; to be sustainable it’s not producing more, we also need to change our consumption patterns - reduce our intake of animal proteins. Sheila Hayman Executive Director of European Marine Board - an ecosystem modeller in previous life. Importance of looking at ocean not only for food, but also for human health, social well-being, and get new medicines from the ocean. Multi-trophic aquaculture - not everyone wants to eat mussels, there’s an education thing to be done to convince folk of these new things to eat. The N. Sea is a busy place – make sure you incorporate all users of the sea (NB: NIMBY). We need to make sure we don’t just look at biology, economy, ecology, but also the social sciences and how this influences folk in their jobs – we need a co- design. We can’t get more efficient with the food from the oceans, but we can make better use of what we catch and produce, and not throwing food away. Fishing industry and research create a lot of data and we have to make sure we use all this data and manage marine environment appropriately. Discussion DG Mare Ian Shepherd on pressure on the land: So, what can the sea do? Could you produce the same amount of protein at sea? There is potential. So, there’s a potential for shellfish production at the wind parks at sea.

  • SUSTAINABLE FISHERIES and RESPONSIBLE AQUACULTURE: a Guide for USAID Staff and Partners
    SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 ABOUT THIS GUIDE GOAL This guide provides basic information on how to design programs to reform capture fisheries (also referred to as “wild” fisheries) and aquaculture sectors to ensure sound and effective development, environmental sustainability, economic profitability, and social responsibility. To achieve these objectives, this document focuses on ways to reduce the threats to biodiversity and ecosystem productivity through improved governance and more integrated planning and management practices. In the face of food insecurity, global climate change, and increasing population pressures, it is imperative that development programs help to maintain ecosystem resilience and the multiple goods and services that ecosystems provide. Conserving biodiversity and ecosystem functions are central to maintaining ecosystem integrity, health, and productivity. The intent of the guide is not to suggest that fisheries and aquaculture are interchangeable: these sectors are unique although linked. The world cannot afford to neglect global fisheries and expect aquaculture to fill that void. Global food security will not be achievable without reversing the decline of fisheries, restoring fisheries productivity, and moving towards more environmentally friendly and responsible aquaculture. There is a need for reform in both fisheries and aquaculture to reduce their environmental and social impacts. USAID’s experience has shown that well-designed programs can reform capture fisheries management, reducing threats to biodiversity while leading to increased productivity, incomes, and livelihoods. Agency programs have focused on an ecosystem-based approach to management in conjunction with improved governance, secure tenure and access to resources, and the application of modern management practices.

  • What Is a Bottom Trawl?
    What is a Bottom Trawl? Bottom trawls are a type of mobile fishing gear consisting of very large nets that are dragged on the seafloor to catch groundfish and other species. Bottom trawls are used in virtually all East Coast, West Coast and Alaska fisheries to catch shrimp and fish such as cod, flounder and rockfish. Trawls are used from shallow, inshore depths of 50-feet to extreme depths of 6,000-feet on the continental slope. The National Academy of Sciences found in its 2002 report, “Effects of Trawling and Dredging on Seafloor Habitats,” that U.S. trawlers have damaged over 230,000 square nautical miles of seafloor, an area greater than California. The most common type of bottom trawl in the United States is the otter trawl, in which the net is held open vertically by the force of water moving against two massive otter doors/boards. The trawl net can stretch 40-feet in height and spread over 200 feet wide between the doors, depending on factors such as the depth fished and the type of fish targeted. A large, fully-rigged net weighs well over a ton and requires a large, powerful boat to drag the net, particularly when loaded with a catch of hundreds or thousands of pounds of fish and bycatch (unwanted, non-target species) in the codend, or back of the net. The impact to the seafloor from trawling is a compound of the weight of the net and the forward momentum of the gear as it is dragged forward. The opening of a bottom trawl net is lined with floats on the headrope and with weighted ground gear on the footrope.

  • The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition
    The Role of Sustainable Fisheries and Aquaculture for Food Security and Nutrition James Rohan CPA MBA WorldFish, FAO and World Resources Institute has conducted research recently which will support many of the questions suggested. Principles of sustainable business should be considered as the framework seeks to have minimal negative impact on the global or local environment, community, society, or economy,while achieving an industrious objective. Local environment will require an understanding of marine life and a model similar to planetary boundaries may promote education, research opportunities and continuous improvement principles. Many of the researchers have commented on the lack of research activity in this area and justifies the request by FSN for consideration. Rather than calories, I have proposed in the past a nutritional mass balance approach to recognise nutrition for health in food security. This would require consideration of yield and while some researchers have identified process capability, we should also explore product capability. Is nutrition compromised under stress or can it be enhanced with management? Over 90% of the world's living biomass is contained in the oceans, which cover 71% of the Earth's surface. At present, we harvest about 0.2% of marine production. ● Marine sources provide about 20% of the animal protein eaten by humans. Another 5% is provided indirectly via livestock fed with fish. ● 60% of fish consumption is by the developing world. ● The fishing enterprise employs some 200 million people worldwide. http://www.globalchange.umich.edu/globalchange2/current/lectures/fisheries/fisheries.html Data exists which suggests some fisheries are over and under exploited.

Box 140, 4401 NT Yerseke, The Netherlands 3Wageningen Marine Research, Wageningen University & Research, IJmuiden, The Netherlands Correspondence to : Emil De Borger ([email protected]) Abstract 10 Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through a mortality of the macrofauna, resuspension of organic matter from the sediment, and alterations of the physical sediment structure. However, the trawling impacts on organic carbon mineralization and associated processes are not well known. Using a modelling approach, the effects of increasing trawling frequencies on early diagenesis were studied in five different sedimentary environments, simulating the effects of a deep penetrating gear (e.g. a tickler chain beam trawl) and a 15 shallower, more variable penetrating gear (e.g. an electric pulse trawl). Trawling events strongly increased oxygen and nitrate concentrations in surface sediment layers, and led to significantly lower amounts of ammonium (43 – 99 % reduction) and organic carbon in the top 10 cm of the sediment (62 – 96 % reduction). As a result, total mineralization rates in the sediment were decreased by up to 28 %.

  • Ecosystem Approach to Fisheries Management (EAFM) Expands on Fisheries Management to Include Additional Ecosystem Considerations (Figure 1)
    Ecosystem Approach LME: LEARN to Fisheries Management POLICY BRIEF Managing fisheries and ecosystem interactions for social, economic and environmental benefits © Shutterstock/kittipong sirirattatanon Context and importance of the problem The majority of the world’s fisheries are over exploited with the ecosystems that sustain them becoming increasingly degraded. Maintaining productive and sustainable fisheries is essential to feeding the planet’s growing population while also supporting local livelihoods and commercial industries. The most productive and accessible regions of the world’s marine fisheries are Large Marine Ecosystems (LME) that join the land and the open ocean. Management of these expansive and diverse ecosystems and the fisheries they support requires effective cooperation between neighbouring and regional countries. Box 1: Principles of EAFM Fisheries should be managed to limit their impacts on the ecosystem to the extent possible taking in consideration the following: 1. Ecological relationships between harvested, dependent and associated species should be maintained 2. Management measures should be compatible across the entire distribution of the resources, which includes across jurisdictions and management plans 3. The precautionary approach should be applied because the knowledge on ecosystems is incomplete 4. Governance should ensure both human and ecosystem wellbeing and integrity (Garcia, 2003). © Shutterstock/pixinoo The Ecosystem Approach to Fisheries Management (EAFM) expands on fisheries management to include additional ecosystem considerations (Figure 1). This is proving successful at the LME scale when implemented through coordinated partnership between national bodies and managed at a regional-scale. The EAFM brings a more effective and holistic management approach to address the sustainability of fisheries, essentially focusing on the ecosystem rather than a particular target species.

The development of marine ranching requires integrating different theoretical frameworks, methodological approaches for conceptual exploring, and models and management of ecosystem frameworks. We reviewed the definition of marine ranching, the history of marine ranching construction in China, and the techniques, principles, and cases of marine ranching construction and management in the East China Sea (ECS). We highlight four major developments in marine ranching in the ECS: (1) marine ranching site selection and design, (2) habitat restoration and construction technologies, (3) stock enhancement and the behavioral control of fishery resources, and (4) marine ranching management. We conclude that this step-wise procedure for marine ranching construction and management could have comprehensive benefits in terms of ecology, the economy, and society. Finally, a synthesis of the existing problems in ECS marine ranching construction, along with future challenges and directions, are outlined.
