Bij elke levenscyclusanalyse komt het voer naar voren als de meestmilieubelastende component van de aquacultuursector. Een van de oorzaken daarvan is het gebruik van eiwitbronnen. Plantaardige ingrediënten vragen land, water en energie, en de vangst van vis voor vismeel en visolie is energieintensief en draagt bij aan de verstoring van de biodiversiteit in zee. In een NWO-KIEM project vanuit het lectoraat INVIS inventariseerden onderzoekers, samen met studenten van de HAS Hogeschool, de kansen en uitdagingen van het gebruik van meel van insecten die groeien op afval. De kennis die is opgedaan tijdens het eenjarige project is gedeeld met geïnteresseerden tijdens een webinar.

As the first order of business in the RIGHT project, each region produced and published its own regional report, using an underlying format developed in work package 3 in this project (Manickam & van Lieshout, 2018). The format and the regional work consisted of three parts. Part 1 is the Regional Innovation Ecosystems (RIE) mapping to provide a qualitative understanding of the region’s innovation ecosystem with regards to its Smart Specialisation Strategies (S3). This part is divided into a socio-economic and R&D profile mapping and a SWOT analysis. The RIE is an adaptation of a methodology and tool used by the eDIGIREGION Project. This part is to be filled in by desk research and consulting regional experts (through interviews and/or focus groups). This part is used for mapping the own regional ecosystems, information for the partners to get to know the other regions and to be able to identify relevant similarities and differences across the regions, which in turn, will be reported in part 1 of this trans-regional report. Regions themselves chose their own sector focus. One could focus on either energy of the blue sector, or both. Part 2 focuses on the innovation capacity and needs of SMEs from the chosen sector(s). The questions are adapted from a systemic study on cluster developments, in which an analysis model was developed (Manickam, 2018). It is based on (on average) six face-to-face interviews with SMEs from the sector. The outputs of these interviews were summarised into one template, in English, by each partner region to allow for joint analysis and comparison that is in turn reported in part 2 of this report Part 3 introduced the Job Forecasting and Skills Gaps mapping using the JOES templates as developed by van Lieshout et al. (2017). To gain an appreciation of the extent and nature of skills gap, each region was asked to analyse current and potential future labour demand, workforce, and discrepancies between the two, in up to 2 businesses. For obvious reasons (confidentiality and privacy), the JOEs will not be published separately, nor will their information be used in the report in a way that would be traceable to specific businesses. We will use exemplary information from them for illustrative purposes in Parts 1 and 2 of this report where relevant.

Seaweeds from the genus Porphyra play a big economic role in seaweed aquaculture, mainly in Asia. In Europe, resources are put towards seaweed cultivation, but without attention to the Porphyra species which is also native to Europe. Different nomenclature and specifications are used to describe Porphyra, due to taxonomical reclassification and difficult phenotypical identification. Abiotic & biotic together with seasonal factors make for major variance in chemical compositions that are reported. This is also fueled by differences in chemical analytical methods and procedures followed. Combining taxonomical challenges, variance due to seasonal factors and differences in analysis, overviewing published research on Porphyra constituents such as protein, polysaccharides and fatty acids is warranted. Within this review, cellular consitutents found in Porphyra are discussed, including proteins, polysaccharides, fatty acids and mycosporine-like amino acids (MAA’s). MAA's are considered amongst the strongest UV-photoprotectants found in nature and feature possible applications in cosmetics. As global interest in seaweeds as food, feed and industrial resource is emerging, opportunities for Porphyra constituents is rising.
Onze huidige voedselvoorziening wordt gekenmerkt door overmatig gebruik van bestrijdingsmiddelen zoals antibiotica, genetische manipulatie, overdadig veel transport, water en andere grondstoffen worden gebruikt en productieprocessen gebaseerd op fossiele brandstoffen. Ook wordt veel landbouwgrond dusdanig uitgeput dat de kwaliteit van de grond en de diversiteit sterk achteruit gaan. Gezonde en duurzaam geproduceerde voeding zou voor iedereen bereikbaar moeten zijn. Bovendien is er veel leegstand in verschillende regio’s, deze leegstand kan door middel van aquacultuur systemen zeer waardevol worden benut. Dit is de aanleiding geweest om te zoeken naar alternatieve mogelijkheden voor duurzame productie van voedsel binnen de agrifoodsector. Geïntegreerde aquacultuur systemen worden verwacht goed toepasbaar te zijn voor duurzame voedingsproductie. Deze systemen verminderen de afhankelijkheid van de huidige voedselvoorziening van chemie, olie en gas. Bovendien stimuleert het de lokale en regionale economie en schept het duurzame werkgelegenheid. De doelstelling is het sluiten van de materiaalstroomketen, het voorkomen van afvalstoffen en het stimuleren van grondstof besparing. De aanpak van dit project is daarom gericht op de transitie naar circulaire materiaalstromen waarbij hoogwaardig hergebruik van de materialen mogelijk is op een manier waarbij waarde wordt toegevoegd. Hierbij worden mogelijkheden verkent in het kader van de biobased economy en nieuwe business- en verdienmodellen van dergelijke geïntegreerde aquaculturen. De onderzoeksvraag voor A2FISH is welke circulaire business- en verdienmodellen er realiseerbaar zijn voor kansrijke geïntegreerde aquacultuursystemen binnen de agrifoodsector. Om die onderzoeksvraag uiteindelijk te kunnen beantwoorden, zijn een aantal deelvragen geformuleerd: • Welke aquacultuursystemen zijn kansrijk toepasbaar binnen de agrifoodsector? • Aan welke technische en economische aspecten moet een aquacultuursysteem voldoen om te komen tot kansrijke business- en verdienmodellen? • Welke soorten planten kunnen worden met waardevolle inhoudsstoffen kunnen worden gekweekt met de aquacultuursystemen? • Welke soorten gangbaar industrieel visvoer kan worden gefabriceerd uit reststromen uit de voedingsmiddelenindustrie en welke invloed heeft dit voer als bemesting op de waterkwaliteit? • Hoe ziet een vervolgtraject voor een geïntegreerd circulair aquacultuursysteem eruit en in hoeverre is dit anders dan voor gangbare alternatieven?
The seaweed aquaculture sector, aimed at cultivation of macroalgal biomass to be converted into commercial applications, can be placed within a sustainable and circular economy framework. This bio-based sector has the potential to aid the European Union meet multiple EU Bioeconomy Strategy, EU Green Deal and Blue Growth Strategy objectives. Seaweeds play a crucial ecological role within the marine environment and provide several ecosystem services, from the take up of excess nutrients from surrounding seawater to oxygen production and potentially carbon sequestration. Sea lettuce, Ulva spp., is a green seaweed, growing wild in the Atlantic Ocean and North Sea. Sea lettuce has a high nutritional value and is a promising source for food, animal feed, cosmetics and more. Sea lettuce, when produced in controlled conditions like aquaculture, can supplement our diet with healthy and safe proteins, fibres and vitamins. However, at this moment, Sea lettuce is hardly exploited as resource because of its unfamiliarity but also lack of knowledge about its growth cycle, its interaction with microbiota and eventually, possible applications. Even, it is unknown which Ulva species are available for aquaculture (algaculture) and how these species can contribute to a sustainable aquaculture biomass production. The AQULVA project aims to investigate which Ulva species are available in the North Sea and Wadden Sea which can be utilised in onshore aquaculture production. Modern genomic, microbiomic and metabolomic profiling techniques alongside ecophysiological production research must reveal suitable Ulva selections with high nutritional value for sustainable onshore biomass production. Selected Ulva spp lines will be used for production of healthy and safe foods, anti-aging cosmetics and added value animal feed supplements for dairy farming. This applied research is in cooperation with a network of SME’s, Research Institutes and Universities of Applied Science and is liaised with EU initiatives like the EU-COST action “SeaWheat”.
Sea Lettuce, Ulva spp. is a versatile and edible green seaweed. Ulva spp is high in protein, carbohydrates and lipids (respectively 7%-33%; 33%-62% and 1%-3% on dry weight base [1, 2]) but variation in these components is high. Ulva has the potential to produce up to 45 tons DM/ha/year but 15 tons DM/ha/year is more realistic.[3, 4] This makes Ulva a possible valuable resource for food and other applications. Sea Lettuce is either harvested wild or cultivated in onshore land based aquaculture systems. Ulva onshore aquaculture is at present implemented only on a few locations in Europe on commercial scale because of limited knowledge about Ulva biology and its optimal cultivation systems but also because of its unfamiliarity to businesses and consumers. The objective of this project is to improve Ulva onshore aquaculture by selecting Ulva seed material, optimizing growth and biomass production by applying ecophysiological strategies for nutrient, temperature, microbiome and light management, by optimizing pond systems eg. attached versus free floating production and eventually protoype product development for feed, food and cosmetics.
