“…Fredriksen and Sjøtun (2015) recommended using local ecotypes for crop breeding and restricting the produced crops within fjord systems and coastal areas defined by the eco-region based map catalogue from the Norwegian Environ ment Agency (Miljødirektoratet, https://kartkatalog.miljodirektoratet.no/Dataset/Details/501). Sterilization technologies for cultivated seaweeds have also been suggested as a measure to mitigate gene swamping (Loureiro et al 2015), but examples of supposedly sterile aquaculture organisms adapting over time and eventually being able to reproduce after all (Jouaux et al 2010) advise caution in such cases.…”

The use of cultivated seaweeds as a feedstock for multiple industrial applications has gained increasing interest in the Western World over the past decades. Norway has an extensive coastline and a well-established aquaculture sector offering suitable preconditions for developing large-scale cultivation of seaweed biomass both in monoculture and in Integrated Multi-Trophic Aquaculture (IMTA) systems. Recent efforts from research, industry and public authorities have been committed to develop a Norwegian bio-economy based on cultivated seaweed, focusing on cultivation and processing of the biomass. This review reports on the status of seaweed aquaculture in Norway, supported by production data collected since the delivery of the first commercial cultivation permits at sea in 2014. Although novel product developments are currently limited, future industrial perspectives based on cultivated biomass are being discussed. Upscaling from experimental cultivation schemes to commercial production requires a thorough assessment of the risks and benefits associated with seaweed aquaculture, as well as the development of a regulative framework adapted to this industry. Issues associated with upscaling the macroalgal production that needs to be addressed includes (i) genetic interactions between cultivated and wild crops, (ii) impacts of seaweed cultivation on surrounding ecosystems, (iii) epiphytes and diseases, (iv) area utilization and (v) threats from climate change. Addressing these issues and adapting production practices will ensure the environmental and economic sustainability of an emerging industry based on cultivated seaweed biomass in Norway.

“…After their own independent evolution for more than 200 million years (Silberfeld et al 2010), the current brown algal group consists of a multitude of taxa including 19 orders, 62 families, 473 genera, and more than 2000 species with various morphological and physiological characteristics (Charrier et al 2012;Liu and Pang 2015b). Brown algae are one of the major photosynthetic producers of organic carbon on rocky intertidal shores of the world and play an important role both as human food and for the habitats that they form (Loureiro et al 2015).…”

Sargassum horneri (Turner) C. Agardh is an important canopy-forming seaweed native to the northwestern Pacific coast growing in the upper sublittoral zone. In this study, the chloroplast genome of S. horneri was fully sequenced and compared with three other brown algal chloroplast genomes. The S. horneri chloroplast genome is 124,068 bp in size with an inverted repeat of 5436 bp and is slightly smaller than the other three brown algal chloroplast DNAs (cpDNAs). It contains 173 genes, including 6 ribosomal RNA (rRNA) genes, 28 transfer RNA (tRNA) genes, and 139 protein-coding genes (PCGs). The coding sequence constitutes 86.32 % of the S. horneri cpDNA. The total spacer size was found to be reduced to 16,967 bp with an average length of 101.0 bp, which makes the S. horneri cpDNA more compact than the other three brown algal cpDNAs. Sixteen small inverted and nine tandem repeats were detected in S. horneri chloroplast genomes. Two introns in trnL2 and trnW genes were identified with the size of 209 and 90 bp, respectively. Its gene content and order are identical to those of Fucus vesiculosus cpDNA, indicating that the chloroplast genome organization at the level of the order Fucales is highly conserved.

“…A significant number of these studies can be found within Food and Agriculture Organisation reports including Food and Agriculture Organisation (FAO) (2006) and numerous industry investigations into using seaweed dating to as early as the 1970s [14]. Indeed, over 23 million dry tons of macro-algae were produced by aquaculture in 2012, mostly for human consumption [24]. For biofuel stakeholders and policy makers to fully understand the issues related to developing a seaweed biofuel industry, it is necessary to provide an in-depth and robust review of the seaweed literature beyond technological aspects.…”

UK Macro-Algae Biofuels: A Strategic Management Review and Future Research Agenda

Macro-algae is increasingly gaining attention as a potential feedstock for biofuels and as a potential alternative fuel for aviation. Technological aspects are showing promise, and being examined more widely. This paper uses a strategic management perspective to complete an initial macro-environmental scan of the potential opportunities and threats to a seaweed biofuels industry. This is in response to calls to look beyond technological aspects, and highlights the importance of social acceptance. It is clear that very little is known about the potential economic, social, environmental and political/legal issues that might arise in the development of this industry. While we can look at the development of other, more established renewable technologies and seaweed industries away from the UK to highlight potential issues this does not give us a clear picture. Further research is needed to ensure that a proactive approach is used to research and inform stakeholders who will affect the further technological development and commercialization of the industry.
