& In recent years there has been increased interest in the transaction forms in salmon markets, given that contracts have become more common, vertical mergers create firms that cover several levels in the supply chain, and futures markets have developed as a price risk tool. These are strong indications that salmon supply chains are developing in the same direction as supply chains for more processed food products. In this article we investigate to what extent this development has influenced the price transmission process for two product forms: a relatively unprocessed one (fresh fillets) and a more processed one (smoked salmon). Results indicate that the supply chain for fresh fillets can still be characterized by a high degree of price transmission. On the contrary, the hypothesis of full price transmission for smoked salmon is rejected.

“…Higher summer sea surface temperatures may be problematic for farmed species that are adapted for life in cold water. As a result, the productivity of aquaculture species can be affected, and Southern Norway may be less suitable for species such as salmon, with socio-economic impacts (Hermansen and Heen 2012). Such climatic changes may eventually entail that northern areas will be better suited for mariculture than southern regions (Bergh et al 2007).…”

Seaweed aquaculture in Norway: recent industrial developments and future perspectives

2017

View full text Add to dashboard Cite

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.

“…To date, the more technical investigation of economic impacts of climate change on aquaculture has involved intensive modelling exercises of Norwegian salmon farming or more general investigations of effects for aquaculture in the Tropical Pacific region. Lorentzen (2008) analysed the effect of more volatile sea surface temperature on the economics of salmon farming in Norway, while Hermansen & Heen (2012) considered the impact of temperature changes on the spatial distribution of production and employment. One result is the shift of production further north in response to increasing temperatures, with potential effects on production and transportation costs.…”

The heavy reliance of most global aquaculture on the ambient environment suggests inherent vulnerability to climate change effects. This review explores the potential effects of climate change stressors on aquaculture biology and resources needed to support decision-making for vulnerability assessment, planned adaptation, and strategic research development. Climate change-mediated physiochemical outcomes important to aquaculture include extreme weather, precipitation and surge-based flooding, water stress, ocean acidification, sea-level rise, saltwater intrusion, and changes to temperature, salinity, and dissolved oxygen. Culture practices, environment, and region affect stressor exposure, and biological response between species or populations are not universal. Response to a climate change stressor will be a function of where changes occur relative to optimal ranges and tolerance limits of an organism's life stage and physiological processes; the average magnitude of the stressor over the production cycle; stressor rate of change; variation, frequency, duration, and magnitude of extremes; epigenetic expression, genetic strain, and variation within and between populations; health and nutrition; and simultaneous stressor occurrence. The effects of simultaneous stressors will frequently interact, but may not be fully additive or synergistic. Disease is a major aquaculture limiter, and climate change is expected to further affect plant and animal health through the host and/or infectious agents. Climate change may introduce further complexity to the aquaculture−wild fishery relationship, with over two-thirds of animal aquaculture production dependent on external feed inputs. Higher production costs could be an economic outcome of climate change for many aquaculture sectors. Some aquaculture practices may inadvertently reduce resiliency to climate change, such as a reduction of coastal vegetation, coastal ground-water pumping, and reduction of population variability in pursuit of consistent production traits. Information from the largest aquaculture producers such as China and the top 3 global culture species is still sparse in the literature. This potentially limits thorough understanding of climate change effects on some regional aquaculture sectors.
