“…Similar trends have been noted (albeit piecemeal) in the Norwegian salmon farming industry where expansion of production has been at tributed to control of the biological production process, improved fish performance and culture systems, and economies of scale that have in creased efficiency and reduced production costs (Bergheim and Brinker, 2003;Bergheim et al, 2009;Forster, 2010;Bergheim, 2012;Kristensen et al, 2012;Asche and Roll, 2013;Asche et al, 2013a,b;Shepherd and Little, 2014).…”

“…Disease has also been noted to affect ova supplies and employment. The importance of diseases to the salmon farming industries in Norway and Chile has been highlighted (Tilseth et al, 1991;Asche et al, 2009;Forster, 2010;Asche and Bjørndal, 2011;Asche and Roll, 2013) and FAO (2012) note the common importance of disease to aquaculture. Effective disease management -via reduced stress in stocks, vaccination, fallowing, area management agreements, biosecurity etc.…”

Trends during development of Scottish salmon farming: An example of sustainable intensification?

Commercial farming of Atlantic salmon in Scotland started in 1969 and has since expanded to produce N 179,000 t year −1 . A government department has published annual statistics and information on the seawater and freshwater sub-sectors of the Scottish salmon farming industry since 1979, and this review collates and dis cusses metrics covering aspects of production, farm sites and systems, fish performance, socio-economics and en vironmental pressures. Trends illustrated in this case study of aquaculture development include: initial increases in numbers of farms and companies, followed by decreases due to industry consolidation; increases in average farm size, and productivity of systems and employees; increases in survival, size at age and productivity of fish (yield per smolt, ova per broodstock); reduced dependence on wild stocks for ova. This case study also illustrates the importance of disease management, control of biological processes to overcome natural seasonality (i.e. pro duction of out-of-season smolt), and the international nature of aquaculture. Improvements in fish survival, growth and productivity are attributed to progress in vaccination and health management (including fallowing), husbandry, system design, feed formulation and provision, and introduction of technology and mechanisation. Salmon farming is discussed in relation to the challenging strategy of "sustainable intensification". Improved growth and survival over a period of increasing rearing unit size, farm size and output and decreasing relative staff input counters the common assumption that intensification compromises animal welfare. The value of cap turing time series data on industry wide metrics is illustrated as it enables identification of trends, underperformance and bench-marking, as well as assessment of resource use efficiency, environmental pres sures, and ultimately sustainability. Statement of relevance: This review is an original collation of a comprehensive set of time series of official statistics on an entire, discrete and regionally important sector of commercial aquaculture.Crown

“…Though about 97% of the world salmon production is currently based on improved stock (Gjedrem & Baranski, 2009), the salmon industry has been maintaining a strong research and development effort. There has been improvement in technical efficiency over time in the Norwegian salmon industry, mainly through restructuring the industry as well as making improvements in government regulations (Asche & Roll, 2013). It is projected that China will continue to be by far the largest aquaculture producing country.…”

& Seafood sector can contribute to the global food supply in an important way, and provide an important source of animal protein. Based on observed regional trends in seafood production and consumption and using a global, partial-equilibrium, multi-market model, this study investigates what the global seafood market may look like in 2030. The model projects that the total fish supply will increase from 154 million tons in 2011 to 186 million tons in 2030, with aquaculture entirely responsible for the increase. The fastest aquaculture growth is expected for tilapia and shrimp, while the largest expansion is expected in India, Latin America and Caribbean and Southeast Asia. Fast-growing seafood demand in China and elsewhere represents a critical opportunity for global fisheries and aquaculture to improve their management and achieve sustainable seafood economy.

“…It is well known that increases in productivity were initially the most important factor fueling this growth (Asche, 1997). A number of studies have provided insights with respect to the sources for this productivity growth; recent examples include Tveteras and Batteese (2006), Andersen et al (2008), Asche et al (2009b), Nilsen (2010), Aasheim et al (2011), Vassdal and Holst (2011), and Asche and Roll (2013). However, productivity growth has slowed down during the last decade (Vassdal & Holst, 2011), and demand growth has been as important as productivity growth to explain production increases in salmon aquaculture since the late 1990s (Asche et al, 2011a).…”

& 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.
