Summary: The recent work of Mariana Mazzucato sheds light on the role of public funding in economic development, particularly in the case of the Chilean salmon industry. The paper argues that the Chilean salmon industry's innovation system should be understood within a neostructural model of economic development. While the State has played a crucial role in financing and promoting innovation, it has not provided guidance on how innovation should be carried out.

Summary: The study highlights the inconsistency in defining "offshore" aquaculture and the perception among stakeholders in Scotland regarding the key characteristics of offshore environments. While some stakeholders consider wave exposure as the main feature, existing regulations are deemed inadequate for offshore salmon production. This emphasizes the need for a consistent terminology and potential modifications to regulations in order to support offshore aquaculture development.

Summary: This study examines the role of certification and sustainable seafood ranking programs in maintaining ecosystem services and supporting EAA, finding that while a range of ecosystem services are reflected in sustainability scheme criteria, attributes supporting resilience capacity, enhancement of ecosystem services, and cost-benefit analysis for salmon farming are limited.

Summary: This study investigates the dynamics of microbial communities in a recirculating aquaculture system (RAS) over a 20-month period. The results show that the production batches, disinfection processes, and flow rate can influence the composition and dynamics of the water microbiota. UV treatment can efficiently reduce bacterial density without compromising the water quality.

Summary: Anemia in salmonid aquaculture is a recognized blood disorder caused by the reduction of hemoglobin concentration and/or erythrocyte count. This health issue negatively affects fish growth and health due to sub-optimal oxygen supply to tissues, and can be linked to factors such as environmental changes, infectious agents, nutritional deficiencies, or hemorrhaging. The recent cases in Scottish salmon farming industry show the need for better understanding of anemia pathogenesis and development of effective mitigation strategies.

Summary: The Norwegian aquaculture industry is under pressure to ensure sustainable production, with ASC certification providing a tool for enhancing reputation and sustainability. Motivations for certification include preparing for future market demands, even though it may not guarantee immediate financial benefits. The industry values the potential reputational gain from certification.

Summary: The ecosystem approach to aquaculture (EAA) is a strategy for sustainable development, with a focus on environmental impact indicators. Research in salmon aquaculture literature primarily revolves around near-field benthic impact indicators. When evaluating indicators, scalability and alignment with environmental indicator criteria are essential considerations.

Summary: The AcuLice system, which uses a composite acoustic sound image, has been shown to effectively reduce the number of salmon lice on Atlantic salmon without causing additional stress to the fish.

Summary: The microbiota of recirculating aquaculture systems (RAS) is crucial for fish health, but more knowledge is needed to control and maintain beneficial microbial communities. This study analyzed the microbial communities in a commercial RAS producing Atlantic salmon fry to understand their dynamics and potential control mechanisms.

Summary: This article examines the effects of captive offshoring on firm innovation, specifically distinguishing between the effects on innovation generation and market diffusion. By integrating insights from the innovation diffusion literature, the study finds that captive offshoring has an inverted u-shape effect on innovation propensity in the home base, with positive effects for the average firm. However, employment offshoring does not, on average, affect the rate of diffusion as measured by the share of turnover from new products. For firms with more novel product innovations, the effects are even negative.

Summary: France is the second largest importer of salmon in Europe, and media coverage of farmed salmon in France focuses on topics related to economy, health, and environment. Compared to other countries, the French media pays more attention to health issues, with most articles about farmed salmon being negative, potentially jeopardizing the reputation of salmon as a healthy food. The negative framing of Norwegian salmon and the industry in French media could negatively impact consumer behavior towards Norwegian salmon.

Summary: The high infestation of salmon louse raises concerns about the sustainability of the Norwegian Atlantic salmon aquaculture industry. The connectivity of infective pelagic lice stages among farms plays a vital role in louse population dynamics, but the processes regulating this connectivity are not well understood. A biophysical dispersal model using ocean currents was employed to study the connectivity network among salmon farms in western Norway, showing that the complex geography of the fjords governs the long-term topology of the network, but there is also a strong seasonal component to network fragmentation.

Summary: Global aquaculture production has experienced rapid growth in recent decades, largely due to innovative advancements in production processes and competitiveness. However, there is a lack of studies examining the long-term impacts of these innovations on the aquaculture industry and the innovation system as a whole. This paper reviews the innovation process in the Norwegian salmon aquaculture industry since its inception in 1970, with a focus on the increasing industry complexity and the role of suppliers in driving innovation. These insights are relevant to the global aquaculture industry, as salmon is one of the most technologically advanced species, and innovations in this sector can be adapted for other species and different production systems as well.

Summary: Simultaneous microbial community profiling and pathogen detection were conducted in a rainbow trout aquaculture facility. The study found fish pathogens in multiple locations and observed differences in community composition based on surface types. The results provide insights into the microbial communities and pathogen distribution in aquaculture facilities.
