Abstract:
... Lice shielding skirts are a preventative measure against salmon lice in Atlantic salmon farming. The skirt is wrapped around the top meters of the net cage to divert the current flow around the cage, and thereby keep the salmon lice out. Despite these skirts being used actively in Norwegian aquaculture for the past decade, there is no standardised way of using them, and therefore type, depth and o ...

Abstract:
... A jeotgal-like product was processed from Chinook salmon (Oncorrhynchus tshawytscha) roe. Physicochemical, biochemical, and microbiological compositions were studied during 30 days of fermentation. Fermentation decreased water activity (aw) and pH value. Total bacterial and LAB counts (log CFU/g) increased up to 12 days of processing and then no further changes occurred. Saturated fatty acids (SFA ...
... Escolar or oilfish being sold as cod is a worldwide concerning food counterfeiting issue. This study established a simple and rapid real-time recombinase polymerase amplification (RPA) assay for oilfish (Ruvettus pretiosus) and escolar (Lepidocybium flavobrunneum) detection. The assay uses RPA primers and a probe designed for the intraspecific conserved and interspecific regions in the COI and Cyt ...

Abstract:
... Understanding the spatial and temporal habitat use of a population is a necessary step for recovery planning. For Chinook salmon (Oncorhynchus tshawytscha), variation in their migration and habitat use complicate predicting how restoring habitats could impact total recruitment. To evaluate how juvenile life history variation affects a population’s response to potential restoration, we developed a ...

Abstract:
... The design of enzymatic droplet-sized reactors constitutes an important challenge with many potential applications such as medical diagnostics, water purification, bioengineering, or food industry. Coacervates, which are all-aqueous droplets, afford a simple model for the investigation of enzymatic cascade reaction since the reactions occur in all-aqueous media, which preserve the enzymes integrit ...

Abstract:
... Growth hormone transgenic coho salmon experience increased growth rates, driven primarily through elevated feed intake and feed conversion. However, neuropeptides that signal appetite stimulation have been shown to exhibit variable responses across fed states, suggesting a more complex system mediating growth in these fish. Studies have proposed that growth hormone may have a modulatory role on th ...

Abstract:
... In this paper we present a suggestion for a sustainability assessment framework using genome editing of salmon as a case study. The salmon farming industry is facing several challenges hindering sustainable production. Genome editing has entered as a tool that can improve selective breeding and feed ingredients in aquaculture, hence providing solutions such as resistance to salmon lice and other p ...

Abstract:
... Carbon dioxide (CO₂) is an important gas used in modified atmosphere packaging of non-respiring foods where it solubilizes into the aqueous and lipid phases of food and exerts an antimicrobial effect. Prediction of CO2 solubility within food is thus of paramount importance to anticipate its benefit on food preservation. In the present study, machine learning algorithms were applied on a set of 362 ...

Abstract:
... Early maturation of Atlantic salmon male postsmolts is undesirable in aquaculture due to its negative impact on growth, welfare and seawater adaptation, however it is an increasing problem under intensive rearing conditions. The effect of temperature and feeding ration on sexual maturation during the induction of smoltification was tested with a 3 × 2 factorial design including three temperatures ...
... ISAV is the causative agent of the infectious salmon anaemia (ISA), a disease listed by the OIE that has caused important economic losses to the Atlantic salmon (Salmo salar) industry. ISAV variants are identified as pathogenic or non‐pathogenic based on the presence or absence of a deletion in the highly polymorphic region (HPR) of segment 6 (S6). HPRΔ variants (pathogenic) are the only forms of ...
... Infectious salmon anemia (ISA) can be devastating in farmed Atlantic salmon (Salmo salar). The disease can evolve into epidemics if it is not contained and controlled. ISA epidemics were seen in Norway in the early 1990s and Chile in 2007–2009. Consequently, there is an urgent need to develop a vaccine to prevent or treat the infection. In this study, an immunoinformatic approach was employed to p ...

Abstract:
... Accurate forecasts of sockeye salmon (Oncorhynchus nerka) in Bristol Bay, Alaska, play an important role in management and harvesting decisions for this culturally and ecologically vital species. We used a suite of parametric and nonparametric models to assess the frontiers in forecast accuracy of Bristol Bay sockeye salmon possible given currently available data. In retrospective performance test ...

Abstract:
... Sea lice infestations have been a major problem for the global salmon farming industry for several decades. To date, few studies have addressed the measurement of lice abundance in plankton samples and a standardized method to quantify sea lice larvae in water samples is still lacking. This study aims to: (1) evaluate the methods used to detect sea lice larvae based on published data and (2) to de ...

Abstract:
... Freshness prediction was a research hotspot in the field of food science. The current microbial kinetic equations could predict the freshness under certain fixed temperature conditions, but they were no longer effective when the temperature was fluctuated. To solve this problem, this paper used deep learning techniques to mine the inherent relation of variable temperature during storage and propos ...

Abstract:
... In chum salmon (Oncorhynchus keta) homed to the Sanriku region, Japan, most of the fish are matured in bays and spawn near river mouths in coastal short rivers; therefore, their upriver migration is extremely short, but their behavioural characteristics have remained unknown. Upriver migration in the Otsuchi River, a typical coastal river, was evaluated from behavioural and physiological aspects. ...

Abstract:
... While highly successful in terms of profitable seafood production, salmon (Salmo salar) aquaculture may also be a source of potential negative environmental externalities. In an attempt to address these challenges through supporting the development of new technology, the Norwegian government has introduced a new class of aquaculture licenses labeled as development licenses. As a result, new techno ...

Abstract:
... The past few decades have seen a turn to the empirical in applied ethics. This article makes two contributions to debates on this turn: one with regard to methodology and the other with regard to scope. First, it considers empirical bioethics, which arose out of a protest against abstract theorizing in moral philosophy and a call for more sensitivity to lived experience. Though by now an establish ...

Abstract:
... Salmon farming stands out from many other industries with its very high profitability, but it is also highly volatile. The main question is whether the profit of individual firms is stable, or whether profitable firms change from year to year. The purpose of this article is to apply the theory of profit persistence to answer this question for salmon farming in Norway. By using panel data from 2010 ...

Abstract:
... Rapid climate change is altering Arctic ecosystems and significantly affecting the livelihoods and cultural traditions of Arctic Indigenous peoples. In the Inuvialuit Settlement Region (ISR), growing evidence suggests that climate change is altering marine environments. In this project we recorded and synthesized Inuvialuit knowledge of Pacific salmon. We used methods that are emergent in fisherie ...

Abstract:
... The microsporidian Desmozoon lepeophtherii Freeman and Sommerville, 2009 is considered significant in the pathogenesis of gill disease in Atlantic salmon (Salmo salar Linnaeus, 1758). Due to the difficulty in detecting D. lepeophtherii in tissue sections, infections are normally diagnosed by molecular methods, routine haematoxylin and eosin (H&E) stained gill tissue sections and the use of other h ...
