uccinate is widely used in the food and feed industry as an acidulant, flavoring additive, and antimicrobial agent. This study investigated the effects of dietary succinate on growth, energy budget, nutritional metabolism, protein succinylation, and gut microbiota composition of zebrafish. Zebrafish were fed a control-check (0% succinate) or four succinate-supplemented diets (0.05, 0.10, 0.15, and ...

The growing interest in harvesting mesopelagic fish species has increased the need for knowledge about how trawls should be designed for optimizing the catch efficiency of these resources. Since the net herding efficiency for small mesopelagic fish species is unknown, trawls targeting these species need to consider the potential net panel selectivity along the entire trawl body. Therefore, trawl ...

Growing demands stimulate the intensification of production and create the need for practices that are both economically viable and environmentally sustainable. As European Union banned the use of antibiotics in production in 2003, several alternative treatments have been suggested, including probiotics. The first probiotic study in aquaculture was published in 1986, and since then probiotics ...

The aim of this study was to evaluate histologic post-mortem autolytic changes in farmed Atlantic salmon. The fish were either stored at room temperature (RT, 21°C), refrigerated (4°C) or frozen (−20°C), while fish necropsy was performed at 0, 1, 4, 24 and 48 h post-storage (hps). In addition, gills were sampled at 0, 5, 10, 15, 30 and 45 min post-storage (mps) at room temperature (RT). The haematoxylin ...

Aim: We assessed temporal trends in functional diversity of the deep-sea demersal fish communities of East Greenland to characterize ecological responses to rising sea temperatures.<p> <p>Location: The study region encompasses a shelf and slope area located offshore between 63°N and 66°N, east of Greenland. <p>Methods: A unique dataset of demersal fish abundance covering a depth range of 1500 m ...

Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity and regional governance frameworks. Arctic living marine resources are affected in various ways. A holistic understanding of these effects requires a multidisciplinary enterprise. ...

Previous studies have reported that cod caught using a newly developed dual sequential codend showed significant reduction in external catch-related damage compared to cod caught by a conventional codend. In this study, it was investigated whether this new codend affects residual blood in cod fillets and/or mitigates the effect of postponed bleeding. Residual blood was assessed by measuring ...

Europa står i en krisesituasjon, med den største strømmen av mennesker på flukt siden andre verdenskrig, og kvinner og barn betaler som vanlig en høy pris. Men krig har brakt ukrainske kvinner til Norge før.

Background: MyD88 directly interacts and affects IRF activation in mammals, but no information has been available about lower vertebrates.<p> <p>Results: Transgenic MyD88 interacts with IRF3 and IRF7A/B and modulates the IRF-induced IFN response and accumulates in aggresomes in Atlantic salmon. <p>Conclusion: MyD88 is involved in the regulation of the IRF-induced IFN response in Atlantic ...

Livslang læring er det nye mantraet. Det dukket opp som et slagord for utdanningsreform på 1970-tallet og er i dag noe som alle tilsynelatende er enige om. Men livslang læring har ulike betydninger og begrunnelser. Veien fra slagord til reform har også vært lang. Denne artikkelen gir et tilbakeblikk på den sammensatte bruken av begrepet og oppsummerer de viktigste reformene som har vært gjennomført ...
