  • Increasing catch efficiency for Nephrops in deep-water shrimp (Pandalus borealis) trawl fisheries 

    Ingólfsson, Ólafur Arnar; Jørgensen, Terje; Sistiaga, Manu; Herrmann, Bent; Kvalvik, Liz Beate Kolstad (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-14)
    In Skagerrak and the North Sea, coastal vessels harvest deep-water shrimp (Pandalus borealis) in a mixed fishery, in which catches of Nephrops (Nephrops norvegicus) are of economic importance for the fleet. Fishermen targeting shrimp in this area must use a sorting grid with a maximum bar spacing of 19 mm, which means that only the smallest Nephrops can pass through the grid to be retained in the ...

  • The fate of conventional and potentially degradable gillnets in a seawater-sediment system 

    Brakstad, Odd Gunnar; Sørensen, Lisbet; Hakvåg, Sigrid; Føre, Heidi Moe; Su, Biao; Aas, Marianne; Ribicic, Deni; Grimaldo, Eduardo (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-20)
    Abandoned gillnets in the marine environment represent a global environmental risk due to the ghost fishing caused by the nets. Degradation of conventional nylon gillnets was compared to that of nets made of poly- butylene succinate co-adipate-co-terephthalate (PBSAT) that are designed to degrade more readily in the envi- ronment. Gillnet filaments were incubated in microcosms of natural seawater ...
  • Infectious salmon anemia virus (ISAV) replication is transiently inhibited by Atlantic salmon type I interferon in cell culture 

    Svingerud, Tina; Holand, Jenni; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-08-20)
    Infectious salmon anemia virus (ISAV) is a piscine orthomyxovirus, which causes multisystemic disease in farmed Atlantic salmon that may result in large losses. Previous work has suggested that ISAV is able to resist the antiviral state induced in cells by type I interferon (IFN). These studies were, however, mainly based on cytopathic effect (CPE) reduction assays. Here we have investigated the ...
  • Progress in fish gastrointestinal microbiota research 

    Wang, An R; Ran, Chao; Ringø, Einar; Zhou, Zhigang (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-02)
    The gastrointestinal (GI) microbiota of vertebrates plays critical roles in nutrition, development, immunity and resistance against invasive pathogens. In the past decade, research of the GI microbiota of mammals has drastically increased our knowledge on the microbiota and their relationship with health and disease. However, our understanding of fish intestinal microbiota is limited. This ...
  • The teleost polymeric Ig receptor counterpart in ballan wrasse (Labrus bergylta) differs from pIgR in higher vertebrates 

    Etayo, Angela; Bjørgen, Håvard; Koppang, Erling Olaf; Hordvik, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-13)
    As mucosal barriers in fish are the main sites where pathogens are encountered, mucosal immunity is crucial to avoid infection in the aquatic environment. In teleost fish, immunoglobulins are present in gut, gill and skin mucus, although not in the same amounts as in higher vertebrates. In mammals, the poly-Ig receptor (pIgR) is synthesized in epithelial cells and mediates the active transport ...
  • Protection of Atlantic salmon against virus infection by intramuscular injection of IFNc expression plasmid 

    Chang, Chia Jung; Robertsen, Camilla; Sun, Baojian; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-07-02)
    n this work we have tested the in vivo antiviral activity of type I interferons (IFNs) in Atlantic salmon by injecting presmolts intramuscularly (i.m.) with plasmids encoding IFNa1, IFNb or IFNc under the control of a CMV promoter, and measured expression of antiviral genes in organs and protection against infection with infectious salmon anemia virus (ISAV)infection. Allthree IFN plasmids induced ...

    Javed, Rana Tallal; Nasir, Osama; Vanhée, Loïs; Borit, Melania; Zea, Elias; Gupta, Shivam; Vinuesa, Ricardo; Qadir, Junaid (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-26)
    The domain of Artificial Intelligence (AI) ethics is not new, with discussions going back at least 40 years. Teaching the principles and requirements of ethical AI to students is considered an essential part of this domain, with an increasing number of technical AI courses taught at several higher-education institutions around the globe including content related to ethics. By using Latent Dirichlet ...
  • Monitoring bacterial community dynamics in a drinking water treatment plant: an integrative approach using metabarcoding and microbial indicators in large water volumes 

    Pinar-Méndez, Anna; Wangensteen, Owen S.; Præbel, Kim; Galofré, Belén; Méndez, Javier; Blanch, Anicet R.; García-Aljaro, Cristina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-30)
    Monitoring bacterial communities in a drinking water treatment plant (DWTP) may help to understand their regular operations. Bacterial community dynamics in an advanced full-scale DWTP were analyzed by 16S rRNA metabarcoding, and microbial water quality indicators were determined at nine different stages of potabilization: river water and groundwater intake, decantation, sand filtration, ozonization, ...
  • For all audiences: Incorporating immature stages into standardised spider inventories has a major impact on the assessment of biodiversity patterns 

    Domènech, Marc; Wangensteen, Owen S.; Enguídanos, Alba; Malumbres-Olarte, Jagoba; Arnedo, Miquel A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-25)
    Although arthropods are the largest component of animal diversity, they are traditionally underrepresented in biological inventories and monitoring programmes. However, no biodiversity assessment can be considered informative without including them. Arthropod immature stages are often discarded during sorting, despite frequently representing more than half of the collected individuals. To date, ...
  • Oceanic plastic pollution caused by Danish seine fishing in Norway 

    Syversen, Tore; Lilleng, Grethe; Vollstad, Jørgen; Bård, Hanssen; Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-06)
    Wear and tear on fishing gear is a sparsely investigated source of microplastic pollution in the sea. In Norway, Danish seine ropes and trawls are the fishing gears that contribute most to this pollution. The main reason for this pollution is that the seine ropes are dragged along the seabed over a considerable distance, creating a friction force that results in high ropes wear. This note reports ...
  • Growth performance, hepatic enzymes, and gut health status of common carp (Cyprinus carpio) in response to dietary Cetobacterium somerae fermentation product 

    Xie, Mingxu; Hao, Qiang; Olsen, Rolf Erik; Ringø, Einar; Yang, Yalin; Zhang, Zhen; Ran, Chao; Zhou, Zhigang (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-15)
    Intensive aquaculture practices compromise the health of fish. Probiotics especially those isolated from aquatic animals play important roles in improving fish health. The aim of the study was to evaluate the effects of stabilized fermentation product of Cetobacterium somerae (XMX-1) on the growth performance, gut and liver health of common carp. A total of 300 carps (initial weight of 2.32 ± 0.02 ...
  • Fish Skin and Gill Mucus: A Source of Metabolites for Non-Invasive Health Monitoring and Research 

    Ivanova, Lada; Rangel-Huerta, Oscar Daniel; Tartor, Haitham; Gjessing, Mona Cecilie; Dahle, Maria; Uhlig, Silvio (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-31)
    Mucous membranes such as the gill and skin mucosa in fish protect them against a multitude of environmental factors. At the same time, changes in the molecular composition of mucus may provide valuable information about the interaction of the fish with their environment, as well as their health and welfare. In this study, the metabolite profiles of the plasma, skin and gill mucus of freshwater ...

    Gordon, Timothy A.C.; Harding, Harry R.; Clever, Friederike K.; Davidson, Isla Keesje; Davison, William; Montgomery, Daniel W.; Weatherhead, Rebekah C.; Windsor, Fredric M.; Armstrong, John D.; Bardonnet, Agnès; Bergman, Eva; Britton, John Robert; Côté, Isabelle M.; D'agostino, Daniele; Greenberg, Larry; Harborne, Alastair R.; Kahilainen, Kimmo Kalevi; Metcalfe, Neil B.; Mills, Suzanne C.; Milner, Nigel J.; Mittermayer, Felix H.; Montorio, Lucie; Nedelec, Sophie L.; Prokkola, Jenni M.; Rutterford, Louise A.; Salvanes, Anne Gro Vea; Simpson, Stephen D.; Vainikka, Anssi; Pinnegar, John Keith; Santos, Eduarda M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-14)
    Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, energy and goods are compromising fish populations through a variety of mechanisms, including overfishing, habitat degradation and declines in water quality. The important ...
  • Effect of dietary components on the gut microbiota of aquatic animals. A never-ending story? 

    Ringø, Einar; Zhou, Zhigang; Vecino, Jose L. González; Wadsworth, Simon L.; Romero, Jaime; Krogdahl, Åshild; Olsen, Rolf Erik; Dimitroglou, Arkadios; Foey, Andrew David; Davies, Simon; Owen, Matthew A.G.; Lauzon, Hélène Liette; Martinsen, Lisbeth Løvmo; De Schryver, Peter; Bossier, Peter; Sperstad, Sigmund; Merrifield, Daniel Lee (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-07)
    It is well known that healthy gut microbiota is essential to promote host health and well-being. The intestinal microbiota of endothermic animals as well as fish are classified as autochthonous or indigenous, when they are able to colonize the host’s epithelial surface or are associated with the microvilli, or as allochthonous or transient (associated with digesta or are present in the lumen). ...
  • RAT-RS: a reporting standard for improving the documentation of data use in agent-based modelling 

    Achter, Sebastian; Borit, Melania; Chattoe-Brown, Edmund; Siebers, Peer-Olaf (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-30)
    This article describes and justifies a reporting standard to improve data use documentation in Agent-Based Modelling. Following the development of reporting standards for models themselves, empirical modelling has now developed to the point where these standards need to take equally effective account of data use (which previously has tended to be an afterthought to model description). It is ...
  • The impact of fisheries management on fishers' health and safety: A case study from Norway 

    Sønvisen, Signe Annie; Thorvaldsen, Trine; Holmen, Ingunn Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-18)
    Since the late 1980s, Norwegian fishers have been subjected to a cohesive regulatory regime aimed at sustainable resource management. Despite high occupational injury rates and exposure to several factors that may influence health negatively, regulation of occupational health and safety (OHS) came late in fishing compared with other industries. Fisheries management and safety management are not ...

  • Bakteriell gjellebetennelse hos rognkjeks (Cyclopterus lumpus) 

    Furnesvik, Lisa; Erkinharju, Toni; Hansen, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
    Veterinærinstituttet mottok i januar i år en innsendelse fra et settefiskanlegg for rognkjeks. Rognkjeksen var 10-13 gram og uvaksinert. Settefiskanlegget er et gjennomstrømningsanlegg med sjøvann. Det var mistanke om gjelleproblematikk da det ble rapportert om døde individer med utspilte gjellelokk og bleke gjeller. Ved Veterinærinstituttet ble det gjennomført histopatologiske og immunhistokjemiske ...
  • Niche separation between two dominant crustacean predators in European estuarine soft-bottom habitats 

    Siegenthaler, Andjin; Wangensteen, Owen S.; Benvenuto, Chiara; Lollobrigidi, Riccardo; Mariani, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-05)
    Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them to cope with abundant but highly variable prey communities. The assessment of trophic relationships in shallow soft-bottom habitats is, however, challenging and often complicated by the bias and low resolution of the analytical tools available ...
