  • Establishment of killer whale cell cultures and their responses to pollutant exposure 

    Bjørneset, Juni (Master thesis; Mastergradsoppgave, 2022-03-15)
    The cosmopolitan apex predator killer whale (Orcinus orca) is one of the species worldwide with the highest levels of persistent organic pollutants (POPs) in their tissues. The knowledge of how POPs may affect the species is limited, likely due to the ethical, legal, and practical challenges of researching toxicology on free-ranging marine mammals. The use of in vitro models has proved to be a ...
  • Exploring the gap between top-down sustainability objectives and perceived local sustainability challenges – the case of Senja Municipality 

    Ahlquist, Ina Helene (Master thesis; Mastergradsoppgave, 2023-08-14)
    Achieving social, environmental, and economic sustainability has become the aim of nations and organizations across the globe. One of the attempts to operationalize sustainability is through the integration of the sustainable development goals in coastal governance. However, the perceived characteristics of challenges for sustainability, and thus also solutions to them, may differ depending on the ...
  • A Novel Biosurfactant-Based Oil Spill Response Dispersant for Efficient Application under Temperate and Arctic Conditions 

    Farooq, Umer; Szczybelski Ciordia, Ariadna Sabina; Ferreira, Frederico Castelo; Faria, Nuno Torres; Netzer, Roman (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-15)
    Synthetic oil spill dispersants have become essential in offshore oil spill response strategies. However, their use raises significant concerns regarding toxicity to phyto- and zooplankton and other marine organisms, especially in isolated and vulnerable areas such as the Arctic and shorelines. Sustainable alternatives may be developed by replacing the major active components of commercial dispersants ...

  • Overskudd og ressursrente -mer for Nord-Norge? 

    Flaaten, Ola; Heen, Eirik Eriksen; Heen, Knut (Chapter; Bokkapittel, 2023)
    Artikkelen beskriver utviklingen i fiskeri- og havbruksnæringen i Nord-Norge, med spesiell vekt på Finnmark og Nord-Troms. Norsk økonomisk sone har her det biologiske grunnlaget for landets viktigste fiskerier. Fiskeriene har gått fra å være en åpen næring til en lukket og eksklusiv «klubb». Konsekvensene for næringen i Nord-Norge har vært sentralisering i færre enheter og svekking av mange lokalsamfunn. ...
  • Cross-cultural co-creation of a tourist site: the emic and etic makings 

    Lee, Young-Sook; Mathisen, Line; Søreng, Siri Ulfsdatter (Chapter; Bokkapittel, 2023-10-17)
    This chapter discusses how an Arctic destination, North Cape, is co-created through time and space aided by tourists' engagement. We present two cases: (1) Thai visitors to the North Cape; and (2) North Cape as a brand in South Korea, drawing on qualitative methods. We argue that cross-cultural co-creation in tourism experiences depends on the knowledge of different emic and etic perceptions of the ...
  • Mining various genomic resources to resolve old alpha-taxonomy questions: A test of the species hypothesis of the Proteocephalus longicollis species complex (Cestoda: Platyhelminthes) from salmonid fishes 

    Brabec, Jan; Rochat, Eloïse Coralie; Knudsen, Rune; Scholz, Tomas; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-24)
    High-throughput sequencing strategies became commonly employed to study non-model parasites, but the corresponding genomes and transcriptomes were seldom mined following the original publication. Similar to the data generated with genome skimming techniques based on shallow-depth shotgun gen omes, various genomic and transcriptomic resources can be screened for useful molecular phylogenetic markers ...
  • Comparative analysis of the cytoarchitecture of the excretory bladder of adult Digenea (Platyhelminthes) with consideration of the presence of mineralized excretory corpuscles in marine and freshwater adult worms 

    Poddubnaya, Larisa G.; Hemmingsen, Willy; MacKenzie, Ken (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-01)
    The ultrastructural differences are shown between the cytoarchitecture of the excretory bladder and excretory inclusions in four digenean species, two azygiids, the marine Otodistomum cestoides and the freshwater Azygia lucii, the marine derogenid Derogenes varicus and the freshwater allocreadiid Acrolichanus auriculatus. The unusual cytoarchitecture of the bladder epithelium of the azygiid digeneans, ...
  • Simple pot modification improves catch efficiency and species composition in a tropical estuary mud crab (Scylla serrata) fishery 

    Madhu, V.R.; Anand, Sreelakshmi B.; Cerbule, Kristine; Herrmann, Bent (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-08)
    Pots are widely used fishing gear type for targeting different crustacean and fish species. Pot entrance size and design are among the most important technical parameters that influence the catch efficiency of certain species. An optimal pot entrance design should allow an efficient entry for the target species while preventing subsequent escape. The tropical estuary pot fishery targeting mud crab ...
  • Impact of ground gear design on catch efficiency in demersal trawl fishery 

    Fakıoğlu, Y.E.; Gökçe, G.; Özbilgin, H.; Cerbule, Kristine; Herrmann, Bent (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-03)
    The choice of ground gear design in demersal trawls can significantly affect both catch composition and efficiency. The preference for a specific design depends on the fishing ground. In the North-Eastern Mediterranean, two types of ground gears, Single Line and Double Line are commonly used. Therefore, this study compared the catch performance for trawls using these ground gears during research ...
  • Effect of artificial lights on catch efficiency and capture patterns in Asian paddle crab (Charybdis japonica) gillnet fishery 

    Yu, Mengjie; Herrmann, Bent; Cerbule, Kristine; Liu, Changdong; Zhang, Liyou; Tang, Yanli (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-22)
    The gillnet fishery targeting Asian paddle crab (Charybdis japonica) is an important commercial fishery in the Yellow Sea of China. However, low catch rates represent a challenge, and solutions for improving the catch efficiency are crucial for economical sustainability in this fishery. Therefore, we tested whether the use of artificial fishing lights could improve gillnet catch performance. ...
  • Testing of hook sizes and appendages to reduce yelloweye rockfish bycatch in a Pacific halibut longline fishery 

    Lomeli, Mark Joseph Max; Wakefield, W. Waldo; Abele, Meagan; Dykstra, Claude L.; Herrmann, Bent; Stewart, Ian J.; Christie, Gregory C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-03)
    In Pacific halibut (Hippoglossus stenolepis) longline fisheries in the eastern North Pacific Ocean bycatch of yelloweye rockfish (Sebastes ruberrimus) is a concern as their stock status along the U.S. West Coast is “rebuilding” from being “overfished”, the southeast Alaska stock has shown a ∼60% decline since at least 1994 and through 2015 where it stabilized, and the Canadian stock has been recently ...
  • Comparison of physical properties and fishing performance between biodegradable PLA and conventional PA trammel nets in grey mullet (Mugil cephalus) and red-lip mullet (Liza haematocheila) fishery 

    Yu, Mengjie; Tang, Yanli; Min, Minghua; Herrmann, Bent; Cerbule, Kristine; Liu, Changdong; Dou, Yilin; Zhang, Liyou (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-16)
    Marine plastic pollution and continuous capture of marine animals, so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear (ALDFG) are global concerns. This study investigated whether biodegradable polylactic acid (PLA) monofilaments can be used to replace conventionally used non-biodegradable polyamide (PA) in trammel net fishery for limiting ALDFG associated effects. It ...
  • Biological timekeeping in polar environments: lessons from terrestrial vertebrates 

    Hazlerigg, David Grey; Mizumo Tomotani, Barbara; West, Alexander Christopher; Appenroth, Daniel; Wood, Shona Hiedi (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-30)
    The polar regions receive less solar energy than anywhere else on Earth, with the greatest year-round variation in daily light exposure; this produces highly seasonal environments, with short summers and long, cold winters. Polar environments are also characterised by a reduced daily amplitude of solar illumination. This is obvious around the solstices, when the Sun remains continuously above (polar ...
  • Sea, fish, and resource management in the High North 

    Hoel, Alf Håkon (Chapter; Bokkapittel, 2023)
    With more than five times the land area of the kingdom, Norway’s oceans extend from 55 degrees north in the North Sea to 85 degrees north in the Arctic Ocean north of Svalbard – a distance of more than 3,000 kilometres. More than 80 per cent of these sea areas lies to the north of the Arctic Circle. As for natural resources, these sea areas are very productive and sustain large commercial fisheries. ...
  • Sustainability and justice: farm animals in rural tourism and lessons to be learned 

    Bertella, Giovanna (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12)
    Farm animals are virtually ignored in tourism studies concerning sustainability and justice. This study argues that this conflicts with animal ethics and is a missed opportunity to reflect on sustainability and justice in tourism. It adopts an ecofeminist care ethics perspective and conducts autoethnographic research into farm animals, considered ‘silenced’ individuals belonging to a marginalised ...
  • The gift of community 

    Jentoft, Svein (Book; Bok, 2023)
    This book is a followup, or a continuation rather, of the one I published in 2019 as part of the Too Big To Ignore (TBTI) Global Book Series, titled ‘Life Above Water: Essays on Human Experiences of Small-Scale Fisheries’. The design and purpose of the current book are the same. The introduction in the 2019 book could also work here, even if this book has a sharper focus on communities. Both consist ...
  • Comparative assessment of Chinese mitten crab aquaculture in China: Spatiotemporal changes and trade-offs 

    Liu, Xin; Wu, Huijun; Wang, Yuan; Liu, Yajie; Zhu, Hui; Li, Zeru; Shan, Pengguang; Yuan, Zengwei (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-12)
    The increasing human demand for high-quality animal protein has provided impetus for the development of aquaculture. Chinese mitten crab (Eriocheir sinensis) is a catadromous species rapidly being cultured in China but scientific literature documenting its life cycle environmental and economic consequences remains scarce. This study aims to address this gap by examining the spatio-temporal evolution ...
  • The Image Fallacy: Rethinking the Tragedy of the Commons 

    Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
    An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...
