    • Fish quality and market performance: The case of the coastal fishery for Atlantic cod in Norway 

      Sogn-Grundvåg, Geir; Zhang, Dengjun; Henriksen, Edgar; Joensen, Sjúrður; Bendiksen, Bjørn Inge; Hermansen, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-22)
      This study focuses on fish quality and resource utilization at the ex-vessel level of the value chain. Substantial waste in the form of reduced fish quality is revealed for Atlantic cod landed by the coastal fleet in Norway, with approximately 30% of the sampled cod from 399 catches downgraded, implying reduced value of products in onshore processing. By using an objective quality index for individual ...

    • Government financial transfers to the fish harvesting, processing and aquaculture industries Norway 1990 - 2002 

      Hermansen, Øystein; Flåten, Ola (Working paper; Arbeidsnotat, 2004-03)
      This report investigates and quantifies Norwegian governmental financial transfers (GFT) to primarily the fish harvesting industry, but also the fish processing and aquaculture industries. Focus is on the period 1990 to 2002. The data sources for this report are mainly public accounts of the Ministry of Fisheries, that channelled the bulk of support measures. We also rely heavily on a set of ...

    • Institutional and financial entry barriers in a fishery 

      Bertheussen, Bernt Arne; Dreyer, Bent; Hermansen, Øystein; Isaksen, John Roald (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-18)
      Fishery policies over the past decades have mainly aimed at capacity reduction to preserve overexploited stocks. For that reason, research has focused on exploring incentives to exit fisheries rather than examining entry barriers. However, in quota-regulated fisheries, potential entrants might face substantial institutional and financial barriers, as opposed to incumbents, whose rights might have ...

    • Kapasitetsutvikling og konkurranseforhold – Utvalgte grupper i kystflåten 

      Dreyer, Bent Magne; Hermansen, Øystein; Hogrenning, Egil; Johnsen, Jahn Petter; Nyrud, Thomas; Siikavuopio, Bjørnar; Steinsbø, Silje (Research report; Forskningsrapport, 2022-11-11)
      Denne rapporten oppsummerer resultatene fra prosjektet Drivere for, samt effekten av, kapasitetsutvikling i fiskeflåten finansiert av Fiskeri- og havbruksnæringens forskningsfinansiering (FHF).<p> <p>Prosjektet er et samarbeid mellom Nofima og Norges Arktiske Universitet (UiT) og er gjennomført i perioden 2021 til 2022. Det innebærer blant annet at prosjektet er gjennomført i en periode med ...

    • Kappfiske - problem eller løsning? 

      Flåten, Ola; Hermansen, Øystein (Working paper; Arbeidsnotat, 2005-02)
      Landingene av torsk i Norge er sterkt sesongvarierte. Fangstene i første halvår i årene 1983- 84 utgjorde om lag 85 % av årets totalfangst. I 1986-88 var andelen sunket til om lag 70 %, mens den steg til 80 % i 1999-2000 og til 90 % i 2001-02. Dette landingsmønsteret for kystflåtens fangster av torskefisk er et resultat av en rekke faktorer; fiskens tilgjengelighet, kvalitet, pris, flåtestruktur, ...

    • Seafood from a changing Arctic 

      Troell, Max; Eide, Arne; Isaksen, John Roald; Hermansen, Øystein; Crépin, Anne-Sophie (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-27)
      We review current knowledge about climate change impacts on Arctic seafood production. Large-scale changes in the Arctic marine food web can be expected for the next 40–100 years. Possible future trajectories under climate change for Arctic capture fisheries anticipate the movement of aquatic species into new waters and changed the dynamics of existing species. Negative consequences are ...

    • Spatial and temporal distributions in the Norwegian cod fishery 

      Ashrafi, Tannaz Alizadeh; Eide, Arne; Hermansen, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-25)
      Fisheries are characterized by variations in space and time. This study investigates the characteristics of seasonality in cod trawl fisheries in two distinct areas: the coast along the northern Norway and the high sea area of the Barents Sea. Catch per unit effort (CPUE) is used to proxy variation in stock abundance. A CPUE function has been estimated in the frequency‐domain framework, to detect ...

    • Stubborn fuel tax concessions: The case of fisheries in Norway 

      Isaksen, John Roald; Hermansen, Øystein; Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-11-22)
      In the context of the abolition of traditional subsidies, this paper discusses the persistence of the major remaining subsidy scheme in Norwegian fisheries: exemption from fuel taxes. This reimbursement scheme stems from the late1980s, and has persisted since then under different governments. This paper gives the background to this support against theoretical predictions of the subsidy's effects on ...
