    • The Effect of Buffer Towing on Quality Aspects of Frozen and Thawed Atlantic Cod (Gadus Morhua) 

      Esaiassen, Margrethe; Jensen, Tonje Kristin; Eilertsen, Venil T.; Larsen, Roger B.; Olsen, Stein Harris; Tobiassen, Torbjørn Inge (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-16)
      A large part of the Northeast Atlantic cod caught with trawls is landed frozen, processed, and sold thawed. Many trawlers have adapted a fishing practice termed ‘buffer towing’, causing probability for poor exsanguination and fillet redness. Here, the effect of buffer towing upon color and hemoglobin concentration in cod loin section is studied, and the development of TVB-N during chilled storage ...

    • Effect of Codend Design and Postponed Bleeding on Hemoglobin in Cod Fillets Caught by Bottom Trawl in the Barents Sea Demersal Fishery 

      Jensen, Tonje Kristin; Tobiassen, Torbjørn Inge; Heia, Karsten; Møllersen, Kajsa; Larsen, Roger B.; Esaiassen, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-03)
      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 ...

    • Effect of the T90-codend on the catch quality of cod (Gadus morhua) compared to the conventional codend configuration in the Barents Sea bottom trawl fishery 

      Jensen, Tonje Kristin; Brinkhof, Jesse; Lindberg, Stein-Kato; Tobiassen, Torbjørn Inge; Heia, Karsten; Olsen, Stein Harris; Larsen, Roger B.; Esaiassen, Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-18)
      The aim of this study was to compare the catch quality of Northeast Atlantic cod (Gadus morhua) in the Barents Sea bottom trawl fishery caught using the conventional configuration (a sorting grid followed by a diamond mesh (T0) codend) and a T90° turned mesh codend (T90) without a grid. Twenty hauls were conducted, consisting of 10 hauls with the conventional configuration and 10 hauls with the ...

    • Kvalitetsutfordringer på stor snurrevadtorsk - årsaker og mulige tiltak 

      Tobiassen, Torbjørn Inge; Joensen, Sjúrður; Kristoffersen, Silje; Martinsen, Gustav; Hansen, Kristin Beate; Olsen, Stein Harris; Esaiassen, Margrethe (Research report; Forskningsrapport, 2024-01-22)
      Stor snurrevadfanget fisk har andre typer skader enn fisk som er fanget med andre redskap, eksempelvis garn. Målsettingen med arbeidet som presenteres her var å kartlegge type og omfanget av skader på stor snurrevadfanget torsk, samt finne årsakene til slike skader. Det synes å bli flere innvendige skader på snurrevadfanget fisk, slik som knekt rygg og bloduttredelser nær svømmeblæra. Disse ...
