    • Acoustic abundance estimation of the stock of Norwegian spring spawning herring, winter 1995- 1996 

      Foote, Kenneth G.; Ostrowski, Marek; Røttingen, Ingolf; Engås, Arill; Hansen, Kaare A.; Hauge, Kjellrun Hiis; Skeide, Roar L.; Slotte, Aril; Torgersen, Øyvind (ICES CM Documents;1996/H:33, Working paper, 1996)
      Standard echo integration methodology has been applied to the stock of Norwegian spring spawning herring (Clupea harengus) wintering in the Ofotfjord-Tysfjord-Vestfjord system during late autumn 1995 and early winter ...

    • Effect of attractant distribution on catch rate and size selection of Norway lobster caught by pots 

      Bjordal, Åsmund; Løkkeborg, Svein; Skeide, Roar L. (ICES CM Documents;1991/B:45, Working paper, 1991)
      In comparative fishing trials with Norway lobster (Nephrops norvegicus) pots, the attractant property of an aqueous extract of mackerel was tested against that of natural mackerel bait. The catch rate of the natural ...

    • Estimates of towing time in surveys 

      Huse, Irene; Michalsen, Kathrine; Skeide, Roar L. (ICES CM documents, Working paper, 2002)
      To decide the start and stop time for a survey haul the current method used in Norwegian sampling are the data from the door sensors and height sensors of the trawl. When the trawl has achieved its right geometry, the start ...

    • Grid-sorting of penned saithe 

      Misund, Ole Arve; Skeide, Roar L. (ICES CM Documents;1992/B:11, Working paper, 1992)
      Size selection of penned saithe was obtained by forcing the fish against an adjustable grid mounted in the end of net pens. The size selection was rather sharp, with a selection range of about 5 cm only. All fish forced ...

    • Size selective effects of a plastic body on longline hooks 

      Løkkeborg, Svein; Bjordal, Åsmund; Skeide, Roar L. (ICES CM Documents;1991/B:46, Working paper, 1991)
      The potential for improving size selectivity of longlines by using a plastic body attached to the hook shank was tested in a fishing trial for tusk (Brosme brosme), ling (Molva molva) and haddock (Melanogrammus aeglefinus). ...

    • Testing of a new hook design (E-Z-Baiter) through comparative longline fishing trials 

      Skeide, Roar L.; Bjordal, Åsmund; Løkkeborg, Svein (ICES CM Documents;1986/B:25, Working paper, 1986)
