A catch limitation device to avoid excessive catches in the blue whiting (Micromesistius poutassou) Northeast Atlantic pelagic trawl fishery
Ingólfsson, Ólafur Arnar; Breen, Michael; Rosen, Shale; Sistiaga, Manu; Jørgensen, Terje; Lilleng, Dagfinn; Saltskår, Jostein; Kvalvik, Liz Beate Kolstad; Hannaas, Sigurd; Pettersen, Hermann (Peer reviewed; Journal article, 2022)Blue whiting (Micromesistius poutassou) is harvested in the Northeast Atlantic by a multinational fleet of pelagic trawlers. Occasionally, vessels take catches which exceed their remaining holding capacity and in extreme ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
Jacques, Nadine; Cerbule, Kristine; Pettersen, Hermann; Herrmann, Bent; Ingólfsson, Ólafur; Sistiaga, Manu Berrondo; Larsen, Roger B.; Brinkhof, Jesse; Grimaldo, Vela Eduardo; Brčić, Jure; Lilleng, Dagfinn (Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -

Fangstkontroll i kolmulefisket — M/S Morten Einar, mars 2023
Ingólfsson, Ólafur Arnar; Kvalvik, Liz Beate Kolstad; Pettersen, Hermann (Toktrapport;2023 - 15, Research report, 2023)Prosjektet fokuserer på å utarbeide tekniske innretninger for å redusere faren for sprenging av trålposer i fisket etter kolmule. Fisket etter kolmule med norske fartøy foregår i all hovedsak med pelagisk trål og i størst ... -
Forsøk med sekkeforlengelser av kvadratiske masker i snurrevad — Tokt med snurrevadfartøyet Båragutt, mai 2022
Ingólfsson, Ólafur Arnar; Humborstad, Odd Børre; Kvalvik, Liz Beate Kolstad; Pettersen, Hermann (Toktrapport;2022 - 11, Research report, 2022)I fiske etter hyse med snurrevad brukes det som regel «sekkeforlengelser» av diamantmasker foran den obligatoriske kvadratmaskesekken. I disse forsøkene ble det foretatt parvise sammenligninger av diamantmaskeforlengelse ... -
