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 ... -
Artificial light improves size selection for northern shrimp (Pandalus borealis) in trawls
Ingólfsson, Ólafur Arnar; Jørgensen, Terje; Sistiaga, Manu Berrondo; Kvalvik, Liz Beate Kolstad (Peer reviewed; Journal article, 2021)Size selection in the northern shrimp (Pandalus borealis) trawl fisheries is a widely studied topic. While the focus has largely been on codend and grid selectivity, studies have shown the importance of other design changes ... -
Increasing catch efficiency for Nephrops in deep-water shrimp (Pandalus borealis) trawl fisheries
Ingólfsson, Ólafur Arnar; Jørgensen, Terje; Sistiaga, Manu; Herrmann, Bent; Kvalvik, Liz Beate Kolstad (Peer reviewed; Journal article, 2022)In Skagerrak and the North Sea, coastal vessels harvest deep-water shrimp (Pandalus borealis) in a mixed fishery, in which catches of Nephrops (Nephrops norvegicus) are of economic importance for the fleet. Fishermen ... -
Is there a limit to the potential effects of shortening lastridge ropes on the size selectivity of diamond mesh codends?
Sistiaga, Manu; Herrmann, Bent; Brinkhof, Jesse; Larsen, Roger B.; Santos, Juan; Stepputtis, Daniel; Brinkhof, Ilmar; Jacques, Nadine; Cerbule, Kristine; Petetta, Andrea; Cuende, Elsa; Kvalvik, Liz Beate Kolstad (Peer reviewed; Journal article, 2023)Shortening codend lastridge ropes can be an effective fishing gear modification to improve the size selection properties in diamond mesh codends.
