Effect of gear design on catch damage on cod (Gadus morhua) in the Barents Sea demersal trawl fishery
Brinkhof, Jesse; Herrmann, Bent; Sistiaga, Manu; Larsen, Roger B.; Jacques, Nadine; Gjøsund, Svein Helge (Peer reviewed; Journal article, 2020)Damage incurred during the catch process is an indicator of the overall quality of fish and fish welfare. Because catch quality is difficult to improve once it has deteriorated, it is important to preserve quality during ... -
Effect of grid section design on trawl size selectivity
Sistiaga, Manu; Herrmann, Bent; Brinkhof, Jesse; Larsen, Roger B. (Peer reviewed; Journal article, 2023)Sorting grids are introduced in trawl fisheries to improve size selectivity and reduce the variability of results obtained with sorting devices constructed of netting e.g., codends. Grids are rigid or semi-rigid structures ... -

Larsen, Roger B.; Herrmann, Bent; Sistiaga, Manu; Brinkhof, Jesse; Cerbule, Kristine; Grimaldo Vela, Eduardo Enrique; Lomeli, Mark JM (Peer reviewed; Journal article, 2022)The introduction of the Nordmøre grid in shrimp trawls has reduced the bycatch of non-target species. In the Norwegian Northern shrimp (Pandalus borealis) fishery, the mandatory selective gear consists of a Nordmøre grid ... -
Ghost fishing efficiency by lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery
Cerbule, Kristine; Herrmann, Bent; Grimaldo, Eduardo; Brinkhof, Jesse; Sistiaga, Manu; Larsen, Roger B.; Bak-Jensen, Zita (Peer reviewed; Journal article, 2023)Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG ... -
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.
