Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
Jacques, Nadine; Pettersen, Hermann; Cerbule, Kristine; Herrmann, Bent; Ingólfsson, Ólafur Arnar; 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, ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery with a large mesh top panel
Cerbule, Kristine; Jacques, Nadine; Pettersen, Hermann; Ingólfsson, Ólafur Arnar; Herrmann, Bent; Grimaldo, Eduardo; Larsen, Roger B.; Brinkhof, Jesse; Sistiaga, Manu; Lilleng, Dagfinn; Brčić, Jure (Peer reviewed; Journal article, 2021)In the Northeast Atlantic deep-water shrimp (Pandalus borealis) trawl fishery, the bycatch of juvenile fish and shrimp represents a problem. This study evaluated if inserting a 200 mm mesh size top-panel in the last three ... -
The effect of grid size on catch efficiency and by-catch in the demersal trawl fishery for Norway pout (Trisopterus esmarkii)
Brinkhof, Jesse; Grimaldo Vela, Eduardo Enrique; Herrmann, Bent; Pettersen, Hermann (Peer reviewed; Journal article, 2022)Norway pout (Trisopterus esmarkii) is caught with large trawls with small meshed codends, inevitably causing the fishery to have large by-catch issues. To reduce the amount of by-catch, a rigid sorting grid was made ... -
Improved bycatch reduction in the mixed demersal trawl fishery for Norway pout (Trisopterus esmarkii)
Grimaldo, Eduardo; Brinkhof, Jesse; Herrmann, Bent; Cerbule, Kristine; Grimsmo, Leif; Pettersen, Hermann (Peer reviewed; Journal article, 2022)In this study, we compared the bycatch reduction capacity of a trawl fitted with a standard rigid sorting grid with that of a trawl fitted with a newly developed, flexible system called the Excluder. We conducted the fishing ...
