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 ... -
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, ... -

Can a large-mesh sieve panel replace or supplement the Nordmøre grid for bycatch mitigation in the northeast Atlantic deep-water shrimp fishery?
Jacques, Nadine; Herrmann, Bent; Larsen, Roger B.; Sistiaga, Manu Berrondo; Brčić, Jure; Gökçe, Gökhan; Brinkhof, Jesse (Journal article; Peer reviewed, 2019)The Nordmøre grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass through the grid and enter the ... -
Quantification of bell-shaped size selectivity in shrimp trawl fisheries using square mesh panels and a sorting cone after a Nordmøre grid
Sistiaga, Manu Berrondo; Herrmann, Bent; Larsen, Roger B.; Brinkhof, Jesse (Peer reviewed; Journal article, 2019)Shrimp trawlers in the Barents Sea use a Nordmøre sorting grid ahead of a small-mesh codend to avoid bycatch while catching shrimps efficiently. However, small fish can still pass through the grid to enter the codend, which ... -
Release efficiency and selectivity of four different square mesh panel configurations in the Basque mixed bottom trawl fishery
Cuende, Elsa; Arregi, Luis; Herrmann, Bent; Sistiaga, Manu Berrondo; Basterretxea, Mikel (Journal article; Peer reviewed, 2020)Reduction of discards from the Basque mixed bottom trawl fishery is a challenge. To improve the selective properties of the gear used by the fleet and supplement codend size selection, a square mesh panel (SMP) installed ... -
Stimulating release of undersized fish through a square mesh panel in the Basque otter trawl fishery
Cuende, Elsa; Arregi, Luis; Herrmann, Bent; Sistiaga, Manu Berrondo; Onandia, Inigo (Journal article; Peer reviewed, 2019)Discards of regulated species in the Basque mixed trawl fishery are a challenge. In 2006, a square mesh panel (SMP) was introduced in the fishery to increase the release efficiency of undersized fish. However, studies have ...
