Escape of hake (Merluccius merluccius), horse mackerel (Trachurus trachurus) and blue whiting (Micromesistius poutassou) in codends with shortened lastridge ropes
Cuende, Elsa; Sistiaga, Manu; Herrmann, Bent; Basterretxea, Mikel; Arregi, Luis (Peer reviewed; Journal article, 2022)Diamond meshes in trawl codends have limited openness, which reduces escape opportunities for roundfish. Shortening the lastridge ropes (LR) attached to codend selvedges can increase the availability of open meshes resulting ... -
Optimizing size selectivity and catch patterns for hake (Merluccius merluccius) and blue whiting (Micromesistius poutassou) by combining square mesh panel and codend designs
Cuende, Elsa; Sistiaga, Manu; Herrmann, Bent; Arregi, Luis (Peer reviewed; Journal article, 2022)Gear modifications in fisheries are usually implemented to obtain catch patterns that meet management objectives. In the Basque bottom trawl fishery, gear regulations include the use of a square mesh panel (SMP) placed at ... -
Prediction of square mesh panel and codend size selectivity of blue whiting based on fish morphology
Cuende, Elsa; Arregi, Luis; Herrmann, Bent; Sistiaga, Manu; Aboitiz, Xabier (Peer reviewed; Journal article, 2020)Square mesh panels (SMPs) are selective devices used extensively to supplement codend size selectivity in trawl fisheries. Therefore, predictions of the effect of mesh size in both SMPs and codends on size selectivity are ... -
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 ...
