Behavior-dependent selectivity of yellowtail flounder (Limanda ferruginea) in the mouth of a commercial bottom trawl
Underwood, Melanie; Winger, Paul D.; Fernø, Anders; Engås, Arill (Journal article; Peer reviewed, 2015-09-02)To improve the efficiency of a commercial bottom trawl for catching yellowtail flounder (Limanda ferruginea), we studied the behavior of individuals in the middle of the trawl mouth. Observations were conducted with ... -
Collecting size-selectivity data for Antarctic krill (Euphausia superba) with a trawl independent towing rig
Krag, Ludvig Ahm; Krafft, Bjørn Arne; Engås, Arill; Herrmann, Bent (Peer reviewed; Journal article, 2018)For the development of efficient trawls to minimize catch loss, escape mortality and potential negative ecosystem impacts from the fishery, the understanding about trawl selectivity processes are crucial. Small crustaceans ... -

Quantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba)
Krafft, Bjørn Arne; Krag, Ludvig Ahm; Engås, Arill; Nordrum, Sigve; Bruheim, Yngve; Herrmann, Bent (Journal article; Peer reviewed, 2016-09-13)Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh ... -
A “snowcrab-bag” attached to the fishing line of Campelen 1800 research trawl : Does it affect the catch rates and species composition in the cod end?
Aglen, Asgeir; Pavlenkov, Alexander; Hjelset, Ann Merete; Fuglebakk, Edvin; Engås, Arill (IMR/PINRO Joint Report Series;, Research report, 2019)For monitoring abundance and distribution of snow crab in the Barents Sea, data from the bottom trawl surveys in winter (February) and in autumn (August-September) are used. The data collected in the autumn survey is ... -
Under-ice observations by trawls and multi-frequency acoustics in the Central Arctic Ocean reveals abundance and composition of pelagic fauna
Ingvaldsen, Randi Brunvær; Eriksen, Elena; Gjøsæter, Harald; Engås, Arill; Schuppe, Birte Katarina; Assmann, Karen; Cannaby, Heather Anne; Dalpadado, Padmini; Bluhm, Bodil (Peer reviewed; Journal article, 2023)The rapid ongoing changes in the Central Arctic Ocean call for baseline information on the pelagic fauna. However, sampling for motile organisms which easily escape vertically towed nets is challenging. Here, we report the ...
