Could green artificial light reduce bycatch during Barents Sea Deep-water shrimp trawling?
Larsen, Roger B.; Herrmann, Bent; Sistiaga, Manu Berrondo; Brcic, Jure; Brinkhof, Jesse; Tatone, Ivan (Journal article; Peer reviewed, 2018-08)The Nordmøre grid is widely used in shrimp trawls to reduce the bycatch of fish species. However, small-sized fish species and juveniles still pass through the grid and enter the codend, along with the targeted shrimp. ... -

Effect of lifting the sweeps on bottom trawling catch efficiency on the Northeast arctic cod trawl fishery
Sistiaga, Manu Berrondo; Grimaldo, Eduardo; Herrmann, Bent; Larsen, Roger B.; Tatone, Ivan (SINTEF Fiskeri og havbruk;A26220, Research report, 2014-07-01)Fuel consumption and environmental concerns have led bottom trawlers fishing for cod (Gadus morhua) in the Barents Sea to use semi-pelagic doors. However, this change may affect fish herding and consequently the catch ... -
Fishing efficiency of biodegradable PBSAT gillnets and conventional nylon gillnets used in Norwegian cod (Gadus morhua)and saithe (Pollachius virens)fishery.
Grimaldo, Eduardo; Herrmann, Bent; Vollstad, Jørgen; Su, Biao; Føre, Heidi Moe; Larsen, Roger B.; Tatone, Ivan (Journal article; Peer reviewed, 2018-09-10)Fishing trials were carried out to compare the relative fishing efficiency of gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate, PBSAT) with conventional (nylon) nets.
