Combination of a sorting grid and a square mesh panel to optimize size selection in the North-East Arctic cod (Gadus morhua) and redfish (Sebastes spp.) trawl fisheries
Sistiaga, Manu Berrondo; Herrmann, Bent; Grimaldo, Eduardo; Larsen, Roger B.; Olsen, Leonore; Brinkhof, Jesse; Tatone, Ivan (Journal article; Peer reviewed, 2017)Sorting grids and square mesh panels are the two most-applied technical devices to supplement codend size- and species-selection in demer- sal trawls. In the Barents Sea gadoid fishery, the compulsory size-selectivity ... -
Comparison of fishing efficiency between biodegradable PBSAT gillnets and conventional nylon (PA) gillnets
Grimaldo, Eduardo; Herrmann, Bent; Su, Biao; Føre, Heidi Moe; Vollstad, Jørgen; Olsen, Leonore; Larsen, Roger B.; Tatone, Ivan (Journal article; Peer reviewed, 2018)Gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate (PBSAT) were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon ... -
Effect of gear soak time on size selection in the snow crab pot fishery
Olsen, Leonore; Herrmann, Bent; Sistiaga, Manu Berrondo; Grimaldo, Eduardo (Journal article; Peer reviewed, 2019)In the commercial pot fishery for snow crab (Chionocetes opilio), size selection by the pots is important for reducing catch sorting and unintended mortality. In addition to mesh size and shape, selection in the pots relies ... -
Effect of pot design on the catch efficiency of snow crabs (Chionoecetes opilio) in the Barents Sea fishery
Olsen, Leonore; Herrmann, Bent; Grimaldo, Eduardo; Sistiaga, Manu Berrondo (Journal article; Peer reviewed, 2019-07-18)The snow crab (Chioneocetes opilio) fishery in the Barents Sea is carried out by large offshore vessels, as the fishing grounds are located far from shore and the gear must be transported back and forth over long distances. ...
