    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      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, selectivity is based on a sorting grid followed by a diamond mesh codend. However, the retention of juvenile fish as well as undersized shrimp is still a problem. In this study, ...

    • The effect of white and green LED-lights on the catch efficiency of the Barents Sea snow crab (Chionoecetes opilio) pot fishery 

      Cerbule, Kristine; Herrmann, Bent; Grimaldo, Vela Eduardo; Grimsmo, Leif; Vollstad, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-05)
      In commercial snow crab (Chionoecetes opilio) fishery, the catch efficiency of the conical pots is important for increasing the profitability of the industry. This study evaluated the effect of adding green and white light emitting diodes (LED) on the catch efficiency of commercially used conical pots. The results from the field experiments showed that inserting artificial lights significantly ...
