    • Does soak time influence the effect of artificial light on catch efficiency in snow crab (Chionoecetes opilio) pot fishery? 

      Cerbule, Kristine; Herrmann, Bent; Grimaldo, Eduardo; Grimsmo, Leif; Karlsen, Junita D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-09)
      In the Barents Sea commercial snow crab (Chionoecetes opilio) fishery, an increase in catch efficiency of the conical pots is important for the profitability of the industry. Light emitting diodes (LEDs) have previously been tested for increasing catch efficiency of the snow crab pots. These earlier experiments have shown varying results ranging from large increase in snow crab catches to no ...

    • 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 ...

    • Improved bycatch reduction in the mixed demersal trawl fishery for Norway pout (Trisopterus esmarkii) 

      Grimaldo, Eduardo; Brinkhof, Jesse; Herrmann, Bent; Cerbule, Kristine; Grimsmo, Leif; Pettersen, Hermann (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)
      In this study, we compared the bycatch reduction capacity of a trawl fitted with a standard rigid sorting grid with that of a trawl fitted with a newly developed, flexible system called the Excluder. We conducted the fishing trials in the Norway pout (Trisopterus esmarkii) small-meshed trawl fishery in the North Sea. Catch data were analysed by species and length using the catch comparison and catch ...

    • Increasing sustainability in food production by using alternative bait in snow crab (Chionoecetes opilio) fishery in the barents sea 

      Cerbule, Kristine; Grimsmo, Leif; Herrmann, Bent; Grimaldo, Eduardo (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-17)
      The use of food grade wild-captured species as bait for other fisheries questions the sustainability of food production. In pot fisheries, bait is an important factor determining the effectiveness of the gear. In snow crab (Chionoecetes opilio) fishery, the pots are normally baited with squid (Illex sp.) and herring (Clupea harengus). This fishery uses substantial amounts of bait for each ...

    • Prediction of potential net panel selectivity in mesopelagic trawls 

      Grimaldo, Eduardo; Herrmann, Bent; Brčić, Jure; Cerbule, Kristine; Brinkhof, Jesse; Grimsmo, Leif; Jacques, Nadine (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-17)
      The growing interest in harvesting mesopelagic fish species has increased the need for knowledge about how trawls should be designed for optimizing the catch efficiency of these resources. Since the net herding efficiency for small mesopelagic fish species is unknown, trawls targeting these species need to consider the potential net panel selectivity along the entire trawl body. Therefore, trawl ...
