Increased cultivation and utilization of seaweed are expected to be important pillars of sustainable food security and a robust aquatic economy in the coming years. It is important, therefore, to consider the food ...
  • Effect of Extension Piece Design on Catch Patterns in a Mediterranean Bottom Trawl Fishery 

    Petetta, Andrea; Herrmann, Bent; Virgili, Massimo; Li Veli, Daniel; Brinkhof, Jesse; Lucchetti, Alessandro (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-18)
    The catch composition of bottom trawls is commonly refined and improved through changes in codend design. Measures like reducing the number of meshes in codend circumference or turning diamond netting by 90 degrees are well known to improve the size selectivity of fish species with rounded cross-sectional shape. Based on this we speculated whether the same measures, if applied in other parts of ...
