    • Ghost fishing by self-baited lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery 

      Cerbule, Kristine; Herrmann, Bent; Larsen, Roger Bertram; Yu, Mengjie (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-14)
      Unintended continuous capture or so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear produces negative environmental impact on marine life and nature conservation. The risk of ghost fishing in pots could be high due to potential self-baiting resulting from mortality of ghost fished catch. Self-baiting may increase ghost fishing by further attracting marine organisms, ...
