    • Combining selection models and population structures to inform fisheries management: a case study on hake in the Mediterranean bottom trawl fishery 

      Mytilineou, Chryssi; Herrmann, Bent; Kavadas, Stefanos; Smith, Chris J.; Megalofonou, Persefoni (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
      The reduction of juvenile catch and discards are important targets in fisheries policy. This work examines how selection models can predict the size structure (LFD) of discards and landings considering the effects of area, time period, gear and fisher behaviour. Additional exploitation indicators related to the gear used, fisher's selection pattern, and discards were also estimated. The approach is ...

    • Impacts on biodiversity from codend and fisher selection in bottom trawl fishing 

      Mytilineou, Chryssi; Herrmann, Bent; Smith, Christopher j.; Mantopoulou-Palouka, Danai; Anastasopoulou, Aikaterini; Siapatis, Apostolos; Sala, Antonello; Megalofonou, Persefoni; Papadopoulou, Nadia; Vassilopoulou, Vassiliki; Stamouli, Caterina; Kavadas, Stefanos; Lefkaditou, Evgenia; Nicolaidou, Artemis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-22)
      Fisheries have important impacts on marine biodiversity. In this work, combined information on the abundance, species richness, diversity indices, species composition, trophic level and vulnerability index were examined for the first-time to detect differences in five units related to trawl fishing: the fish assemblage entering the trawl codend, and the escaping, retained, discarded and landed ...
