• Does the efficiency of a counter-herding device depend on seabed contact? 

      Melli, Valentina; Krag, Ludvig Ahm; Herrmann, Bent; Karlsen, Junita Diana; Feekings, Jordan (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-06)
      To prevent unwanted fish bycatch from entering the trawl, we modified a counter-herding device, FLEXSELECT, developed for a Northeast Atlantic <i>Nephrops</i> (<i>Nephrops norvegicus</i>) trawl fishery. FLEXSELECT, which was designed to direct fish away from the trawl by means of sweeping ropes in the herding area, has been shown to be highly effective on both roundfish and flatfish species. However, ...
    • Industry-led fishing gear development: Can it facilitate the process? 

      Veiga-Malta, Tiago; Feekings, Jordan; Herrmann, Bent; Krag, Ludvig A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-16)
      In the reformed technical measures regulation, the European Union proposed a greater involvement of the fishing industry in the different managerial aspects of fisheries. However, having the industry as a main actor in gear development presents a new suite of challenges. The industry, while addressing an issue in the fishery, can modify several aspects of a fishing gear simultaneously, without ...
    • A netting-based alternative to rigid sorting grids in the small-meshed Norway pout (Trisopterus esmarkii) trawl fishery 

      Eigaard, Ole R.; Herrmann, Bent; Feekings, Jordan; Krag, Ludvig Ahm; Sparrevohn, Claus R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-28)
      A new bycatch reduction device, termed “Excluder”, is presented as an alternative to a traditional rigid sorting grid, mandatory in the small-meshed Norway Pout (<i>Trisopterus esmarkii</i>) trawl fishery in the North Sea. The fishery is a high-volume fishery with large vessels, large demersal trawls and catches up to 100 tons per haul of this small forage fish. The Excluder is a 30 m long netting-based ...
    • Predicting optimal combinations of by‐catch reduction devices in trawl gears: A meta‐analytical approach 

      Melli, Valentina; Herrmann, Bent; Karlsen, Junita Diana; Feekings, Jordan; Krag, Ludvig Ahm (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-02)
      Global efforts to reduce unwanted catches have led to the development of a vast array of by‐catch reduction devices (BRDs), in particular for mixed trawl fisheries. Some of these BRDs could likely benefit from being combined. However, the number of possible combinations would be prohibitive to be tested experimentally. Therefore, in this study we propose a meta‐analytical approach that combines the ...
    • Understanding and predicting size selection in diamond-mesh cod ends for Danish seining: a study based on sea trials and computer simulations 

      Herrmann, Bent; Krag, Ludvig Ahm; Feekings, Jordan; Noack, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-28)
      Danish seining is an important fishing method used to harvest demersal species. Knowledge about the size selectivity of different demersal species with this type of fishing gear is therefore of importance for managing the exploitation of marine resources. However, there are only limited data on size selection in cod ends in this fishery. Sea trials were therefore carried out to collect size selectivity ...
    • When is enough, enough? Quantifying trade-offs between information quality and sampling effort for fishing gear selectivity data 

      Veiga-Malta, Tiago; Feekings, Jordan; Herrmann, Bent; Krag, Ludvig Ahm (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-21)
      There is general pressure throughout the world’s fisheries for the industry to have greater involvement not only in the development of fishing gears but also in the testing and documentation of their effect. In the European Union, the Common Fisheries Policy of 2013, together with the proposed reform of the technical measures regulation, highlights the need for greater flexibility in fisheries through ...
