• Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment 

      Ferter, Keno; Hartmann, Klaas; Kleiven, Alf Ring; Moland, Even; Olsen, Esben Moland (Journal article; Peer reviewed, 2014-10-07)
      Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ...
    • Dive to survive: effects of capture depth on barotraumaand post-release survival of Atlantic cod (Gadus morhua)in recreational fisheries 

      Ferter, Keno; Weltersbach, Marc Simon; Humborstad, Odd Børre; Fjelldal, Per Gunnar; Sambraus, Florian; Strehlow, Harry Vincent; Vølstad, Jon Helge (Journal article; Peer reviewed, 2015-06-04)
      Atlantic cod (Gadus morhua) caught in recreational fisheries are commonly released, often with barotrauma after rapid decompression. Mouth-hooked, non-bleeding cod kept in a floating net pen showed mortalities ≥40% when ...
    • Estimating and mitigating post-release mortality of European eel by combining citizen science with a catch-and-release angling experiment 

      Weltersbach, Marc Simon; Strehlow, Harry Vincent; Ferter, Keno; Klefoth, Thomas; de Graaf, Martin; Dorow, Malte (Journal article; Peer reviewed, 2018)
      Several anguillid eel species have experienced severe population declines over the past decades, particularly the European eel (Anguilla anguilla), which is listed as critically endangered by the International Union for ...
    • Hook shedding and post-release fate of deep-hooked European eel 

      Weltersbach, Marc Simon; Ferter, Keno; Sambraus, Florian; Strehlow, Harry Vincent (Journal article; Peer reviewed, 2016-05-02)
      The European eel (Anguilla anguilla) is a commercially and recreationally important fishery target species. In the last decades, the eel has experienced dramatic stock declines and has been listed as critically endangered. ...
    • Hummerfisket 2017 og 2018: Innsats og fangst 

      Kleiven, Alf Ring; Lyle, Jeremy; Ferter, Keno; Espeland, Sigurd Heiberg; Kleiven, Portia Joy Nillos; Christensen, Lene; Vølstad, Jon Helge (Rapport fra havforskningen;2019 - 39, Research report, 2019)
      I 2017 ble det innført obligatorisk påmelding til hummerfisket for både fritidsfiskere og yrkesfiskere. Dette har lagt grunnlaget for muligheten til å beregne total innsats og fangst av hummer i Norge. Etter hummersesongen ...

      Marine recreational fishing (MRF) is a high-participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative ...
    • The impact of marine recreational fishing on key fish stocks in European waters 

      Radford, Zachary; Hyder, Kieran; Zarauz, Lucía; Mugerza, Estanis; Ferter, Keno; Prellezo, Raul; Strehlow, Harry Vincent; Townhill, Bryony; Lewin, Wolf-Christian; Weltersbach, Marc Simon (Journal article; Peer reviewed, 2018)
      Marine recreational fishing (MRF) has been shown to substantially contribute to fishing mortality of marine fish. However, European MRF catches are only quantified for a small number of stocks, so it is unclear whether a ...
    • Towards more efficient longline fisheries: fish feeding behaviour, bait characteristics and development of alternative baits
