• Anglerfish Lophius piscatorius L. in Faroese waters. Life history, ecological importance and stock status 

      Ofstad, Lise Helen (Doctoral thesis; Doktorgradsavhandling, 2013-04-16)
      Anglerfish Lophius piscatorius has during the last two decades become a highly exploited resource and is now one of the five most economically important demersal fish species in the Faroese fishery. Despite this, there is at present little information available on the population status of anglerfish in Faroese waters. The main aim of this study is to increase the biological knowledge of anglerfish ...
    • Horizontal and Vertical Migration of Anglerfish Lophius piscatorius in Relation to Hydrography in Faroese Waters 

      Ofstad, Lise Helen; Hátún, Hjálmar; Pedersen, Torstein; Steingrund, Petur; Mikkelsen, Bjarni (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-04)
      Adult anglerfish conduct annual migrations between spawning areas and feeding areas; for Faroese waters this migration has so far not been described. Therefore, anglerfish migration and distribution in Faroese waters was investigated by mark-recapture studies, including data storage tags, as well as data from scientific trawl surveys, commercial trawlers and gillnetters. The fish distribution was ...

      Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here we compile mark–recapture data collected across the North Atlantic to gain insight into the spatial population structure of Greenland halibut (Reinhardtius hippoglossoides), an ...
