    Are fishery management upgrades worth the cost? 
    Mangin, Tracey; Costello, Christopher; Anderson, James; Arnason, Ragnar; Elliott, Matthew; Gaines, Steve D.; Hilborn, Ray; Peterson, Emily; Sumaila, Rashid (Public Library of Science (PLoS), 2018-09-20)
    Many analyses of fishery recovery have demonstrated the potential biological and economic benefits of management reform, but few have compared these to the associated costs of management upgrades, which can be substantial. This study aims to determine ...

    A century of fish growth in relation to climate change, population dynamics and exploitation 
    Denechaud, Côme; Smoliński, Szymon; Geffen, Audrey J.; Godiksen, Jane A.; Campana, Steven (Wiley, 2020-08-20)
    Marine ecosystems, particularly in high-latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes in their environment is ...

    Change in Atlantic cod migrations and adaptability of early land-based fishers to severe climate variation in the North Atlantic 
    Edvardsson, Ragnar; Patterson, William P.; Bárðarson, Hlynur; Timsic, Sandra; Ólafsdóttir, Guðbjörg Ásta (Cambridge University Press (CUP), 2019-03-04)
    We use biochemical, biological, archaeological, and historical analysis to examine relationships between Atlantic cod migration, sea temperature, and shifts in the distribution and occupancy of historical fishing sites in Iceland during the last ...

    Effects of fish movement assumptions on the design of a marine protected area to protect an overfished stock 
    Cornejo-Donoso, Jorge; Einarsson, Baldvin; Birnir, Bjorn; Gaines, Steven D. (Public Library of Science (PLoS), 2017-10-12)
    Marine Protected Areas (MPA) are important management tools shown to protect marine organisms, restore biomass, and increase fisheries yields. While MPAs have been successful in meeting these goals for many relatively sedentary species, highly mobile ...

    Gannets are not attracted to fishing vessels in Iceland—potential influence of a discard ban and food availability 
    Clark, Bethany L; Vigfúsdóttir, Freydís; Jessopp, Mark J; Burgos, Julian M; Bodey, Thomas W; Votier, Stephen C (Oxford University Press (OUP), 2019-12-04)
    Fisheries produce large amounts of waste, providing food subsidies for scavengers. Discards influence seabird movement, demography and community structure, but little is known about seabird-fishery interactions where discarding is banned. Here, we ...

    Seasonal flows of economic benefits in small-scale fisheries in Liberia: A value chain analysis 
    jueseah, alvin slewion; Knutsson, Ogmundur; Kristofersson, Dadi; Tómasson, Tumi (Elsevier BV, 2020-09)
    Artisanal fisheries employ small simple craft making fishers, processors and traders vulnerable to seasonal fluctuations. This study examines effects of seasonality on supply, trading relationships and benefits distribution in two small-scale fisheries ...
