Analysis of coastal cod (Gadus morhua L.) sampled on spawning sites reveals a genetic gradient throughout Norway's coastline
Dahle, Geir; Quintela, María; Johansen, Torild; Westgaard, Jon-Ivar; Besnier, Francois; Aglen, Asgeir; Jørstad, Knut Eirik; Glover, Kevin (Peer reviewed; Journal article, 2018-07-09)Background. Atlantic cod (Gadus morhua L.) has formed the basis of many economically significant fisheries in the North Atlantic, and is one of the best studied marine fishes, but a legacy of overexploitation has depleted ... -
Coincident mass occurrence of gelatinous zooplankton in Northern Norway
Knutsen, Tor; Hosia, Aino; Falkenhaug, Tone; Skern-Mauritzen, Rasmus; Wiebe, Peter H.; Larsen, Roger B.; Aglen, Asgeir; Berg, Erik (Peer reviewed; Journal article, 2018-05-23)In autumn 2015, several sources reported observations of large amounts of gelatinous material in a large north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible ... -
Genetic management of mixed-stock fisheries "real-time": The case of the largest remaining cod fishery operating in the Atlantic in 2007-2017
Dahle, Geir; Johansen, Torild; Westgaard, Jon-Ivar; Aglen, Asgeir; Glover, Kevin (Peer reviewed; Journal article, 2018-09)Fish stocks represent fundamental units in fisheries management, and their identification, especially in mixed-fisheries, represents one of the primary challenges to sustainable harvest. Here, we describe the first “real-time” ... -
“Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod
Johansen, Torild; Westgaard, Jon-Ivar; Seliussen, Bjørghild Breistein; Nedreaas, Kjell Harald; Dahle, Geir; Glover, Kevin; Kvalsund, Roger; Aglen, Asgeir (Peer reviewed; Journal article, 2017-05)With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ...
