Analysis of reproductive traits reveals complex population dynamics on a small geographical scale in Atlantic herring
Müller, Jonas; dos Santos Schmidt, Thassya Christina; Seljestad, Gaute Wilhelmsen; Clemmensen, Catriona; Gröger, Joachim; Berg, Florian (Peer reviewed; Journal article, 2023)Atlantic herring (Clupea harengus) has a complex population structure and displays a variety of reproductive strategies. Differences in reproductive strategies among herring populations are linked to their time of spawning, ... -
Distinct genetic clustering in the weakly differentiated polar cod, Boreogadus saida Lepechin, 1774 from East Siberian Sea to Svalbard
Sanchez, Maria Quintela; Bhat, Shripathi; Præbel, Kim; Gordeeva, Natalia; Seljestad, Gaute Wilhelmsen; Hanebrekke, Tanja Lexau; Mateos-Rivera, Alejandro; Vikebø, Frode Bendiksen; Zelenia, Daria; Cheng, Chi-Hing Christina; Johansen, Torild (Peer reviewed; Journal article, 2021)The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of ... -
Genetic Stock Identification Reveals Mismatches Between Management Areas and Population Genetic Structure in a Migratory Pelagic Fish
Seljestad, Gaute Wilhelmsen; Quintela, Maria; Bekkevold, Dorte; Pampoulie, Christophe; Farrell, Edward D.; Kvamme, Cecilie; Slotte, Aril; Dahle, Geir; Sørvik, Anne Grete Eide; Pettersson, Mats E.; Andersson, Leif; Folkvord, Arild; Glover, Kevin Alan; Berg, Florian (Peer reviewed; Journal article, 2024)Sustainable fisheries management is important for the continued harvest of the world's marine resources, especially as they are increasingly challenged by a range of climatic and anthropogenic factors. One of the pillars ... -
Growth of spring- and autumn-spawned larvae of Atlantic herring Clupea harengus: a long-term experiment mimicking seasonal light conditions
Berg, Florian; Seljestad, Gaute Wilhelmsen; Folkvord, Arild (Peer reviewed; Journal article, 2024)Atlantic herring Clupea harengus populations differ in their spawning time, and spring- and autumn-spawning populations are genetically distinct. Offspring of these populations encounter seasonal variations in productivity. ... -
Scrutinizing the current management units of the greater argentine in the light of genetic structure
Quintela, Maria; Seljestad, Gaute Wilhelmsen; Dahle, Geir; Hallfredsson, Elvar Halldor; Enberg, Katja Susanna; Langbehn, Tom; Jansson, Eeva; Glover, Kevin Alan; Westgaard, Jon-Ivar (Peer reviewed; Journal article, 2024)The greater argentine is a benthopelagic fish with a northern amphi-Atlantic and southern Arctic distribution. Landings of this species have been steadily increasing since the early 2000s, mainly for ultra-processed fish ...
