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 (Journal article; Peer reviewed, 2023-02-01)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, ... -
"A cleaner break" - Genetic analysis identifies two major groups of ballan wrasse (Labrus bergylta) within Scandinavia and evidence of phenotype derived divergence
Seljestad, Gaute Wilhelmsen (Master thesis, 2019-06-21)For a long time, sea lice have represented the major financial and fish welfare challenge of the salmonid farming industry. In the late 1980s, the use of parasite-eating cleaner fish, first and foremost wrasses (family ... -
Distinct genetic clustering in the weakly diferentiated 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 (Journal article; Peer reviewed, 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 ... -
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 (Journal article; Peer reviewed, 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. ...
