Assessing the performance of statistical classifiers to discriminate fish stocks using Fourier analysis of otolith shape
Smoliński, Szymon; Schade, Franziska M.; Berg, Florian (Peer reviewed; Journal article, 2020)The assignment of individual fish to its stock of origin is important for reliable stock assessment and fisheries management. Otolith shape is commonly used as the marker of distinct stocks in discrimination studies. Our ... -
A combination of genetic and phenotypic characterization of spring- and autumn-spawning herring suggests gene flow between populations
Berg, Florian; Østgaard, Hedda Dugstad; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Journal article; Peer reviewed, 2020)Atlantic herring (Clupea harengus) has complex population structure and dynamics including diverse life histories and spawning times with spring and autumn spawning as the most common modes. Originally, spawning herring ... -
Comparative biology and population mixing among local, coastal and offshore Atlantic herring (Clupea harengus) in the North Sea, Skagerrak, Kattegat and western Baltic
Berg, Florian; Slotte, Aril; Johannessen, Arne; Kvamme, Cecilie; Clausen, Lotte A.W.; Nash, Richard David Marriott (Peer reviewed; Journal article, 2017-10-30)The population structure of Atlantic herring (Clupea harengus) from 13 local, coastal and offshore areas of the North Sea, Skagerrak, Kattegat and western Baltic (northeast Atlantic) was studied using biological and ... -
Comparison of Otolith Microstructure of Herring Larvae and Sibling Adults Reared Under Identical Early Life Conditions
Tonheim, Susanne; Slotte, Aril; Andersson, Leif; Folkvord, Arild; Berg, Florian (Journal article; Peer reviewed, 2020-07-03)Atlantic herring (Clupea harengus) is a euryhaline species, occupying fully marine habitats (35 psu) in the North Atlantic, as well as brackish waters (<20 psu) such as in the adjacent Baltic Sea. We co-reared Atlantic ... -
Earlier hatching and slower growth: a key to survival in the early life history of Norwegian spring spawning herring
Slotte, Aril; Husebø, Åse; Berg, Florian; Stenevik, Erling Kåre; Folkvord, Arild; Fossum, Petter; Mosegaard, Henrik; Vikebø, Frode Bendiksen; Nash, Richard David Marriott (Peer reviewed; Journal article, 2018-10-02)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
Berg, Florian; Shirajee, Samina; Folkvord, Arild; Godiksen, Jane Aanestad; Skaret, Georg; Slotte, Aril (Journal article; Peer reviewed, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci
Han, Fan; Jamsandekar, Minal; Pettersson, Mats; Su, Leyi; Fuentes-Pardo, Angela P.; Davis, Brian W.; Bekkevold, Dorte; Berg, Florian; Casini, Michele; Dahle, Geir; Farrell, Edward D.; Folkvord, Arild; Andersson, Leif (Journal article; Peer reviewed, 2020)Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ... -
Genetic factors have a major effect on growth, number of vertebrae and otolith shape in Atlantic herring (Clupea harengus)
Berg, Florian; Almeland, Oda W.; Skadal, Julie; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Peer reviewed; Journal article, 2018-01-11)Atlantic herring, Clupea harengus, have complex population structures. Mixing of populations is known, but the extent of connectivity is still unclear. Phenotypic plasticity results in divergent phenotypes in response to ... -
Genetic origin and salinity history influence the reproductive success of Atlantic herring
Berg, Florian; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Peer reviewed; Journal article, 2018)Atlantic herring populations inhabit environments ranging in salinity from fully marine to nearly freshwater, but their relative reproductive success in these respective environments remains unclear. We conducted factorial ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
Sanchez, Maria Quintela; Richter-Boix, Alex; Bekkevold, Dorte; Kvamme, Cecilie; Berg, Florian; Jansson, Eeva; Dahle, Geir; Besnier, Francois; Nash, Richard David Marriott; Glover, Kevin Alan (Journal article; Peer reviewed, 2021)Habitat changes represent one of the five most pervasive threats to biodiversity. However, anthropogenic activities also have the capacity to create novel niche spaces to which species respond differently. In 1880, one ... -
Population structure and dynamics of Atlantic herring. A case study of herring inhabiting marginal habitats in Landvikvannet and its vicinity
Berg, Florian (Doctoral thesis, 2018-05-04)Knowledge about the structure and dynamics of marine fish populations is essential for their conservation and management to maintain biodiversity and population complexity. Atlantic herring (Clupea harengus) is one of the ... -
