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 (Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS).

Berg, Florian; Almeland, Oda W.; Skadal, Julie; Slotte, Aril; Andersson, Leif; Folkvord, Arild (Peer reviewed; Journal article, 2018)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 (Journal article; Peer reviewed, 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.
