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). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -

Fishing and environmental variations are major drivers affecting population structure, dynamics, and adaptation of life-history and ... -
Environmental influences on Norwegian spring-spawning herring (<i>Clupea harengus</i> L.) larvae reveal recent constraints in recruitment success
Tiedemann, Maik; Nash, Richard David Marriott; Stenevik, Erling Kåre; Stiasny, Martina, H.; Slotte, Aril; Kjesbu, Olav Sigurd (Peer reviewed; Journal article, 2020)The lack of any abundant recruiting year class of Norwegian spring-spawning (NSS) herring between 2005 and 2015 contributed to an approximate reduction of 40% in the spawning-stock biomass since 2009, i.e. from 7 to 4 ... -
