Adult body growth and reproductive investment vary markedly within and across Atlantic and Pacific herring: a meta-analysis and review of 26 stocks
dos Santos Schmidt, Thassya C.; Hay, Doug E.; Sundby, Svein; Devine, Jennifer A.; Óskarsson, Guðmundur J.; Slotte, Aril; Wuenschel, Mark J.; Lajus, D. L.; Johannessen, Arne; van Damme, Cindy J. G.; Bucholtz, Rikke H.; Kjesbu, Olav S. (Journal article; Peer reviewed, 2021)Life-history traits of Pacific (Clupea pallasii) and Atlantic (Clupea harengus) herring, comprising both local and oceanic stocks subdivided into summer-autumn and spring spawners, were extensively reviewed. The main ... -
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 ... -
The dynamics of a metapopulation: Changes in life-history traits in resident herring that co-occur with oceanic herring during spawning
Johannessen, Arne; Skaret, Georg; Langård, Lise; Slotte, Aril; Husebø, Åse; Fernø, Anders (Peer reviewed; Journal article, 2014-07-22)Different populations of Atlantic herring are regarded as forming a metapopulation, but we know little about the dynamics of the connectivity and degree of interbreeding between the populations. Based on data from three ... -
Seasonal dynamics of atlantic herring (Clupea harengus L.) populations spawning in the vicinity of marginal habitats
Eggers, Florian; Slotte, Aril; Libungan, Lisa Anne; Johannessen, Arne; Kvamme, Cecilie; Moland, Even; Olsen, Esben Moland; Nash, Richard David Marriott (Peer reviewed; Journal article, 2014-11-05)Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June ... -
State-dependent spatial and intra-school dynamics in pre-spawning herring (Clupea harengus L.) in a semi-enclosed ecosystem
Langård, Lise; Fatnes, Ole Andreas; Johannessen, Arne; Skaret, Georg; Axelsen, Bjørn Erik; Nøttestad, Leif; Slotte, Aril; Jensen, Knut Helge; Fernø, Anders (Peer reviewed; Journal article, 2013)Distribution and aggregation patterns of pelagic fish in marine ecosystems are hard to predict and understand, particularly since focused studies are typically limited to single field efforts. Our study targets coastal ... -
