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 (Peer reviewed; Journal article, 2020)

Abundance estimation of Northeast Atlantic mackerel based on tag recapture data - A useful tool for stock assessment?

Tenningen, Maria; Slotte, Aril; Skagen, Dankert W. (Journal article; Peer reviewed, 2010-10)

In the present study we utilize tag recapture data to estimate year class abundance and spawning stock biomass of mackerel (Scomber scombrus L.) in the Northeast Atlantic for the period 1986–2008. On average 20,000 jigged ...

Abundance estimation of Norwegian spring spawning herring at spawning grounds 20 February - 18 March 1997

Abundance estimation of Norwegian spring spawning herring wintering in the Vestfjord system, December 1996

Ostrowski, Marek; Foote, Kenneth G.; Røttingen, Ingolf; Slotte, Aril (ICES CM Documents;1997/FF:13, Working paper, 1997)

The spawning stock of Norwegian spawning herring has been surveyed when wintering in the Vestfjord, Tysfjord, and Ofotfjord, in northem Norway in December 1996. The basic method is that of echo integration, with compensation ...

Acoustic abundance estimation of the stock of Norwegian spring spawning herring, winter 1995- 1996

Standard echo integration methodology has been applied to the stock of Norwegian spring spawning herring (Clupea harengus) wintering in the Ofotfjord-Tysfjord-Vestfjord system during late autumn 1995 and early winter ...

Adult body growth and reproductive investment vary markedly within and across Atlantic and Pacific herring: a meta-analysis and review of 26 stocks

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 ...

Application of Coded Wire Tagging Technology in Pacific Herring to Investigate Stock Structure and Migration

Schweigert, Jake; Flostrand, Linnea; Slotte, Aril; Tallman, Doug; Thomas, J. O. (ICES CM documents, Working paper, 2001)

Tagging of Pacific herring in British Columbia has a long history dating to the mid-1930s but uncertainty in tag recovery locations and low tag return rates limited the utility of these studies. Currently, a larger and ...
