Prey-specific gastric evacuation of Norwegian spring spawning herring (Clupea harengus)
(ICES CM Documents;2004/P:39, Working paper, 2004)Gastric evacuation rates have earlier mainly been measured based on laboratory experiments. The aim of this study is to obtain information of gastric evacuation rates when the herring are feeding in their natural environment. ... -

Recruitment decline in North Sea herring is accompanied by reduced larval growth rates
(Journal article; Peer reviewed, 2013-08-28)The stock of North Sea autumn spawning herring Clupea harengus (L.) has shown an unprecedented 10 yr sequence of sharply reduced recruitment, in spite of a high spawning biomass. Recent work has identified this below-expected ... -
