Estimating tail-beat frequency using split-beam echosounders
(Journal article; Peer reviewed, 2009-02-04)Data from a standard split-beam echosounder are used to estimate tail-beat frequency within a dense herring (Clupea harengus L.) layer. The data were collected by lowering a horizontally projecting 38 kHz split-beam ... -

Extensive gas bubble release in Norwegian spring spawning herring (Clupea harengus) during predator avoidance
(ICES CM Documents;1998/J:20, Working paper, 1998)Events of extensive gas bubble releases in overwintering Norwegian spring spawning herring (Clupea harengus) were repeatedly observed acoustically and visually in Vestfjorden, northem Norway, during attacks from killer ... -
Extinction cross section of herring: New measurements and speculation
(ICES CM Documents;1994/(B+D+G+H):2, Working paper, 1994)Acoustic abundance estimation of dense, vertically extended aggregations of fish requires knowledge of the extinction cross section. An established method based on a comparison of the area backscattering coefficients ... -

Feeding and migration of Norwegian spring spawning herring in the Norwegian Sea
(ICES CM Documents;1994/R:9, Working paper, 1994)After spawning on the shelf off Møre, Western Norway, the spawning stock of Norwegian spring spawning herring migrates to the Norwegian Sea for feeding. Simultaneously, the adolescent part of the stock leaves the wintering ... -
Feeding of mature cod (Gadus morhua) on the spawning grounds in Lofoten
(Journal article; Peer reviewed, 2008-03-19)Many authors state that cod (Gadus morhua) do not feed during the spawning period. However, this more or less established fact has rarely been investigated in the field. Here, the content of stomachs from Northeast Arctic ... -

Fisheries-induced life history changes in herring (Clupea harengus)
(ICES CM documents;2007/E:23, Working paper, 2007)Fishing changes not only the population abundance of the target species, but also its population dynamics and life-history traits. A number of studies have shown that life history traits related to the timing of maturation ... -
Food and feeding conditions of herring Clupea harengus in the Norwegian Sea
(ICES CM Documents;1996/L:20, Working paper, 1996)The feeding ecology of herring was studied using samples collected during cruises in 1994 and 1995. Investigations were carried out in the Møre shelf region off western Norway where the major spawning of herring occurs, ... -
Food and feeding of young herring larvae of Norwegian spring spawners
(ICES CM Documents;1976/H:36, Working paper, 1976)The gut contents of young herring larvae sampled each hour from 4 to 9 April 1967 around a floating drogue at three depth intervals were examined to study their feeding. Copepod eggs constituated more than 90% of the ... -
