The concept of fecundity regulation in plaice (Pleuronectes platessa) tested on three Irish Sea spawning populations
(Journal article; Peer reviewed, 2007)The fecundity of European plaice (Pleuronectes platessa) in the Irish Sea between 2000 and 2004 was estimated during the spawning season for fish in the three main spawning areas (Liverpool Bay, the Cumbrian coast, and the ... -
The condition of the herring larvae off Western Norway in the period 1985-87. [HELP 31]
(help, Research report, 1990)A herring larval sampling program has been carried out off Western Norway in the period 1985-1988. This paper deals with results from 1985- 1987. Larval growth and condition have been studied both with living and formaldehyd ... -
Correcting for avoidance in acoustic abundance estimates for herring using a generalized linear model
(ICES CM documents, Working paper, 2006)When a research vessel passes over a herring school or layer, the herring may avoid the vessel by swimming downwards and horizontally. The fish may also change its orientation, which may alter its mean target strength. ... -

(ICES CM Documents;1986/H:19, Working paper, 1986)This paper considers the distribution, growth and migration of the 1983 year class of Norwegian spring spawning herring. There are, at present, two geographical components of this year class, one component with a nursery ... -
Deriving condition indices from standard fisheries databases and evaluating their sensitivity to variation in stored energy reserves
(Journal article; Peer reviewed, 2004)To evaluate interstock differences in condition, it would be advantageous to develop stock-level condition indices from standardized databases on weight and length. This study describes a method for estimating stock-level ... -
Determinants of mean length at age of spring spawning herring off the coast of Hokkaido, Japan
(Journal article; Peer reviewed, 2008-08-29)The stock of Hokkaido spring spawning herring Clupea pallasii collapsed in the middle of the 20th century. In the first half of the 20th century, large amounts of spawning herring were caught by set nets at coastal ... -
Differences in swimbladder volume between Baltic and Norwegian spring spawning herring: possible consequences for mean target strength
(ICES CM documents;2007/H:03, Working paper, 2007)Volume and shape of the swimbladder of Baltic and Norwegian spring spawning herring were measured, together with individual herring fat content. Swimbladder size was found to differ significantly between the two herring ... -
Directional responses in herring to sound and noise stimuli

Discrimnation of herring populations in a northern Norwegian fjord: genetic and biological aspects
(ICES CM Documents;1986/H:63, Working paper, 1986)From a trawl survey in a fjord system in northern Norway, it has been possible to separate catches of herring into two distinct groups characterized by different number of vertebrae (VS). Low- vertebral herring (VS = ... -
Distinguishing between spring and autumn spawned herring from daily increments, a preliminary report
(ICES CM Documents;1988/H:15, Working paper, 1988)Otoliths from Norwegian Spring Spawning herring larvae, collected on a cruise in May 1985 and North Sea Autumn Spawned herring larvae, collected on a cruise in Desember 1987, were examined for daily increments. A greater ... -
