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

Avoidance reactions of herring to a survey vessel, studied by scanning sonar
(ICES CM Documents;1988/H:46, Working paper, 1988)The behavioural response of a shallow herring layer to a steaming vessel has been studied by the use of a high-resolution scanning sonar technique. When the vessel was completely darkened, no significant reaction important ... -
Back-calculated length at age in Norwegian spring-spawning herring (Clupea harengus L.) : Estimating the common intercept or origin by tuning back-calculated length frequencies to observed ones
(ICES CM Documents;1996/D:9, Working paper, 1996)In Norwegian spring-spawning herring the common intercept of the back-calculating formula, as estimated by linear regression of the fish-scale relationship, grosssly overestimated the back-calculated length frequencie ... -
Cannibalism as a factor regulating year class strength in the Norwegian spring-spawning herring stock
(ICES CM Documents;1992/H:14, Working paper, 1992)The feeding area of the Norwegian spring-spawning herring stock is at present situated in the north-eastern parts of the Norwegian Sea. The eastern parts of the feeding area overlaps with the distribution of drifting ... -
The collapse of the Norwegian spring spawning stock

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. ... -
The correlation between tag-recovery data and VPA-data in Norwegian spring spawning herring

Data on the 1983 year class of Norwegian spring spawning herring from the period June 1985 -August 1986
(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 ... -
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 ... -
